General description

2-Methyl-2-butanol is an isomeric form of pentanol. Various physical properties (static dielectric constant, viscosity, density, ultrasonic and dielectric relaxation) of 2-methyl-2-butanol have been evaluated over a wide range of temperatures. Its ability as solvent in the extraction of furfural from aqueous solutions has been tested. Kinetic parameters of the three-phase reaction of MBY with hydrogen catalyzed by a commercial palladium-based catalyst in the absence of solvent have been described.

Application

2-Methyl-2-butanol (tert-amyl alcohol, t-AmylOH, MBY) has been used as solvent for the dissolution of avertin [2,2,2-tribromoethanol), which was employed as an anesthetic in immunohistochemical study. It has been used in the preparation of (E)-2-(2-(3-ethoxy-3-oxoprop-1-enyl)-6-fluorophenyl)acetic acid.
