| Abstract: | A continuous liquid phase esterification process is developed to produce propylene glycol methyl ether acetate.This process utilizes solid acid catalyst.The chemical equilibrium constants are 0 8749 and 0 9118 at reaction temperature 363 K and 373 K respectively.Under the optimized conditions:n(HAc)∶ n (propylene glycol methyl ether)=3∶1,LHSV 4～10 h -1 and reaction temperature 363～383 K,the conversion of propylene glycol methyl ether can be more than 70%,and the selectivity for propylene glycol methyl ether acetate can be more than 96%.The 620 h stability test of the catalyst shows no distinct deactivation. |
