APPARATUS FOR COPRODUCING ISO-TYPE REACTION PRODUCTS AND ALCOHOLS FROM OLEFINS, AND COPRODUCTION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To increase the area of contact between liquid-phase olefins and vapor-phase mixed gas to increase efficiency in producing aldehydes, and provide an apparatus for coproducing iso-type reaction products and alcohols from olefins and a coproduction method using the same.SOLUTION: An apparatus for coproducing iso-type reaction products and alcohols from olefins comprises: a hydroformylation reactor; a first main distillation column; a hydrogenation reactor; a fore distillation column; a second main distillation column; a post distillation column; and a pipe connecting them; where only one of the first main distillation column and the second main distillation column is operated.
