Weather-O-lIetcr exposures of Bulux grinds show all products made in #18 Building bo date bo be inferior in ligbtfast* ness or resistance to color change to the old standard Y-403-D, SD-48184 (made with an equal quantity of stannous chloride). One product (1S487 * Condition 1), a 8white base8 procedure sample, is approximately equal to Y-493-D, SD-86721 (78# of the stannous chloride} in color retention and resistance to darkening, 8. Ofae process used for this best product was abandoned in #18 Building because products closer to standard (SD-48184) by H*108 linseed oil greening yellow test would be obtained by means of procedures net involving the precipitation of the white base (lead carbonate) step* A decision Is necessary as to the proper method of evaluation of these products for future production since the conclusions of 1*108 mahouts and Fadeouster exposure do not agree with Bulux grinds and Weather~0*Mq ter exposure* The latter test appears to the writer to be more significant* 3. The presence of vanadium compounds in the bichromate liquor used has vary probably had an adverse Influence on the quality of #18 Building production (as well as on all greens and shading yellows manufactured with such materials) and should be avoided* 4* The effect of sodium bifluoride is qualitatively similar to that experienced in batch operations* 1. Future work should compare the lead carbonate and non-lead carbonate procedures using low vanadium bichromate (18487 - Condition 1 vs 13880 - Condition 1). 8* A trial of the use of a split treatment for stannous chloride is recommended. Wo patent survey was made* PISCBSSIOHi An intensive evaluation of the experimental products made in the continuous unit particularly with reapeot to lightfastness and color retention in Weather-Q*Meter exposure was undertaken* Evaluation of tinctorial properties were confined to 1*108 linseed oil greening yellow tests, Dulux alkyd grinds, and Bulux 1*103 rubouts deference 8) The Weather*o*ii*ter exposures were made in Bulux vehicles mad were conducted because of the fact that Fadeometer evaluations of Chrome Green pigments frequently give misleading information as to the lightfasfcness and color r etemtlen DUP050067288 on out-door expoawe, Fast experience has led to the conclusion that Weather*0*J5eter exposures have proven none reliable* Parti oular emphasis was placed on those plant rone which were considered to have been under good mechanical control, and which yielded pig* ments which were thought to be fairly close to standard tinotorially (13487 * 13330} All ingredient balances, concentrations, etc* used in the plant continuous runs were oheoked and compared with aoral-works K*2241 procedures and with standard batch operations* It was dis covered that both the semi-works and #12 Building continuous processes were using much more sodium sulfide than standard batch manufactures since they were using the material on an analyzed basis (ea* 60%) while standard batch procedures use the material on an "as is** (100%) basis* Xn addition, it sms found that the sodium sulfide rotameter was behaving peculiarly, using more than the calculated amount of this reagent* Buis condition is not thought to have had any serious effect on lightfastness, although definite effects upon color arc to be expected* Two basio processes were used in #12Building. The first of these involves the use of a "white base" procedure as exempli fied by Bun 13487 - Condition 1. and the second omits this "white base" step (e*g* 13330 - Condition l) Evaluation of these products by H-108 linseed oil greening yellow rubout shows the 13330 process to give products which are closer to standard tinotorially* Howover, evaluation in Dalux by means of the Weather-O-Heter shows the white base procedures to be superior In color retention and resistance to darkening* The writer considers the latter evaluation to be the most realistic, short of out-door exposure. Future work should be guided by the Dulux test preferentially, unless this is found to be misleading* The use of "shite base" procedures in #12 Building as applied in runs 13487 - 13530 gave darker bluer masstone greens, somewhat stronger in tint, than runs made without the fbC03 step* This was substantiated in laboratory simulations of #12 Building processes* Little difference In lightfastness of H-108 linseed oil rubouts was notedt however, slkyd evaluation in Weafcher-O-Meter shows "white base" procedures to be superior insofar as #12 Build* ing production is concerned and slightly inferior in a few attempts made in the laboratory* Further evaluation of thie matter is indl* oated particularly since the issue Is complicated by the presence of various amounts of vanadium in the bichromate used* Thie will be discussed more fully later* 1. pH at sodium sulfide (K*368) treatment stage - Con* flicting results upon tinctorial properties were observed by raising pH before sodium sulfide addition in #12 Building* However, light* fastness appeared to be somewhat improved. DUP050067289 It is to be noted that increased quantities of sodium sulfide field lighter masstone products in a non "white base" prosedure* as compared with darker masstone produets in orthodox "white base" procedure for Y-493-D. 2. Effect of adding s tamoua chloride (H-26) in various fashions,* Products made In #12 Building with the use of a vat for stannous chloride treatment seen to he somewhat superior in lightfastness to comparable pigments made with pipeline addition of this compound* This statement must he qualified since the simultaneous change of vat strike versus pipeline strike was made* m general, lighter, bluer, more intense masstone* weaker and bluer tints were obtained* 3h Other comparisons the effect of variation in amount of sodium sulfide complicates the issue since this was also changed simultaneously* the following aspects of the stannous chloride addition have been studied in the laboratory using a #12 Building type process without a "white base"* a. Hydrolysis of stannous chloride solutions prior to use was hot found to be harmful to lightfastneas. tU Increase in stannous chloride quantity to 128$ and 150$ of that used In preparation of Y-493-D, SD~481341* Barker masstone products were obtained which were not better in lightfastness than the control at 100$ of stannous chloride* H* "Split" tin addition i* The use of the "split" stannous chloride addition, similar to that used in batch operations, is to bo recommended* Laboratory products made In this fashion seemed to bo superior to those made with a single tin addition such as was done in the eon* tinuoua plant Y-493-D procedures thus far. . 