固体超强酸TiO_2/SO_4^(2-)催化双酚-A的研究

Studies on Synthesis of Bisphenol-A Using Solid Superacid TiO_2/SO_4^(2-)

使用固体超强酸 TiO_2/SO_4^(2-)催化合成双酚-A,探讨了反应温度,催化剂用量,反应时间,反应物摩尔配比等因素对反应的影响,最佳条件下双酚-A 的收率为32.9%,同时利用红外光谱对固体超强酸 TiO_2/SO_4^-的酸强度进行了研究。

The synthesis of bisphenol-A from acetone and phenol catalyzed by solid superacid TiO_2/SO_4~2-was introduced in this paper.The effects of reaction tem- pcrature,reaction time,activated temperature of solid superacid TiO_2/SO_4~2-etc.have been studied.Under the optimum conditions,the yield of bisphcnol-A is 33.0%.Re- sult from studies with IR indicates that TiO_2/SO_4~2-is solid superacid.
