| Abstract: | By the catalysis of NaHSO 4 instead of H 2SO 4,and in the solution of xylene,the yield of DOS synthesized from phthalic anhydride and 2-ethylhexanol is high up to 98.5%.This new process is characterized by good quality of product,short time of reaction and convenient dispose of product.This catalyst can be repeated for use. |
