title: Optimization of biodiesel production by supercritical methyl acetate.
abstract: This work has been done to find out the optimum condition of supercritical methyl acetate method in biodiesel production. The reaction temperature, pressure, time and molar ratio in methyl acetate to oil were the key parameters that must all be considered to produce an optimum condition. Evaluation of thermal decomposition on products, cis-trans isomerization and tocopherol content were required to further optimize the reaction condition. It was, therefore, concluded that for the supercritical methyl acetate method, reaction condition of 350 °C/20 MPa/45 min/42 M ratio gave the highest yields of FAME (96.7 wt.%) and triacetin (8.8 wt.%). Yet, at such a reaction condition, the optimum reaction condition was compromised due particularly to the unavoidable thermal decomposition of products, and tocopherols as natural anti-oxidants.
