The test synthesizes solid super -acid catalyst SO4 2 -/TiO2 and uses it to synthesize sebacic acid 1 -hexanol.It is shown that the highest catalyst activity is exhibited under the conditions of calcinations at 500 ℃ for 3 hours.The influence factors of esterification reflection have been investigated by experiment.The best condition is that n (alcohol)∶n (acid)is 3.0∶1,and the reaction time is 2.5 hours,then the catalyst amount would be 1.3%(the total mass of reactants)and the highest esterification rate is about 98.5%.Also the catalyst has the capacity of being reused and regenerated.
