Yield:111-55-7 99.61%
Reaction Conditions:
with 1-(3-sulfonic acid)propylimidazole bisulfate ([Ps-im]HSO4) supported silica in cyclohexane at 150; under 760.051 Torr; for 5 h;Pressure;Temperature;Time;
Steps:
1
silica gel as carrier,([Ps-im] HS04) is an acidic ionic liquid,Using (3-chloropropyl) triethoxysilane as the coupling agent,[Ps-im] HS04 was chemically bonded to the surface of silica gel according to the preparation method of acidic immobilized ionic liquid,To prepare an acidic immobilized ionic liquid;And the loading amount of the acidic ascorbic liquid in the acid-immobilized ionic liquid is 5mmol / g;In the batch distillation column (Φ20 × 1400mm) by the molar ratio of 1: 3.8 in the tower were added190 gAcetic acid with51. 7gEthylene glycol,Then added7. 26 gcatalyst,And 40 g of cyclohexane was added to the phase separator as an azeotrope;The temperature of the batch distillation column reactor was controlled at 150 ° C,Reaction pressure control in 1. Oatm,After 5 h of esterification reaction, ethylene glycol diacetate was obtained.
