Title:
ALICYCLIC MONOOLEFIN CARBOXYLIC ACID AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2006/088025
Kind Code:
A1
Abstract:
Disclosed is a method for commercially advantageously producing a high-purity alicyclic monoolefin carboxylic acid with less impurities. Specifically disclosed is a method for producing a high-purity alicyclic monoolefin carboxylic acid represented by the general formula (1) below which is characterized by bringing an alicyclic monoolefin carboxylic acid ester represented by the general formula (2) below into contact with an aqueous solution of a carbonate and/or hydrogen carbonate of an alkali metal and/or alkaline earth metal before a reaction step for hydrolyzing the alicyclic monoolefin carboxylic acid ester. [Chemical formula 1] (1) (In the formula (1), R1 represents a hydrogen atom or a methyl group, and n represents 1 or 2.) [Chemical formula 2] (2) (In the formula (2), R1 represents a hydrogen atom or a methyl group, R2 represents a hydrocarbon group having 1-6 carbon atoms, and n represents 1 or 2.)
