Abstract: The transesterification reaction of soybean oil with methanol over kalsilite-based heterogeneous catalystsThe kalsilite was synthesized from potassium silicate, potassium hydroxide, and aluminum nitrate aqueousAfter calcination in air at 1200°C, a very porous kalsilite (KAlSiO ) was obtained with surface poresHowever, this kalsilite had relatively low catalytic activity for the transesterification reaction.The catalytic activity of kalsilite was significantly enhanced by introducing a small amount of lithium
