methanol

Industrial poison GOST 2222-78

One of the most significant organic product, both in importance and production volume. In our company the product is obtained through catalytic hydration of carbon oxides by hydrogen using low-temperature catalyser SNM-1 under the excess pressure of 50 kg/sm3.

Structural formula

Methanol is produced in 2 forms: Crude and Rectified.

Crude Methanol, besides Methanol - CH30H, contains water and dimethyl either and is mainly used in gas industry to dilute the accumulations of hidrated in pipelines, to denitrify effluents and other purposes. Rectified Methanol is obtained through cleaning crude methanol by distillation in rectification columns.

APPLICATION

Methanol is used as semi-product in many industrial syntheses. The main consumer is the production of formaldehide, which is used to manufacture formaldehide resins, plastics and synthetic fibres.

In oil-processing industry methanol is used as selective dissolvent to clean gasoline from mercantanes and also, in the extraction of toluene.

Besides, Methanol is used to obtain a fuel additive with high octane content (which result in the increase of the engine power and in the steep decrease of exhaust), in protein synthesis (protein-vitamin concentrate), in the production of dymethylreftalate, pesticides and agents for chemical protection of vegetation; in the production of acetic acid, hexamine, carbamide resins, photofilm, plexiglass.

SECURITY REQUIREMENTS

Methanol is colorless, easily flammable toxic liquid, with flash point - 8C, self-ignition point - 436C. Range of ignition: 6,7-34,7 of volume fraction.
