摘要： A tertiary butyl alcohol charge stock contaminated with from about 0.5 to about 2 wt. % of corrosive oxygen-containing impurities, including peroxides and formates, is passed through an oxygenates decomposition reactor containing a bed of a basic zeolite catalyst to decompose the peroxides and oxygen-containing impurities, including peroxides and formates, and to dehydrate a portion of the tertiary butyl alcohol to form isobutylene and water to form a substantially less-corrosive tertiary butyl alcohol feedstock that is substantially free from oxygen-containing impurities, including formates that is suitable for reaction with methanol in a methyl tertiary butyl ether etherification reactor to form a methyl tertiary butyl ether etherification reaction product from which methyl tertiary butyl ether can be recovered.

摘要： Disclosed is a method for producing alkyl tertiary alkyl ethers which comprises reacting t-butanol with an alkanol in the presence of a catalyst which exhibits extended life comprising .beta.-zeolite modified with one or more metals selected from the group consisting of Group IA and Group IIIB of the Periodic Table and continuously contacting said alkanol and t-butanol in a molar amount from about 10:1 to 1:10 over said zeolite catalyst at a temperature of about 20.degree. C. to about 250.degree. C. and a pressure of about atmospheric to about 1000 psig.
