| Abstract: | In the paper,a method for synthesizing isoamyl acetate byusing E-921 as catalyst was described.The catalyst proceed from strongacid type cation-exchange resin have been treatmented.The optimumcatalytic reaction technological conditions by using a method of evenlydesign have been explored. The quantitative relation of the technologicalfactor was obtained.The catalytic characteristic and technological processof the catalyst used to continual esterification have been studied. |
