General description

Methanol is an organic solvent that can be synthesized from syngas in the presence of CuO/ZnO/Al2O3 catalysts. It is an ideal candidate as a hydrogen source in fuel cell technology due to its high H/C ratio, low propensity for soot generation, relatively low reforming temperature and as it exists in liquid state at room temperature. In a direct methanol fuel cell (DMFC), methanol undergoes oxidation with air to generate electricity. The olefins (ethylene or propylene) formed from methanol via MTO (methanol-to-olefins) process, can be an alternate to oil and gas to produce hydrocarbon fuels.
Thermochemical conversion of methanol 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.

Application

Methanol (MeOH) has been used in the wholemount immunofluorescence studies of embryonic tissues.
It may be used in the following studies:
  • Colony forming unit-fibroblast assay of bone marrow mononuclear cells.
  • As solvent for the preparation of extracts of hyphae of Aspergillus for the estimation of gliotoxin by reversed phase-HPLC.
  • Immunofluorescence studies.
  • To compose the eluent for the ion-pair reverse-phase HPLC isolation of nucleotides and their decomposition products.
Methanol can be used as a mobile phase in reversed-phase liquid chromatography.
