外文摘要：The solid acid with both Bronsted and Lewis acid sites has been synthesized from resorcinol-formaldehyde (RF) resin, hydroxyethylsulfonic acid and copper hydroxyethylsulfonate. The solid acid was applied to catalyze the transesterification of rapeseed oil. The results showed that the novel solid acid was very efficient for the biodiesel synthesis with the yield over 99% even for the rapeseed oil with high water content and both the free fatty acid and triglyceride could be efficiently transformed to the biodiesel products. The regular sphere structure, low cost, high acidity and catalytic activities gave the solid acid great potential for green chemical processes.
