Methanol as a colorless fairly volatile liquid with a faintly sweet pungent odor like that of ethyl alcohol. Completely mixes with water. The vapors are slightly heavier than air and may travel some distance to a source of ignition and flash back.

- Production of acetic acid and formaldehyde. Used as an antifreeze (an additive that is used to lower the freezing point of a liquid) in many pipelines.
- Sewage treatment plants since it serves as a carbon-based food source for denitrifying bacteria.
- A mixture of water and methanol is used in high-performance engines in order to increase power
- Production of hydrocarbons, olefins, and some aromatic compounds
