摘要
本文研究了固体超强酸TiO_2/SO_4~2-催化乙二醇或1,2—丙二醇与醛或酮的缩合反应,并探讨了固体超强酸TiO_2/SO_4~2-活化温度与催化活性之间的关系,使用活化温度400～500℃的催化剂,最佳反应条件下,缩醛(酮)收率为60％～99％。
In the paper, the catalyst of a solid su-peracid TiO2/SO42- was used in the synthesis of acetals and ketals from aldehydes (or ke-tones) and glycol Cor - 1. 2 - propanediol). The effect of the activity of a solid superacid TiO2/SO42- to reactions was studied. Under the best conditions used,the yields of acetals (or ketals) could reach 60%- 99%.
