Methanol
Methanol (Methanol, CH3OH) is the most simple structured monohydric alcohol with a CAS number of 67-56-1 or 170082-17-4, a molecular weight of 32.04 and a boiling point of 64.7 °C. It is also known as "wood alcohol" or "wood essence" because it was first discovered in dry distillation wood. It is a colorless, volatile liquid with an alcoholic odor. The minimum dose for oral poisoning in humans is about 100 mg/kg body weight, and oral intake of 0.3-1 g/kg can cause death. It is used in the manufacture of formaldehyde, pesticides, etc., and as an extractant for organic substances and a denaturant for alcohol. The finished product is usually produced by reacting carbon monoxide with hydrogen.
