METHOD FOR PRODUCING ALKADIENOL

摘要

PROBLEM TO BE SOLVED: To recycle a catalyst without deactivation in producing octadienol from butadiene and water in the presence of a catalyst containing palladium and an organophosphorus compound. SOLUTION: In recovering ocatadienol formed by distilling a reaction product solution and recycling a distillation residue containing the catalyst to a reactor, the distillation residue is subjected to steam distillation, a by-product is partially distilled, the distillation residue of steam distillation is extracted with an aqueous solution of an alkali, an organic acid as a by-product is removed and the resultant substance is recycled to the reactor.
