Abstract RU 2270183 C1

FIELD: organic chemistry.

SUBSTANCE: tert-butyl is produced by isobutylene hydrochlorination at temperature from -18°C to -20°C in isobutylene/hydrogen chloride volume ratio of 1.0-1.1:1.0. Reaction mixture is subsequently passed through column filled with ion exchange resin preferably based on polyethylene polyamines and epichlorohydrin, at 1-50°C and at rate of 1.4-1.8 l/h.

EFFECT: method for tert-butyl production of increased yield and improved quality.
