| titleOfInvention | Process for preparation of esters solvent |
| abstract | The present invention provides high boiling point esters solvent with low content of sodium and acid and high-efficiency industry method for preparing the same. The esters solvent can be used in electronic material field with requirement of high-purity quality. Process for preparation of esters solvent is, at the presence of acid catalyst, putting the esterification reaction stock solution got from esterification of alcohol and acid into distilling tower and distilling to get esters solvent, wherein, the reaction stock solution used for distil purifying without neutralization treatment, and after removing low boiling point ingredients by distillation, distilling off the esters solvent via sidetrack distillate pipe disposed in central part of the distilling tower. |
