摘要
采用在界面上将反应和共沸精馏结合为一体的工艺和具有大比表面积的填料塔，获得了强可逆反应的目的产物。将该工艺和设备应用于由氢氧化钾制取叔丁醇钾的反应，小试和放大试验研究表明，氢氧化钾的转化率达到９３％以上。它比传统金属钾制取叔丁醇钾有明显的技术、经济、安全优势。
The reaction of producing potassium tert butoxide from potash and tert butyl alcohol is an intensive reversible reaction.Because the reaction equilibrium favors the formation of alcohol,potassium tert butoxide can not be obtained without removing the water formed during the reaction.So a technology integrating azeotropic reaction distillation in boundary film and a packed column having large surface area is applied.The potash conversion is greater than 93%.It has obvious technical,economical and safety advantages over the traditional method of producing potassium tert butoxide from metallic potassium.
