The cycalohexane carboxylic aid (CCA) membrane separation process was studied in order to solve the problems of long operation process, high requirement of equipment and high energy consumption for the separation and purification of the CCA. Through the flow filtration test, CCA can be purified by membrane separation from benzoic acid hydrogenation reaction mixture. The membrane separation process can reduce energy consumption and improve economic benefit, and realize industrial production instead of vacuum distillation process.
