Product Details

2-Methyltetrahydrofuran CAS#96-47-9

2-Methyltetrahydrofuran (MeTHF or 2-MTHF) is a bio-based solvent that is recognized as the most favorable of ether solvents. The relatively high boiling point (80℃) and low melting point (-137℃) provide a broad temperature range for a myriad of processing conditions. It is a potential greener solvent alternative for organic synthesis. It shows resistance to reduction by lithium making it a promising candidate as electrolytes in lithium batteries. Its polarity and Lewis base strength is intermediate between tetrahydrofuran (THF) and diethyl ether. The ring opening reaction of 2-MTHF has been studied using acid chloride and iodide.

Product Application of 2-Methyltetrahydrofuran CAS#96-47-9

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.
