Abstract

The extraordinary preferred standpoint of ionic liquids as solvents and catalysts and different alluring properties in organic chemistry, the preparation, and utilization of ionic liquids have pulled in important interest. In this Paper, we report a series of ammonium and pyridinium ionic liquids which have been synthesized and characterized. These ionic liquids are easy to prepare from amine and pyridine and acids. They have been utilized as catalysts and naturally favorable solvents for esterification of some aromatic acids. Since, esters are vital natural solvents, fundamental chemicals and pharmaceutically interesting chemicals which are broadly utilized as a part of the related industry. The results demonstrate that these ionic liquids are effectively isolated and reusable without losing their action and quality. On the other hand, the conversion and yield got from esterification utilizing these ionic liquids are essentially high. The separation of the desired product was generally performed by extraction with dichloromethane or ethyl acetate and water. The ionic liquids are reused after removal of water under vacuum at high temperature.
