Methods for decomposing esters and purifying alcohols |
摘要 |
A tertiary butyl alcohol charge stock typically contaminated with from about 0.5 to about 2 wt. % of formates and peroxides, is passed through an oxygenates decomposition reactor containing a bed of a decomposition catalyst comprising rhodium, platinum, palladium or mixture thereof at a temperature of from about 100 to about 280C to decompose the peroxides and formates, and to dehydrate a portion of the tertiary butyl alcohol to form isobutylene and water to thereby form a non-corrosive tertiary butyl alcohol feedstock that is substantially free from formates that is suitable for reaction with methanol in a methyl tertiary butyl ether etherification reactor to form a non-corrosive methyl tertiary butyl ether etherification reaction product from which methyl tertiary butyl ether can be recovered.
