Verfahren zur Herstellung von Estern |
摘要 |
<p>The present invention relates to a process for the preparation of esters from alcohols using acetic acid as acetylating agent and clays as catalysts, which comprises the preparation of esters in a single step from the reaction of aliphatic, acyclic, cyclic, heterocyclic, alpha , beta -unsaturated and aromatic alcohols with carbon atoms in the range of C1 to C10 with acetic acid in a molar ratio of 1:3 to 11 using reusable natural montmorillonite/ metal ion-exchanged clay catalysts in the solvent medium of aliphatic, aromatic, or chlorinated hydrocarbons at 30-140 DEG C for a period in the range of 0.02 to 3.0 hrs, and recovering the corresponding esters by simple work-up procedure.</p> |
