Soybean oil was transesterified at reflux of methanol in order to test the solid base catalyst prepared from various industrial materials that consist of calcium carbonate. The employed materials were three kinds of lime stones, precipitated calcium carbonate and dolomite, and were calcined at 900 °C for turning them into the solid base catalysts. Dolomite was turned into the most active catalyst for the soybean oil transesterification. The catalyst from precipitated calcium carbonate was active next to that from dolomite. Also, each of three lime stones acted to their own catalytic activity after the calcination. These results indicated that the catalytic activity was influenced by properties of the catalyst precursor. Therefore, effect of the calcination temperature on the catalytic activity was investigated, with related to particle structure of the catalyst precursor.
