1. Introduction to Methanol
Methanol, also known as hydroxymethane, is an organic compound and the simplest saturated monohydric alcohol. Its chemical formula is CH3OH, CAS number is 67-56-1, molecular weight is 32.04, and boiling point is 64.7°C. It is also called "wood alcohol" or "wood spirit" because it was first discovered in dry distilled wood. The lowest human oral poisoning dose is about 100 mg/kg body weight, and oral intake of 0.3 to 1 g/kg can be fatal. Used in the manufacture of formaldehyde and pesticides, etc., and as an extractant of organic matter and a denaturant of alcohol. The finished product is usually made by reacting carbon monoxide with hydrogen.
2. Applications of methanol
Methanol is used as a cleaning and degreasing agent, MOS grade is mainly used for discrete devices, medium and large-scale integrated circuits, and BV-Ⅲ grade is mainly used for ultra-large-scale integrated circuit technology.
Used as analytical reagents, such as solvents, methylation reagents, chromatographic analysis reagents. Also used in organic synthesis.
Generally, methanol is a better solvent than ethanol and can dissolve many inorganic salts. It can also be blended with gasoline as an alternative fuel. Since the 1980s, methanol has been used to produce gasoline octane additive methyl tert-butyl ether, methanol gasoline, methanol fuel, and methanol protein, which promoted the development of methanol production and market demand.
Methanol is not only an important chemical raw material, but also an excellent energy source and vehicle fuel. Methanol reacts with isobutylene to obtain MTBE (methyl tert-butyl ether), which is a high-octane unleaded gasoline additive and can also be used as a solvent. In addition, it can also produce olefins and propylene to solve the problem of resource shortage.
3. Methanol recovery
Methanol, as a better raw material than ethanol, is widely used, and it also brings subsequent waste liquid treatment problems. The pollution of environmental land caused by chemical production is obvious to all. It is an inescapable responsibility to protect the homeland of mankind, and one cannot hold the mentality that it is irrelevant to oneself. Calstar methanol recovery equipment can also purify methanol. The recovered methanol can be reused. Safe explosion-proof, short recovery time, no consumables. A machine can be used for more than 10 years with regular maintenance.
