Therminol food users are converting to Therminol 66 or Therminol 55# with little loss of business. Customer letters for notification of Pydraul F9A are prepared and will be Issued when manufacture is complete (estimate 2 weeks). The withdrawal/replacement program for Aroclor plasticizers appears to be going well. Several customers have reported success in reformulating in such applications as epoxy coating/potting systems and inks. Production orders for the.' products being withdrawn have been very heavy, however, the producing plants and production planning have done an excellent Job of keeping shipments moving in an orderly fashion.' . ' ENGINEERING; * Aroclor Incineration ' . A preliminary project scope for a 10 IT pound/year liquid incineration system was developed and issued for review. A safety review was held. The project scope is being modified to reflect comments received. The appropriation request data transmittal will be Issued in early Avgust. TRAN 036311 ^dfcOTudUr HARTOLDMONOQ43284 / -2 =r.'QI>.'55RING: (continued) . KCS-101'6 Distillation / Economic analyses to establish method and location for distilling 55 IT pounds/year of MCS-1016 were completed and issued. The preliminary project ' scope was prepared and Issued for comments. A safety review has Just been held. The appropriation request data transmittal will be Issued In early August. * There has been little new activity during July. ' Neither of the NERC reports has yet been published, although the new journal "Envlroamcntal Pollution" , carried the paper- written by the Monk3wood people on the avian toxicity of PCB's. This provoked one or two reports In the popular press. i A NATO committee Is sponsoring an Investigation Into marine pollution along the coast from Calais to the north of Holland, with special referonce to PCB's. They were advised to get In touch with Bayer and Prodclec for Information on the usage of PCB's In Belgian and within the whole of the EEC. Implementation of the PCS plan for Europe Is held up pending further meetings with the other PCB producers, firstly to determine their attitude towards a voluntary withdrawal from uncontrollable applications, and secondly to determine their reaction In the event of a unilateral withdrawal by Monsanto. . JAPAN No new public developments In Japan. KMK writing a revised policy for marketing of Aroclors. U.S.A. customers (3M# Thlokol) Investigating Japanese sources. . i' TRAN 036312 HARTOLDMONOQ43285 -3- MEDICAL Two year feeding studies continue. Twelve month status report Is expected In August. Pish toxicity studies are being repeated as well as some of the chicken reproduction studies. PDA has Issued guidelines establishing upper limits on PC3 contents In milk at 0.2 ppm and other food at 5*0 ppm. . PUBLIC RELATIONS i A nows rolease on Monsanto's rocent actions to curb the use of PC3 was distributed on July 16. It was primarily a rebuttal to recent stories that PCS caused birth defects, but Included a complete background of voluntary actions taken to solve the PCS problem. Copies went to all nows media who'have carried PCB stories In tho past two yoars. f Use of our story by the press has been light. */ TRAN 036313 I HARTOLDMON0043286 Aroclor 1242 Replacement for NCR The two major problems with nonoisopropyl biphenyl (''.IPS) are now defined as odor and eye irritation. Both problems could be solved by changing from propylene to a higher olefin for alkylation of biphenyl. I\aJor Interest Is now centered on Cg o alkyl biphenyl (ABP-11) from Ethyl Corp. 0^ -oI6rin, our oxo process feedstock. Early testing by NCR was highly encouraging* however, print fade looms as a major problem. Back-up candidates Include butyl* amyl* and hexyl biphenyl. j A series of six odor masks were provided NCR in an effort to improve the odor of MIPB without interfering with solvent performance. : Samples of extender and cosolvents were supplied to NCR to Improve dye solubility and to give more rapid color development than NCR's current cosolvent. These materials are (l) heads fraction from alkyl benzene manufacture at Chocolate Bayou* (2) alkyl benzene (Alkylate 215)* and (3) alkyl benzene high boiler (Alkylate H-230). . Plasticizer Replacements ' Blends of Aroclors 5^60, 5^42 and 1221 were developed to approximately match the viscosities of Aroclors 1254* 1248 and 1242. Replacement recommendations were made to customers to whom viscosity is important. Specifications are being developed in cooperation with the Anniston Laboratory. '1 NCS-IO16 Sixteen drums of the MCS-1016 have been prepared by fractionating Aroclor 1142 In a packed column equivalent to 25 trays In the Dayton Pilot Plant. The distillate was brought hero and analyzed. Then the fractions wore recombined to give the desired composition'and treated with a Porocel column to give tho doslred electrical properties. The product, is now ready for shipment to customers for testing in capacitors. Since all the electrical