描述

一般說明

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] 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.[6]

Methanol is an alcohol. Its thermochemical conversion to C₂-C₁₀ hydrocarbons in the presence of shape-selective zeolites has been reported.[7] Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.[8]

應用

Methanol has been used during colony-forming unit (CFU) assay and histochemical staining.[9]
Methanol may be used as:

• A solvent for cleaning the coverslips before silanization for DNA combing.[10]
• An additive to improve the octane number of gasoline.[11]
• 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).[12]
• A reactant to prepare dimethylcarbonate by reacting with CO₂ in the presence of graphene oxide-bound octahedral molybdenum cluster (GO-Cs₂Mo₆Brⁱ₈Br^a₆).[13]

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).[14] It may be used in the isolation and quantitative determination of carotenes and xanthophylls from Capsicum annum pericarp extracts by HPLC.[15]
