Due to the increased demand on biofuels, a range of vegetable oils (from the standard rape oil to used frying oil) was evaluated as a potential source of biodiesel production. The characteristics of their methyl ester derivatives were studied. Alkali catalyzed transesterification was conducted in a three-necked glass flask of 1 L volume equipped with a variable speed magnetic agitator, condenser, and thermometer. Out of the total eight biodiesel samples, methyl ester content of three samples was < 96.5%, specified by EN 14214 standard. These were prepared from used frying oils with high polar, dimer, and polymer content. Most of the transesterified vegetable oils fulfilled the required values of acid number (0.5 mg KOH/g sample). This is an abstract of a paper presented at the ACS Fuel Chemistry Meeting (Washington, DC Fall 2005).
