| titleOfInvention | METHOD OF PURIFYING 1,2-DICHLORAETHANE OBTAINED BY OXYCHLORINATION |
| abstract | Chloral and chloroethanol impurities are removed from CH2Cl-CH2Cl, prepd. by catalytic reaction of CAH4 and HCl with air, in gas-phase, at 200-300 degrees C. The hot reaction gas is quenched to 97-105 degrees C, with water, in a wash-zone, under 3-6 bar. HCl is removed. Chloral and chloroethanol are destroyed by reaction with alkali soln. CH2Cl-CH2Cl is sepd. by distn. from cpds. boiling 83.7 degrees C (76o Torr) and >83.7 degrees C (760 Torr). Novelty comprises hydrolytically destroying the chloral and chloroethanol by treating the reaction gases with alkali soln. in wash-zone. Good results are achieved without fitting an expensive separate wash-system (12-25 w.r.t. diagram). Chloral and chloroethanol contents can be reduced from 750- and 250 pmm. to 55- and 40ppm. respectively. |
