Used as a solvent in industrial processes, methanol plays a key role in the production of formaldehyde, which is essential for manufacturing resins, adhesives, and plastics. It serves as a fuel additive and alternative fuel in internal combustion engines due to its high octane rating and clean-burning properties. In the energy sector, methanol is a feedstock for producing biodiesel through transesterification of fats and oils. It is also utilized in wastewater treatment to support denitrification by acting as a carbon source for bacteria. In laboratories, it functions as a solvent for chromatography and sample preparation. Additionally, methanol is a precursor in the synthesis of various chemicals, including acetic acid, methyl tert-butyl ether (MTBE), and other methyl esters.
