DICATIONIC ACIDIC IONIC LIQUIDS AS CATALYSTS FOR ESTERIFICATION REACTION BY CONVENTIONAL AND ULTRASONICASSISTED TECHNIQUES

Catalyst development for biodiesel production is an important area of interest as the current production uses corrosive acid catalyst and requires long reaction time. This study aims to develop an alternative environmental-friendly acid catalyst for esterification reaction through ultrasonic-assi...
