It is an effective alternative to lead containing additives for enhancing the octane rating of gasoline.[2] Application 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.[3] Its addition during the polymerization of propene by stopped-flow method increases the number of active sites.[4] |
