Methanol, also known as "wood alcohol", is an organic compound and the simplest saturated monohydric alcohol. It is a colorless, transparent, flammable, volatile toxic liquid. Ingestion of 5 to 10 ml can cause blindness, and drinking a large amount can lead to death. Methanol is non-corrosive to metals at room temperature (except lead and aluminum) and has a slight alcohol smell. Relative density 0.792 (20/4℃), melting point -97.8℃, boiling point 64.5℃, flash point 12.22℃, autoignition point 463.89℃, vapor density 1.11, vapor pressure 13.33KPa (100mmHg21.2℃), vapor and air mixture explosion limit 6 to 36.5% (volume ratio), miscible with water, ethanol, ether, benzene, ketones, halogenated hydrocarbons and many other organic solvents. It is usually used as a solvent, antifreeze, fuel or neutralizer.

Product Application of  Methanol CAS#67-56-1

Methanol has a wide range of uses and is a basic organic chemical raw material and high-quality fuel. It is mainly used in the fields of fine chemicals and plastics to produce a variety of organic products such as formaldehyde, acetic acid, methyl chloride, methylamine, dimethyl sulfate, etc. It is also one of the important raw materials for pesticides and medicines. Methanol can be used as a new type of clean fuel after deep processing, and can also be added to gasoline for combustion. Methanol oxidation to formaldehyde Methanol is directly oxidized to formaldehyde in the presence of high temperature, pumice silver, catalyst or other solid catalyst. At present, more than 40% of methanol at home and abroad is used to produce formaldehyde, and then synthesize resins, plastics and other chemical raw materials. Polyoxymethylene is an engineering plastic with excellent performance and its uses are very wide. Formaldehyde is also used to produce nearly 100 downstream products such as butanediol and hexamethylenetetramine. Methanol ammonia to produce methylamine Methanol and ammonia are mixed in a certain proportion, and synthesized at 370~420℃ and 5.0~20.0MPa pressure with activated alumina as a catalyst to produce a mixture of monomethylamine, dimethylamine and trimethylamine, and then distilled to obtain monomethylamine, dimethylamine or trimethylamine products. Monomethylamine, dimethylamine and trimethylamine are used in pesticides, medicines, dyes or as organic raw material intermediates. Methanol can be dehydrated to produce dimethyl ether in the presence of metal silicon aluminum catalyst or ZSM-5 molecular sieve. Methanol is dehydrogenated to produce methyl formate. Methyl formate is a raw material for organic synthesis and can be used to make formamide, dimethylformamide, etc. Formamide is a raw material for medicine, fragrances, and dyes. It can also be used as a paper treatment agent, a softener in the fiber industry, and a polar solvent for organic synthesis. Dimethylformamide is an important organic chemical raw material and an excellent solvent. It can be used as a gas absorbent, pesticide, polyvinyl chloride synthetic leather, polyacrylonitrile spinning, butadiene extraction, etc.
