Abstract
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 crystalline aluminosilicate faujasite Y-type zeolite which has been 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.degree. C. to about 250.degree. C. and a pressure of about atmospheric to about 1000 psig to obtain the methyl tert-butyl ether product.
Claims2
An etherification catalyst comprising a rare-earth exchanged crystalline aluminosilicate faujasite Y-zeolite having a surface area greater than 100 m.sup.2 /g and a Si to Al ratio of 1.5 to 3, modified with a fluorosulfonic acid.