properties of KC3 are Indistinguishable from those of Aroclor 1242 and there are only minor differences In other properties* this fluid should be a direct substitute for Aroclor 1242 in the capacitor Industry with no capacitor design change or processing changes needed. TRAN 03631* HARTOLDMON0043287 -5- RSSEARCH: (Continued) Industrial Fluids Pydraul JMI& Pydraul F-9 was reformulated as Pydraul F-9A to avoid the use of chlorinated biphenyl. Tne new formulation is compatible with F-9. The lubricity in V105E pump tests is superior to any fluid we have ever run, . NC Phosphate Ester Manufacturing costs are directly proportional to reaction times in the Step I reactor. We demonstrated that foaming in the Step I lab reactor and reaction time could be reduced by concurrent addition of POCI3 and nonylphenol/ cumylphenol. mis should bring the reactor cycle to <6 hours. The process pay-load might be further increased by employing the SchottenBaumann Step II and III reactors. me pilot plant is reworking 1000 pounds of plant material by add hydrolysis and washing to reduce acidity and hydrolyzable material. Aroclor Substitutes ' Bromoaroclor 1233 (15 Br) was scaled-up in a 33 gallon run in the Pilot Plant, mis fluid is being tested in hydraulic fluid applications as a more biodegradable replacement of chlorl- natod biphenyl. j 4 Isomerization of chlorinated terphenyl 3032 results in a fluid with a 100? vlsoosity of 2800 cs and a 210F viscosity of 11.7- We are seeking the lowest viscosity, all liquid torphonyl for use in hydraulic fluids, . a-Koth^lstyrene diner was mono and diehlorinated for evaluation as a plasticizer in place of chlorinated biphenyl. TRAN 036315 HARTOLDMON0043288 -6 RESEARCH: (Continued) Biodegradation - Ruabon . Priority has been given to the development of more refined GLC analytical techniques so that more selectivity will be available for degradation studies of multicomponent PCB's such as Aroclor 1242. This has caused some delay, but work in progress Includes biodegradation studies of Pyralene 1500 (a competitive product), two of the key Isomers for assessing the viability of the theoretical mechanism for degradation and HB-40. We are also studying the soil culture which Professor Evans, at Bangor University, has said will grow on Aroclors 1242 or 1254 as sole carbon source. ' . Biodegradation Testing - St. Louis . Testing of Aroclor 1242, Aroclor 1254, mcs-1016 (Aroclor 12423), and Aroclor 1230B in our semi* continuous activated sludge units will be started as soon as sample background problems have been resolved. Identical conditions will be employed to permit a comparison between our present Aroclor product and the proposed substitutes. ?-!ANUFACTURINQ Anniston Current Level Aroclor losses during July averaged 3280 ppb in the plant effluent. Ibis Is equal to 38 pounds/ day of Aroclor. ' Plant Effluent Suspended Aroclor Control Aroclor sump construction continues. Revision requesting an additional $4500 has been prepared. Ibis was necessitated by unforeseen ground water problems. Completion by 9/1/70 still appears possible. . 1. 0 1 TRAN 036316 HARTOLDMON0043289 -7- MAKUPACTURIKO: (Continued) Sulk Waste Disposal Data defining magnitude of solid material quantities will be completely collected by week of August 31, Quantities and the basic estimates from which they are derived will be discussed with Production and TSD representatives . August 6. / Laboratory testing of mixtures of Montar 1 and / . Montar 5 were not dramatically successful In /: reducing pumping temperatures required - 200C7 range still necessary. ' Experiments with hydrocarbon dilution of chlorinated and unchlorln&tcd Montars appear to Indicate this as an extremely attractive route to effectively reduce pumping temperatures, . In some cases to near ambient. Economic evaluations will be made In the next two months. If successful, this will reduce handling costs and also provide auxiliary fuel for Incineration. Saugct . PC3 Levels In Sewer Current losses are about pounds/day to the ` . river which Is a concentration of 200-230 ppb. . Memo being published by M. Plerle covering the > sampling program for the plant. The Aroclor ' Department and total plant effluent will be monitored dally. Current effort Is to Improve the sampling technique. Aroclor analyzer received and laboratory Is ready for routine analysis. Sampling will begin on a routine basis this week. 1 PC3 Levels In Atmosphere Points of loss have been determined. Report being publlehod. Most severe losses are from Thormlnol units In Departments 239, 2b5, 24Q and 233* Work begun to eorreot those areas. TRAN 036317 HARTOLDMON0043290 -8- KA?IU?AC?URIKO: (Continued) Equipment has been purchased to take vapor sar.ples. Where vapor Is flowing, losses can be measured quantitatively. Where vapor flows cannot be measured such as in breather vents, qualitative results will be obtained. Will complete this as per schedule by September 1, 1970.
