General description
tert-Butyl methyl ether (MTBE) is a commonly used organic solvent. It can be synthesized by acid catalyzed reaction between methanol and isobutene. It is an effective alternate to lead containing additives for enhancing the octane rating of gasoline. The decomposition mechanism of MTBE by heat-assisted persulfate oxidation under different conditions has been reported. A study suggests that addition of MTBE increases the number of active sites during polymerization of propene by stopped-flow method.
Application
tert-Butyl methyl ether (MTBE) may be used to synthesize fatty acid methyl esters (FAMEs) and glycerol tert-butyl ether by transesterification of canola oil in the absence of catalyst under supercritical condition.
