설명

일반 설명

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

애플리케이션

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