说明

一般描述

2-Methyl-1-propanol, also known as isobutyl alcohol, is an aliphatic alcohol. The densities, viscosities and refractive indices of the binary mixtures of diglyme and 2-methyl-1-propanol have been evaluated.[1] The partition functions and thermodynamic properties of 2-methyl-1-propanol in the vapor phase have been reported.[2] The kinetics of dehydration of isobutyl alcohol to butene over ZSM (Zeolite Socony Mobil)-5 zeolite has been investigated using in situ FTIR (Fourier transform infrared spectroscopy) and GC.[3] The thermochemical characteristics of radicals generated by the removal of hydrogen from 1-butanol have been studied.[4]
 

应用

2-Methyl-1-propanol may be used in the synthesis of corresponding ester by reacting with acetic acid in the presence of a solid superacid.[5]
