Synthesis of Some Organic Ammonium Formate Salts and Study of Their Antifungal Properties

Abstract

This work is concerned with the preparation of a number of organic ammonium formate salts (or ionic liquids; ILs) throughout a reaction between the formic acid and some aliphatic and aromatic amines including the ammonia. Five organic ammonium formate salts were formed, some of them were in the form of solid salts and others were as the ionic liquids (ILs) at room temperature. The yields of the prepared organic salts ranged from (21%) to (79%). However, some attempts towards the preparation of other fifteen organic salts were not successful. The resulting five organic ammonium formate salts/ionic liquids were characterized using a number of spectroscopic techniques such as the infrared (IR), the nuclear magnetic resonance spectroscopy (1HNMR) and the mass spectrometry (ms). The collected spectroscopic data confirmed the formation of theses organic ammonium formate salts. The antifungal properties of the prepared organic ammonium formate salts were investigated against the aspergillus niger (A. niger), and the antifungal results were compared with the antifungal effect of the commercially available antifungal agent Daktarin, which was used as a reference in this study.
