Solid superacids ZrO 2-TiO 2/SO 2- 4 can catalyze the esterification reaction of acrylic acid and α-long-chain alcohols with high activities.The catalyst ZrO 2-TiO 2- of Zr/Yi mole ratio 0.25, which was obtained by immersing Zr(OH) 4 in 0.5 mol/L H 2SO 4 for 10 h and then calcining it at 500℃ for 4 h,was used for catalyzing the esterification reaction of acrylic acid and α-long-chain alcohols.The yields of esters was over 95%.
