Sonraí Táirge

Methanol, also known as hydroxyl methane, is cumaisc orgánach, is the simplest structure of saturated mono alcohol, its structure is simple CH3OH, can highlight the hydroxyl group of methanol. Because it was first found in retort wood, it is also called “wood alcohol” or “wood essence”. The lowest dose of oral poisoning in humans is about 100mg/kg body weight, and oral ingestion can be fatal by 0.3 ~ 1g/kg. It is used in the manufacture of formaldehyde and pesticides, and is used as an extractant of organic matter and a denaturant of alcohol.

Iarratas

1. Tionscal ceimiceach: MeOH is an important raw material for the synthesis of other chemicals. It can be used to prepare organic compounds such as formaldehyde, esters, ethylene and propylene. These compounds are widely used in medicine, cosmaidí, plaistigh, coatings and chemicals.

2. Energy industry: Methanol can be used as an alternative to petroleum fuels. It can be used as a liquid fuel for combustion to generate electricity, heat and run cars. Freisin, chemical methanol can also be prepared into hydrogen and syngas by catalytic conversion for hydrogen energy and fuel cell technologies.

3. Tuaslagóir: Methanol is a commonly used solvent with high solubility and volatility. It can dissolve many organic compounds and is widely used in the preparation of paints, ruaimeanna, cleaning agents and personal care products.

4. Antifreeze: Since methanol has a low freezing point, it can be added to the liquid as an antifreeze to prevent freezing and damage to the cooling system.

5. Pharmaceutical and medical applications: Methanol is an ingredient in many medicines and medical products. It can be used in the preparation of oral drug solutions, disinfectants, disinfectants and solvents in the process of drug preparation.
