| Abstract: | In the catalytic distillation process, maleic anhydride and ethanol were used as raw materials, Kerry Chemical Corporation developed KC104 strong acid cation exchange resin as catalyst, the synthesis of plasticizer maleic acid diether ester （DEM） was proceeded in a catalytic distillation reaction device. The optimal reaction conditions are： n（ethanol）/n（maleic anhydride） =1.5, space velocity of 1.5/h, the reaction pressure is 0.5 MPa, the temperature conditions of 100 ℃, the catalyst is KC104 resin catalyst, the yield of DEM is above 98%, the conversion of maleic anhydride is up to 100%. |
| Keywords: | maleic acid diethyl ester catalytic distillation plasticizer |
