Title: Catalytic Synthesis of Diethyl Succinate by Ce(SO_4)_2/SiO_2
Abstract: Ce(SO_4)_2/SiO_2 was first applied to esterification of succinic acid with ethyl alcohol.Content of active constituent of the catalyst was a little.But the catalyst had high activity and no corrosion to the facilities.Reaction product was separated easily. The catalyst was an environmentlly friendly catalyst.Reaction conditions were studied. The optimum condition was obtained as follows: supported ceric sulfate 15%, succinic acid 0.1mol, ethyl alcohol 0.7mol,catalyst 1.0g, reaction time 120min. In the optimum condition, the rate of esterification was 91.5%.
