Title:
METHOD FOR PRODUCING ALKADIENOL
Document Type and Number:
Japanese Patent JP2001131103
Kind Code:
A
Abstract:
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.
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.
