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. 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. Low water content, minimal residue and clean UV spectra are the special characteristics of this solvent. It can be utilized for biotechnological processes like protein sequencing, peptide and oligonucleotide synthesis.

Anwendung

Methanol has been used to fix resolved protein bands on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) gel.
