Description

Description générale

Methanol is an industrially important 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. It participates in the purification step during the synthesis of pyocyanin, a toxic compound found in Pseudomonas aeruginosa.

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 alternative to oil and gas to produce hydrocarbon fuels.

Application

Methanol may be used to compose the binary mixtures with acetonitrile in a study. Experimental evaluation of the values of dielectric constant and dielectric loss of these binary mixtures at microwave frequencies at 300°C has been reported.
