| titleOfInvention | The Purification Method of High Purity Glycol Diesters By the Effective Removal of the Catalyst |
| abstract | TECHNICAL FIELD The present invention relates to a method for purifying a glycol diester, and hydrolyzing using an aqueous sodium hydroxide solution in the process of preparing a glycol diester using a titanate catalyst using glycol monoester and aliphatic carboxylic acid as raw materials. It provides a method for stably purifying a high-purity glycol diester by effectively removing the titanate-based catalyst from the reaction product by using a filtration process and, according to the present invention, the reaction product using a hydrolysis and filtration process By effectively removing the titanate-based catalyst dissolved uniformly in the product, it is possible to prevent product loss and discoloration by the catalyst during the distillation process to refine the final product and to stably separate high purity products. |
