FOR COMPANY USE ONLY DATE April 18, 1972 TEST CONCLUSION NO. TA-C- 72-314 OFFICIAL PRODUCT n a me 1-Bromo- 2,4,6-Triethylbenzene Crude ---------------- ----------------- PRODUCT CODE NO. 113 020POUNDS PRODUCT ACTUAI 18,8 50 AREA. "Ponsol" .BUILDING NAME. Colo rs t it l e TRANSFER THE STEAM DISTILLATION OF 1-BROMO-2,4,6- TRIETHYLBENZENE FROM T-35 to S-12 PREPARED BY:. J. W. Bowman PURPOSE OF TEST: To relieve production scheduling conflicts by transferring the steam distillation step of the 1-bromo-2,4,6-triethylbenzene process from T-35 to S-12. RESULTS OF TEST: Charges 160-173 (18,850 lbs. at standard value) were produced with the steam distillation being done in S-12. The steam distillation of the carbon tetrachloride from-the l-bromo-2,4,6-triethylbenzene proceeded very smoothly. It was noted .that the material distilled in S-12 appeared to be much cleaner and gave better water-organic phase separations than charges distilled in T-35, An apparent 10% increase in yield was also realized possibly due to better itfater washing and phase separation. 'S-12 is Monel and 3,000 gallons whereas T-35 is iron and 1,500 gallons. RECOMMENDATIONS: Steam distill all future production of 1-Bromo-2,4,6Triethylbenzene crude in S-12. t DISTRIBUTION: J.
