Abstract: An efficient solid-base catalyst with low leaching K2MgSiO4 component on industrial silica gel was synthesized by a simple sol–gel method. The Jatropha biodiesel with high yield of 96.8% was produced by adopting in-situ esterification and transesterification reactions using the solid-base catalyst. The facile methanolysis process with excellent catalytic reactivity depends on the low leaching active component and surface base sites as well as easy dispersed particles in reaction medium. The eco-benign catalyst exhibited consistently high activity after being reused in five reaction runs.
