Isomerisasi Eugenol Menjadi Isoeugenol Dengan Metode Sonikasi

Abstract

Isoeugenol is an eugenol derivatives are widely used in the pharmaceutical industries, cosmetics, food and beverage flavor. Conversion of eugenol to isoeugenol made through isomerization reaction. Eugenol isomerization can be done conventionally by heating at high temperature and method use micro wave which required large of energy. In this research, the isomerization is done by using ultrasonic waves in order to produce more efficient method. Isomerization optimal at 70% amplitude condition, within 40 minutes, use ethanol, and the weight ratio of the catalyst RhCl3 eugenol of 1 : 2000. In these conditions produced nearly 100% isoeugenol in total with the composition of 8.23% isoeugenol cis and trans approximately 91.76%.
