General description

Methanol is an industrially important alcohol.[1] Its thermochemical conversion to C2-C10 hydrocarbons in the presence of shape-selective zeolites has been reported.[2] Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.[3] It participates in the purification step during the synthesis of pyocyanin, a toxic compound found in Pseudomonas aeruginosa.[4]
Methanol is an organic solvent that can be synthesized from syngas in the presence of CuO/ZnO/Al2O3 catalysts.[5] 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.[6][7] 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.[8]

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.[1]
