General description

tert-Butyl methyl ether (MTBE) is a gasoline additive. MTBE undergoes oxidative degradation in the presence of propane-oxidizing bacterial strains. The kinetic studies of heat-assisted persulfate oxidation of MTBE under various parameters suggests that the reaction follows the pseudo-first-order kinetics. MTBE can be synthesized by acid catalyzed reaction between methanol and isobutene. A study suggests that the addition of MTBE increases the number of active sites during polymerization of propene by stopped-flow method.
