Description

General description

Methanol (MeOH) is an organic solvent with a wide range of industrial applications. It is the main component of lithium batteries.[1] It can be prepared by hydrogenation of CO₂ under various conditions.[2][3][4][5] Shape-selective zeolite-assisted transformation of methanol to C2-C10 hydrocarbons has been studied.[6] MeOH is a toxic alcohol employed for denaturing ethyl alcohol.[1] A study reports the preparation of biodiesel from canola oil using methanol under supercritical conditions.[7]

Application

Suitable for HPLC, spectrophotometry, and some LC-MS applications
