Opis ogólny

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.
Methanol is an alcohol. Its thermochemical conversion to C2-C10 hydrocarbons in the presence of shape-selective zeolites has been reported. Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.

Zastosowanie

Methanol may be used for the sodium dodecyl sulfate-polyacrylamide gel electrophoretic (SDS-PAGE) analysis of alkaline protease isoforms isolated from larva of the spotted sand bass (Paralabrax maculatofasciatus). It may be used in the isolation and quantitative determination of carotenes and xanthophylls from Capsicum annum pericarp extracts by HPLC.
Methanol has been used during colony-forming unit (CFU) assay and histochemical staining.
Methanol may be used as:
  • A solvent for cleaning the coverslips before silanization for DNA combing.
  • An additive to improve the octane number of gasoline.
  • A liquid fuel in direct methanol fuel cells (DMFCs).
  • A solvent to synthesize methyl levulinate by acid catalyzed conversion of 5-hydroxymethylfurfural (HMF) and furfuryl alcohol (FA).
  • A reactant to prepare dimethylcarbonate by reacting with CO2 in the presence of graphene oxide-bound octahedral molybdenum cluster (GO-Cs2Mo6Bri8Bra6).
