Пентенилхлориды на основе изопрена

The research of methods for producing of isoprene hydrochlorides are carried out. It is shown that the interaction of isoprene with concentrated hydrochloric acid gives yields of pentenilсhlorides two times higher than with using of gaseous hydrogen chloride. The influence of additions in liquid-phase hydro-chlorination of phase-transfer catalyst – triethyl-benzylammonium chloride and an emulsifier polyvinyl acetate on the selectivity of formation of isomers was shown. Optimal conditions for synthesis of 3-chloro-3-methyl-butene-1 are sekected. Physico-chemical characteristics and structure of the obtained chloropentenes are determined.
