The Di-(2-Propyl Heptyl) Phthalate was synthesized and catalyzed by solid super acid resin with 2-Propyl-1-Heptanol as raw materials. The effects on esterification yield were investigated by single factor test and orthogonal array design methods. And the notability difference was analyzed with the statistic method of range and variance. Results showed that the optimal conditions were as follows:the ratio of alcohol to acid was 2.9, the catalyst dosage was 0.9%, the reaction temperature was 185℃and the reaction time was 3.5 h. Under the optimal conditions, the esterification yield was reached up to 99.30%. The catalyst was easily prepared and excellent in reaction activity and the wear resistance of catalyst was excellent and can be reused and it was worth to popularize in industry.
