Beschreibung

Allgemeine Beschreibung

tert-Butyl methyl ether is a commonly used organic solvent. It can be synthesized by acid catalyzed reaction between methanol and isobutene. It is an effective alternative to lead containing additives for enhancing the octane rating of gasoline.

Anwendung

tert-Butyl methyl ether may be used to synthesize fatty acid methyl esters (FAMEs) and glycerol tert-butyl ether via transesterification with canola oil under supercritical conditions. Its addition during the polymerization of propene by stopped-flow method increases the number of active sites.
