摘要
Methyl tertiary butyl ether is prepared from contaminated tertiary butyl alcohol and methanol by decomposing peroxides in a peroxides decomposition reactor, by dehydrating the tertiary butyl alcohol to form isobutylene and also decomposing acidic contaminants in a tertiary butyl alcohol dehydration reactor to form a feedstock that is distilled to provide a first lower boiling fraction comprising isobutylene and water; from which isobutylene is recovered for reaction with methanol in an etherification reactor containing a bed of an etherification catalyst to form methyl tertiary butyl ether.
