Beschreibung

Allgemeine Beschreibung

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. 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.
