| titleOfInvention | Synthesis method of 3-amino-4-chlorobenzoic acid cetyl ester |
| abstract | The invention relates to a method for synthesizing high-purity 3-amino-4-chlorobenzoic acid cetyl ester, which takes 3-amino-4-chlorobenzoic acid and cetyl alcohol as initial raw materials, firstly dehydrates under the catalysis of a first catalyst at a low temperature and a negative pressure, then dehydrates under the catalysis of a second catalyst at a high temperature and a normal pressure, dehydrates in two stages to promote esterification reaction, can ensure that the raw materials react completely, can control the generation of impurities, and can ensure that the liquid phase purity of the final product reaches 99.9 percent and the gas phase purity reaches more than 99.5 percent. |
