FIELD: chemistry.
SUBSTANCE: as the acid catalyst perchloric acid or a mixture of perchloric acid with organic and/or inorganic acids is used. The invention also relates to versions of a method of producing isoprene.
EFFECT: reduced catalyst consumption, high conversion of isobutylene while maintaining high selectivity of conversion thereof, reduced output of by-products at the DMD synthesis step, high equipment efficiency.
