摘　　要：借助高压液相色谱研究了J酸清洁生产新工艺,优化了J酸制备的反应条件,按照新工艺,产品的干品含量(偶合值)高于95%,而杂质异构体γ酸含量低于0.5%,J酸对吐氏酸的总收率达76%,减少了废水的排放.A new technology of J acid clean production was studied to optimize the reaction conditions for preparation of J acid by means of HPLC. With this new method, the content (coupling value) of dried product is higher then 95%, and the content of isomer γacid impurity is less then 0.5%, total yield of J acid based on Tobias acid is 76 percent, and wastewater discharge can be decreased.
