Applications

2-Methyltetrahydrofuran acts as a solvent in organic synthesis. It is considered as a replacement for terahydrofuran due to its higher reaction temperature and easy separation after reaction. It is also useful in the electrolyte formulation for secondary lithium electrodes and as a component in alternative fuels. Further, it is used as a solvent for spectroscopic studies at -1960C. It also acts as a solvent for Grignard reagent in organometallic reactions. In addition to this, it plays an important role as a motor fuel.

Notes

Incompatible with oxidizing agents, strong acids and strong bases.

Références bibliographiques

Cryosolvent. Has been proposed as a chlorine-free alternative solvent to dichloromethane in two-phase, including acylation and phase transfer alkylation, reactions. The water-saturated system (ca 39 mL/L) is more polar than the dry solvent, and it forms a useful azeotrope with water (ca 9 : 1), facilitating drying: Synlett, 2353 (2003).
