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