詳細

詳細

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 the addition of MTBE increases the number of active sites during polymerization of propene by the stopped-flow method.
