CHEMICALS INDUSTRIES TO FROM John Dockum J. M. Anderson INTEROFFICE / LAKE CHARLES DATE M""a`rcWh 28, 1969 SUBJECT ^DC Specifications Lake Charles personnel have reviewed the vinyl Idene chloride specifications of Tennessee Eastman and B. F. Goodrich included in your marketing report PMS-2091. We are confident that our purified material will conform to the purity levels required. To be exact, we will meet Tennessee Eastman specification number 1160-1 dated March 1963, with a 50 ppm maximum water limit as noted. We will meet B. F. Goodrich's specifications M-2 and M-32 dated June 24, 1968. Dr. Ron Bartlett reports that the odor and polymerization tests run at Barbwton are favorable. Morpholine in the few ppm range is not detectable, and does not affect polymerization nor impart odor to the polymer. jMAredh cc: I. C. Klimos W. B. Graybill ^ P. R. Arnold J. E.

II September 26, 1968 by F. M. Cummings Status Report FMC/46 I. INTRODUCTION Vinylidene chloride (VDC) produced at Lake Charles does not, at present, meet customer specifications for polymer grade material. While efforts continue toward producing an acceptable material the study of the composition of VDC samples from Lake Charles has also continued, as described in Status Report FMC/42. This report summarizes the results of analysis of VDC samples produced at Lake Charles from May 1 to September 1, 1968. II. EXPERIMENTAL (NBp J-4902,04,09,20; J-6201,08,IT,18,20,21,2^,25,26,27,28; J-4607,08) Eighteen 5-gallon samples of VDC were taken from Lake Charles storage tank at periodic intervals between May 1 and September 1, 1968 and shipped to the Corpus Christi Laboratories in mild steel drums. The contents of each drum were analyzed upon receipt and again following flash distillation, under nitrogen, through a 24-inch Vigreux column into a receiver containing' methoxyphenol. None of these samples met all of the industrially accepted specifications either before or after flash distillation. Emission spectrographic analyses were not done on these samples since previous work (FMC/42) had shown no significant metallic impurities in VDC from Lake Charles. The results of analyses are summarized in Table I while Table II lists VDC specifications from two prospective customers and one competitor. III. DISCUSSION A- p-MethoxyphenoI Concentration - The level of stabilizer in these VDC samples does not represent that of the Lake Charles' storage tanks since additional amounts were added to the drums before shipment at our request.

Peroxide and Water Concentration - The peroxide level found in typical product from Lake Charles is well within customer specifications of 25 ppm. The average water concentration is higher than specification (25-50 ppm) but this is not considered to be a serious problem since drying procedures are readily available. C. Acetylene - VDC produced at Lake Charles contains about twenty times the specified maximum amount of acetylenic material for polymer grade VDC. While acetylene (CsHa) itself has not been detected in these samples, both monochloroacetylene and dichloroacetylene are present in substantial quantities as detected by gas chromatography. Firm quantitative values have not been determined but appear to be within the 500-800 ppm range for each chloroacetylene. These materials are believed to arise from dehydrochlorination of vinylidene chloride leading to monochloroacetylene and of trichloroethylene or tetrachloroethane which gives dichloroacetylene. D. Ionic Chloride - Water extracts of_VDC from Lake Charles show comparatively high levels of ionic chloride (Table I). Whether this chloride is from free HC1, phosgene, or hydrolysis of some impurity, isn't apparent at present. The level is much higher than that- found in samples during the first quarter of 1968. E. Color - Freshly distilled VDC is colorless and clear. However, VDC from Lake Charles rapidly develops a color past the maximum of the APHA scale ( > 500 APHA) while the Dow product remains almost colorless (10-15 APHA) under the same conditions. The color of the Dow VDC listed in Table I is atypical. Distillation of this material produced a color-stable VDC which remained color stable after 300 hours at 50C. F- Assay by Gas Chromatography - VDC from both Lake Charles and Dow meet the specifications for chlorinated hydrocarbons, listed in Table II. However, the Dow material contains less dichloroethylenes,. probably due to a difference in production methods. IV. CONCLUSIONS 1, Lake Charles VDC contains 500-800 ppm of both monochloro- and di chloroacetylene . 2. Vinylidene chloride from the Lake Charles installation consistently fails industry specifications for polymer grade material due to its poor color stability and high acetylene content. SL 044629 FMC/46 - 4 -5 - 3- The level of ionic chloride has increased from an average of 4 to 17 ppm since the first of 1968. The reason for this increase is unknown. V. RECOMMENDATIONS It is recommended that: 1. The exhaustive study of Lake Charles VDC product be discontinued for the present. 2. Effective procedures be found for removing chlorinated acetylenes from VDC. 3* Production processes be altered to prevent formation of chlorinated acetylenes.
