SO_4^(2-)/TiO_2固体超强酸催化合成糠酸乙酯的研究

A Study on the Synthesis of Ethyl Furoate Catalyzed by Solid Superacid SO_4^(2-)/TiO_2

以自制糠酸和乙醇为原料,以SO_4^(2-)/TiO_2固体超强酸为催化剂合成了糠酸乙酯,并对反应温度、反应时间、催化剂用量以及反应原料酸醇的物质的量之比等条件进行了考察,结果表明,实验的最佳反应条件为酸醇的物质的量之比1:4,催化剂用量1.5g(当糠酸的物质的量为0.05mol时),反应时间为6～7h,反应温度为60℃。

Ethyl furcate was synthesized from a-furancarboxyic acid and ethanol with solid superacid SO42-/TiO2 as the catalyst. The optimum reaction conditions were as followed: the ratio of acid and ethanol 1 :4, the dosage of catalyst 1.5 g (0. 05 mol acid) , the reaction temperature 60 C , and the reaction time 6~7 hours.
