| Abstract: | In this paper,triethyl citrate(TEC) is synthesized as environmental friendly plasticizer from citrate acid and ethanol by using aluminiferous mesoporous molecular sieves Al-MCM-41 as catalyst and directly using reactant ethanol as dehydrant.The process methods of replenishing ethanol in batches is used.The result of catalyst contrast and dosage experiment shows that the mesoporous molecular sieves Al-MCM-41 can be used as the efficient and environmental friendly solid acid catalyst for the catalytic synthesis of TEC. |
