【Abstract】 Diisooctyl(o-)phthalate was synthesized by the esterification of isooctyl alcohol with phthalic anhydride in the presence of sodium bisulfate monohydrate under single-mode focused microwave irradiation. The effects of the amount of catalyst used, the power and time of microwave irradiation and the ratio of isooctyl alcohol to phthalic anhydride on the conversion rate were also studied. When n(isooctyl alcohol) ∶n(phthalic anhydride)=0.065∶0.025, sodium bisulfate monohydrate 0.30 g,irradiation power 120 W, irradiation time 8 min,the conversion rate of phthalic anhydride is 98.6%.更多还原
