General description
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is a biorenewable and thus aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks". Click here for more information.
2-Methyltetrahydrofuran (2-MTHF), a 2-methyl substituted tetrahdrofuran, is a biomass derived solvent. 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 to form secondary chlorides and primary iodides respectively. On long term storage, tetrahydrofuran forms organic peroxides. This process can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT removes the free radicals required for the peroxide formation.
