摘　　要：概述了国内己二酸生产中的副产物尼龙酸的应用领域以及尼龙酸的应用研究进展。目前,尼龙酸下游产品的开发主要集中在高沸点溶剂和耐寒增塑剂。在高沸点溶剂的开发方面,根据合成溶剂中所用催化剂不同,对比了不同催化剂催化尼龙酸合成混合二元酸二甲酯的工艺过程;在耐寒增塑剂的开发方面,以尼龙酸与丁醇、异丁醇、辛醇等反应制备不同的产品,分析了合成工艺条件;其次,尼龙酸可作为聚氨酯原料或经分离提纯制备戊二酸和丁二酸等。今后应不断提升经尼龙酸为原料的产品质量稳定性和附加值,扩大尼龙酸的应用。The application field and progress of nylon acid,a by-product of adipic acid production,was summarized in China.The development of down-stream products of nylon acid has mainly focused on high-boiling point solvents and cold resistant plasticizers so far.As for the development of high-boiling point solvents,the catalytic synthesis process of mixed dibasic acid dimethyl esters from nylon acid was compared in presence of different catalysts.As for the development of cold resistant plasticizers,the synthesis process conditions of the products were analyzed by reacting nylon acid with butanol,isobutanol and octanol,etc..And nylon acid can be used as the raw material for polyurethane or glutaric acid and succinic acid through separation and purification.The steady quality and added value of the products using nylon acid as raw material should be enhanced and the application of nylon acid should be expanded in the future.
