发明名称 One step synthesis of methyl t-butyl ether from t-butanol using fluorosulfonic acid-modified clay catalysts
摘要 A method is disclosed wherein t-butanol is reacted with methanol in a reaction zone in one step to provide methyl tert-butyl ether and the improvement of accomplishing the reaction which comprises: a. Using a catalyst consisting of a montmorillonite clay, optionally pretreated with a mineral acid, then treated with a fluorosulfonic acid; b. continuously contacting said t-butanol and methanol in a molar amount of about 0.1 to 10 moles of methanol per mole of t-butanol with said catalyst at a temperature of about 20 DEG C. to about 250 DEG C. and a pressure of about atmospheric to about 1000 psig to obtain the methyl tert-butyl ether product.
