General description
Methanol (carbinol or methyl alcohol or wood alcohol) is a primary aliphatic alcohol miscible in water. It′s a polar solvent used in many organic synthesis reactions. Recently, it has been used in direct methanol fuel cell (DMFC) technology and in the production of gasoline, olefins, and hydrocarbons.
Application
Methanol can be used:
- In combination with magnesium as a reagent for the reduction of ozonides and peroxides chemoselectively.
- In combination with NaNO2 and HCl as a reagent in the diazotization of arylamines.
- As a solvent in many organic reactions like C-C bond cleavage, reduction, cycloaddition, and amination.
