Title:
ALICYCLIC MONOOLEFINIC CARBOXYLIC ACID AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2007039429
Kind Code:
A
Abstract:
To provide a method for producing high-purity alicyclic monoolefinic carboxylic acid with reduced impurities through an industrially advantageous process.
Cyclopentadiene and/or dicyclopentadiene and (meth)acrylic acid are subjected to the Diels-Alder reaction and followed by distillation to collect the fraction mainly including alicyclic monoolefinic carboxylic ester represented by formula (1) (wherein R1 is H or methyl, R2 is a 1 to 6C hydrocarbon group; n is 1 or 2). Then, the main fraction is allowed to come into contact with an alkali metal and/or an alkaline earth meatal carbonate and/or hydrogen carbonate to effect hydrolysis.
