Web6 Dec 2006 · 2-Methyltetrahydrofuran (MeTHF) is a commercially available solvent that is produced from renewable resources. The properties of MeTHF place it between tetrahydrofuran (THF) and diethyl ether in solvent polarity and Lewis base strength. In many cases, MeTHF can replace THF in organometallic reactions. The formation and reaction … Web5 Jan 2006 · Abstract Tert-butyl alcohol and water form an azeotrope at normal pressure. Simple distillation cannot be used to separate these two components. In this article, a systematic study of the separation of tert-butyl alcohol–water mixtures with an entrainer by heterogeneous azeotropic batch distillation was performed.
