CELANESE CHEMICAL COMPANY Chemcel Plant Bishop, Texas t-. Mr. S. W. Fretwell : E. J. Heinz EJH 11-73 June 26, 1973 Celcon Project Report - June - Status of Celcon projects in the Special Problems Laboratory cofect Objective Status and Projection ogen in V- 1011 polymer ) Determine the nitrogen content of V-1011 terpolymer used for blow molding application. Purification of benzene to ah acceptable purity level . ' (99. 99%) for use in the Ticona TEA G. C. method is in pro gress. _ral Analytical (0.6) - Gary, Jackson Plant GC methods were checked and it was found Celcon Method GC-2 is the most reliable for determining the methanol content of T-240 OH. A report **11 be issued. * < The vent off V-1144 (T-249 OH receiver) was analyzed to determine the ncessity of scrubbing the vent to meet the TAQB air emission requirements (CEG 23-73). The cyanoguanidine content (0.125 wt. %) of Lot 301098 was determined by Kjeldahl nitrogen to check for proper blending (CEG 24-73). Two samples of Mobay MDI which were in transit for approximately two *eka were analyzed for dimer content (0.64, 0. 55 wt. %). Ai* Emission - Asbestos air samples taken during the Celanex 3310 run June 18,19,20, 21, 1973 have been sent to.Summit for fiber count. ^en results are obtainedTaafeepwrt.wilt be issued--. 003995 -2 - June 26, 1973 survey is planned for buildings 510 and 533, j been obtained for measuring MDI vapors in air.
