일반 설명

tert-Butyl methyl ether (TBME) TBME is a common organic solvent used in the Grignard reaction as an alternative to tetrahydrofuran. TBME has been reported to be a butylating agent for active aromatic systems. TBME is also used to facilitate tert-butyl esterification under microwave conditions.

애플리케이션

tert-Butyl methyl ether is used as a solvent:
  • In the synthesis of acyl azides.
  • In the production of biodiesel.

The kinetics of heat-assisted persulfate oxidation of methyl tert-butyl ether (MTBE) in aqueous solutions at various pH, temperature, oxidant concentration and ionic strength levels was studied. The MTBE degradation was found to follow a pseudo-first-order decay model. The pseudo-first-order rate

We have developed a protocol suitable for high-throughput lipidomic analysis of human brain samples. The traditional Folch extraction (using chloroform and glass-glass homogenization) was compared to a high-throughput method combining methyl-tert-butyl ether (MTBE) extraction with mechanical homogenization utilizing ceramic beads.
