- W2384297104 abstract "Nonterminal olefin of C13~C14 and maleic anhydride were used as raw materials to prepare alkenyl succinic anhydride(ASA)in a probe reaction.SO2-4/TiO2 solid acid catalyst was used to synthesize ASA.The catalytic activity and stability of the catalyst were studied.The yield was quantitatively analyzed by gas chromatography.The results show that SO2-4/TiO2 catalyst has high activity and good stability in the synthesis of ASA.The optimum conditions are as follows:the calcination temperature of catalyst is 550 ℃,reaction temperature is 190 ℃,reaction time is 5 h,the amount of catalyst is 1% compared with reactant total mass,the molar ratio of nonterminal olefin and anhydride is 3∶1,and the amount of antioxidant 2,6-di-tert-butyl-p-cresol is 0.5% compared with reactant total mass.The yield of ASA reaches 46.8% in the optimum conditions." @default.
