Methanol Chemical Properties
Methanol with the chemical formula CH3OH exhibits several chemical properties, which is:
- Acidity and Basicity: Methanol is a weak acid and a weak base. It can donate protons (H+) to stronger bases and accept protons (H+) from stronger acids.
- Reactivity: Methanol is a reactive chemical that can undergo a variety of reactions. It can be oxidized to form formaldehyde, reduced to form methane, and reacted with halogens to form alkyl halides.
- Flammability: Methanol is a liquid with a flash point of 11.7 °C. This means that it will easily ignite and can produce explosive vapors.
- Toxicity: Methanol is a highly toxic substance that can cause blindness, kidney damage, and death. It is essential to handle Methanol carefully and avoid exposure to it.
- Combustion of Methanol: When methanol burns in the air, it forms carbon dioxide and water. It is highly flammable and burns with a pale-blue, non-luminous flame. The chemical equation for the combustion of methanol is:
2CH3OH + 3O2 → 2CO2 + 4H2O
pH of Methanol
The pH of methanol is 8.3. Methanol-water mixtures have autoprotolysis constants between 14 (water) and 16.6 (methanol), so neutral in these mixtures ranges from pH 7 to pH 8.3
Methanol Boiling Point
Boiling point of methanol is 64.7 °C
Methanol Density
Density of methanol at room temperature is 791.80 kg/m³
Methanol Molecular Weight
Molecular Weight of methanol is 32.04 g/mol³
Methanol Formula
Methanol is the simplest form of alcohol, which is colorless, volatile, and highly flammable. Methanol is also referred to as Methyl Alcohol or Wood Alcohol. It is an excellent fuel and has the potential to run automobiles, fuel cells, and gas stoves. It plays an essential role in various reactions, ranging from esterification to acting as a hydrogen source.
In this article, we will study methanol, its structure, properties, production methods, along with its environmental impact in detail.
