METHOD FOR PREPARING TERTIARY BUTYL CHLORIDE

FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to manufacturing chloro-containing hydrocarbons, in particular, tert.-butyl chloride used for preparing addition agents and as activator for dehydrogenation catalysts. Method for preparing involves interaction gaseous isobutylene and hydrogen chloride in the presence of catalyst in the amount 0.02-0.3 wt.-% of parent reagents mass. Water is used as a catalyst. Process is carried out at volume rate of feeding reagents from 1400 h-1 to 1500 h-1, at temperature from 0oC to -5oC and in the mole ratio isobutylene : hydrogen chloride = (1.01-1.015):1 in the bubbling reactor. Method provides elevating yield of tert.-butyl chloride up to 99.2-99.5 wt.-%. ^ EFFECT: improved preparing method, enhanced yield. ^ 2 cl, 1 tbl, 4 ex
