Title:
METHOD FOR MANUFACTURING ALIPHATIC TRICARBOXYLIC ACID
Document Type and Number:
Japanese Patent JP2003340246
Kind Code:
A
Abstract:
To provide a method for efficiently manufacturing an aliphatic tricarboxylic acid at a high yield by an electrodialysis process.
This method for manufacturing the aliphatic tricarboxylic acid is characterized in that a water solution (A) containing 1-80 mass % of a basic salt or a partial salt of the aliphatic tricarboxylic acid having a molecular weight of 180 or more is converted to a water solution (B) of the aliphatic tricarboxylic acid corresponding thereto by electrodialysis.
