Used as a solvent in industrial processes, methanol is essential in the production of formaldehyde, which is further used to make plastics, paints, and adhesives. It serves as a fuel additive and alternative fuel in vehicles due to its high octane rating and clean-burning properties. In the energy sector, methanol is a key component in the production of biodiesel through transesterification of fats and oils. It is also used as an antifreeze agent in pipelines and windshield washer fluid. In chemical synthesis, it acts as a precursor for acetic acid, methyl tert-butyl ether (MTBE), and other important derivatives. Additionally, methanol is employed in wastewater treatment to support denitrification processes by providing a carbon source for beneficial bacteria.
