Description and Uses

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?C) and low melting point (-137?C) 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.

ZerO2 products?are rigorously degassed with highly pure inert gas providing solvents and solutions?(anhydrous if specified)?with very low residual oxygen content.
