| titleOfInvention | A kind of method for preparing hexacarboxylic acid ester and novel production process method for preparing adipic acid diester product |
| abstract | A method for preparing hexabasic carboxylic acid ester and a novel production process for preparing adipic acid diester products, the method for preparing hexabasic carboxylic acid ester: A, a hexabasic carboxylic acid composition, an alcohol-containing composition and a catalyst are mixed and added to react The kettle is heated to carry out the reaction; B, add water agent to the reaction solution in step A; C add an alcohol-containing composition to the delighting reaction solution in step B for reaction; and obtain hexavalent carboxylic acid ester through the above steps. The method for preparing an adipic acid diester includes A, mixing an adipic acid composition, an alcohol-containing composition, and an esterification catalyst into a reaction kettle for reaction; B, adding a water-carrying agent to the reaction solution in step A; C dehydrating in step B; Add the alcohol composition to the light reaction solution for reaction; D rectify the reaction solution obtained by the reaction in step C to obtain an adipic acid diester product. The invention provides a method for preparing hexabasic carboxylic acid ester and a method for preparing adipic acid diester with high reaction conversion rate, impurity adipic acid monoester content below 1%, adipic acid diester product yield up to 98% or more, and The reaction conditions are mild and the equipment investment is low. |
