product description

Methanol, also known as "wood alcohol", is an organic compound and the simplest saturated monohydric alcohol. It is a colorless, transparent, flammable, volatile toxic liquid. Ingestion of 5 to 10 ml can cause blindness, and drinking a large amount can lead to death. Methanol is non-corrosive to metals at room temperature (except lead and aluminum) and has a slight alcohol smell. Relative density 0.792 (20/4℃), melting point -97.8℃, boiling point 64.5℃, flash point 12.22℃, autoignition point 463.89℃, vapor density 1.11, vapor pressure 13.33KPa (100mmHg21.2℃), vapor and air mixture explosion limit 6 to 36.5% (volume ratio), miscible with water, ethanol, ether, benzene, ketones, halogenated hydrocarbons and many other organic solvents. It is usually used as a solvent, antifreeze, fuel or neutralizer.

Product Usage

Methanol, often referred to as wood alcohol, is a fundamental building block in the global chemical industry. Its most significant application is as a feedstock for producing formaldehyde, acetic acid, and various plastics, fibers, and resins. In the energy sector, methanol is gaining prominence as a clean-burning fuel or fuel additive, contributing to reduced emissions in marine and automotive transport. Furthermore, it serves as a high-performance industrial solvent for paints, varnishes, and inks, and is essential in wastewater treatment as a carbon source for denitrification.
