| titleOfInvention | How to prepare 1,6-hexanediol |
| abstract | The content of impurities such as 1,4-cyclohexanediol, 1,5-hexanediol, 1,2-cyclohexanediol, 1,7-pentanediol, 1,5-pentanediol, and high boiling point components is extremely reduced. Provided is a method for obtaining high purity 1,6-hexanediol.n n n As a method for producing 1,6-hexanediol from cyclohexane,n n n (1) Treating the water extraction concentrate of the reaction mixture obtained by oxidation of cyclohexane with a lower alcohol, esterifying the monocarboxylic acid and dicarboxylic acid contained in the concentrate, while simultaneously water, excess lower alcohol and carboxylic ester Distill and classify; (2) depolymerizing the oligomeric ester contained in the bottom residual liquid in the presence of a lower alcohol, in the presence of a catalyst, under high temperature and high pressure, and converted to a carboxylic acid ester; (3) hydrogenating the carboxylic acid ester classified in the step (1) and the carboxylic acid ester obtained in the step (2), respectively or together, to be converted into 1,6-hexanediol; Way. |
