Title: Synthesis of Di-2-ethylhexyl Adipate Catalyzed by Complex Solid Super Acid SO_4~(2-)/ZrO_2-TiO_2
Abstract: Di-2-ethylhexyl adipate was synthesized with complex solid super acid SO2-4/ZrO2-TiO2 as catalyst.Effects of catalyst dosage,molar ratio of adipic acid to 2-ethyl hexanol,reaction temperature on reaction were studied.The results indicated that the optimum conditions were as follows:catalyst dosage 1.5%(the mass fraction in the total material),molar ratio of adipic acid to 2-ethyl hexanol 1∶2.5,reaction temperature 195~200℃,reflux reaction time 2.5 h.At such conditions,the yield of the product was 97.6%.The catalyst could be reused for six times,and it was easy to regenerate.
