Synthesis of stearic acid triethanolamine ester over solid acid catalysts

The synthesis of stearic acid triethanolamine ester over solid acid catalysts was investigated. The results showed that the catalytic activity and selectivity of zirconium sulfate supported on SBA-15(6) (pore diameter 6 nm) is better than that of commonly used hypophosphorous acid, zirconium sulfate supported on MCM-41 and zirconium sulfate supported on SBA-15(9) (pore diameter 9 nm).
