Abstract��
The mixed dicarboxylic acid is a kind of abundant by-product of production process of adipic acid. As a main component in mixed dicarboxylic acid��glutaric acid is a very valuable raw material for fine chemical and has been widely applied to industrial production. This paper aims at the separation and preparation of glutaric acid from mixed dicarboxylic acid. A novel technology involving solution-crystallization��reaction with magnesia-separation and vacuum distillation to obtain highly pure glutaric acid was developed. The proper processing condition was determined experimentally. By the present technique��the glutaric acid with purity more than 99.5% was obtained.
