sphere of application
Raw methanol is widely used in the gas industry in order to combat and prevent hydrate formation in gas production and transportation of natural and associated gas for the testing of new wells and boreholes renovated and partly for the dehydration of natural gas.
In the chemical industry methanol is used as the precursor . In the largest amount of methanol used to obtain formaldehyde , acetic acid , a synthetic rubber , as well as the methylating agent in the manufacture of dimethyl terephthalate , methylamine , methyl methacrylate , pentaerythritol, hexamine . A large amount of methanol consumed for various chemicals such chlorophos , malathion , methyl chloride and methyl bromide , dimethyl sulphate , vinyl methyl ether , dimethylaniline dimetilhlortiofosfata , methyl mercaptan .
Methanol is used in the production of film , amines, polyvinyl chloride , urea and ion exchange resins , dyestuffs and intermediates, the solvent in the paint industry.
In the oil refining industry methanol serves as a selective solvent to clean gasoline from mercaptans and azeotropic agent in the allocation of toluene distillation. In a mixture of methanol and ethylene glycol is used for toluene extraction of gasoline.
Methanol has a high octane number and can be used as part of a motor fuel
MAIN PRODUCT CHARACTERISTICS
Methanol is one of the most important organic products, the simplest representative of the limit of monohydric alcohols.
Methanol is miscible in all respects to water and many organic liquids , but is not miscible with aliphatic hydrocarbons. It absorbs water vapor , carbon dioxide and some other substances
appearance
Colorless transparent liquid without insoluble impurities

Packaging and Storage
Methanol is poured into special railway tanks without bottom drain device , trucks, steel barrels with a capacity of 200 dm3 according to GOST *3950 .
Methanol is not allowed to fill in galvanized containers . Requirements for packaging - in accordance with GOST *6319 .
Methanol is stored in compliance with the rules governing the storage of flammable and toxic liquids and in accordance with the "General sanitary rules when working with methanol "
transportation
Methanol is transported by all modes of transport in accordance with the rules of carriage of goods, operating in this mode of transport .
Transportation methanol rail roads should be carried out only in tank-wagons , in barrels - by road
Product safety information
Methanol - a particularly dangerous flammable liquid . Flash Point 6C . Ignition temperature of 13 oC. Auto-ignition temperature of 440 ° C
 
Methanol - a poison that acts on the nervous and cardiovascular systems . Toxic effect of methanol due to the so -called " lethal synthesis" - the metabolic oxidation in the body to a highly toxic formaldehyde.
Ingestion (5-10) ml of methanol leads to severe poisoning ( one of the consequences - blindness) , and 30 grams or more - death. Maximum allowable concentration of methanol in the air is equal to 1 mg / m ³ ( in isopropyl alcohol 0,6 mg / m³, with ethanol - 5 mg / m³,
Special hazards of methanol due to the fact that the smell and taste of it is indistinguishable from ethyl alcohol , which is why there are cases and its ingestion . Known annual events such as the mass and the unit of methanol poisoning .
Guaranteed shelf life
Guaranteed shelf life Technical methanol - six months from the date of manufacture