4. Stirring" longer than two minutes after stannous chloride addition is not recOmmendodi products made with a long stirring time at this point are poor in Ifghtfastneaa* 3. Effect of high vanadium content in bichromate,* It was 1 noted during the course of the laboratory investigation, that eon* trot processes did not appear as good in quality by Weather"0*Meter exposure as produots of a similar type mads in previous Y*493*B studies in the laboratory* to view of the discovery of vanadium in our reoent bichromate purchases. It was decided to investigate Its effect upon quality* Two levels of vanadium quantity were used* The "low" level of *016$ V, on Wag6roO*2%Q basis, and a "high" level of *026$ V were studied in fhelaboratory. (Sasples of bichromate have been reoeived which have contained as much as .137$ vanadium)* Burning on duplicate processes, high vanadium DUP050067290 product;a hove been found to bo fairly close in tinctorial proper ties to low vanadium products with high load chromate content shading yellow, hut considerably darker and bluer with low load chromate content shading yellow* Lightfastness in linseed oil is somawhat worse, and color retention and resistance to darken** ing in Dulux exposures in Weathcr-O-Heter is definitely inferior* 4* Iffeet of PbCrOx content,* It was also noted that those products made in the laboratory at a higher ohrornate con tent are superior to similarly prepared products made with lower chromate content in Fadeometer end Weafchcr-O-Meter evaluation in Baiun* 5* Bee of sodium bifluoride,- (hie plant run, 13530, was made using various amounts of sodium bifluoride in the bichromate solution. The usual effect of producing light masetone greens (at fixed blue content) was noted. Ho other evaluations, such as texture, heat and humidity tests, eto* were wide* The latter test is thought by the writer to be affected by the same mechanism which influence lightfast ness and coles retention In Weather-O-Meter exposures. It is believed that the production of material satisfactory in this latter respect should also be satisfactory in the heat and humidity test* RSii 1* Experimental Details DSN-49-2S RH-44-8S KH-43-105 KB 1319-4-13 Attached letter 8.

The semiworks process represented an adaptation to continuous process equipment of a conventional "white base*1 procedure and did not involve any departures from conventional practice which could be regarded as "radical", This process, K-2241, was taken into the #12 Building unit in May 1948, and 11 runs have been made In the plant unit since that time# The Initial plant run represented an attempt to adapt the semi-works procedure to #12 Building equipment without change, Insofar as possible. However, because the plant unit differs from that in the semi-works in several respects, in addition to the factor of Biss, it was not possible to adapt the semi-works method to the plant without the Introduction of certain changes. The initial material made in the plant by the adaptation of the semi works procedure was of poor quality. Following several plant runs on the seal-works "white base" procedure, without production of material approximating standard or the semi-works product, a procedure was tried which did not involve the production of a "white base"# The material made in the plant by the latter pro cedure appeared to be better in quality than the samples made by the semi-works procedure involving "white base" production and, accordingly, plant studies were continued on this plant modifica tion of the semi-works process# ',4 Eleven plant batches have been made thfca far in the plant in an attempt to develop a satisfactory process. As a result of this study in the plant, products approaching standard in tinctorial quality by the "greening" test have been obtained. However, all such products have been seriously deficient in lightfastness and have, -in general,- shown poor behavior on exposure to heat and humidity. N42210.01 DUP050067293 O'mam mm A memorandum outlining the currant status of this problem, with suggestions for future work* has been prepared by the Development Group, In brief, It is reported that a satisfactory tinctorial match to standard has been obtained, but that the lightfastness and behavior on exposure to heat and humtidity are definitely inferior to those of standard material* Recommendations for further study, involving the investigation of a number of variables, ere alee presented in the aforementioned memorandum* The results of an independent survey of the available infcsrmation by the Inorganic Research Group confirmed the status report by the earlier workers, except that it is felt that the reports of a satisfactory tinctorial match to standard are somewhat optimistic* PROPOSED PROGRAM A review of experimental results obtained thus far reveals that additional experimental studies# either in #12 Bldg* or in the laboratory and semi-works will be necessary in order to arrive at a satisfactory process* It is our opinion that as much as possible of this work should be oarried out in the labora tory., rather than in the #12 Bldg* unit* It is recognised that laboratory and semi-works results cannot always be translated directly into terms of significance for plant operations, but ,i is our opinion that the results of laboratory study of this matter can serve as a very useful guide to plant development investiga tions* For the present, it is proposed to devote our efforts to laboratory studies and to make the next plant run at such a time as laboratory results indicate a definite liklthood of obtaining satisfactory quality material in the plant* It Is believed that such a program will result in a satisfactory solution of the problem more quickly, and with far less accumulation of substandard plant stock, then would be the ease were the experimental study conducted entirely in the plant without the benefit of "guiding* experiments in the laboratory. .BnPtfUTC B.

One plant run was made in 1947, five during 1948, All were based on. the K-2241 ("lead carbonate base") process, embody ing variables designed to reproduce Zabcratory and serai-works conditions.
