Methanol extensive use, is the foundation of organic chemicals and high quality fuels. Mainly used in chemical industry, plastic and other fields, used to make the formaldehyde, acetic acid, chloride methane, armour ammonia, dimethyl sulfate and so on many kinds of organic products, also pesticide, medicine one of the important raw materials. Methanol in processing after as a new clean fuel, also join mixed burn gasoline. Methanol and ammonia reaction can create a armour amine.
The steam and methanol inflammable, explosive mixture air can be formed, methanol complete combustion produce co2 and water vapor, and gives off heat. Formula: CH3OH + O2 - CO2 + H2O industrial molykote and reserves from carbon monoxide and hydrogen industrial richer mixture (syngas) under certain conditions preparation methanol. Methanol can be used as the solvent and fuel, it is also a kind of chemical raw materials, mainly for the production of formaldehyde. The methanol molecules, carbon atoms to sp3 heterozygous rail metal-metal bonding, oxygen to sp3 heterozygous rail into keys, are polar molecule
