T - 1, T - 2, T - 3 - cleared paraffin y technical appointment, are intended for use, as a rule, as raw materials in different industries:
T - 1 - is applied to production of goods of household chemicals, in particular candles, and in other industries of national economy;
T - 2 - is applied to use in the chemical, petrochemical industry and in other industries of national economy;
T - 3 - is applied to impregnation and coverings of industrial grades of paper, cardboard, textiles, wood and metallic surfaces; application in the petrochemical industry is allowed.
Paraffin is wax - like substance of white color of crystal structure, with the molecular weight of 300 - 450, in flux possesses small viscosity. The size and form of crystals of paraffin depend on conditions of its allocation: from oil paraffin is emitted in the form of small thin crystals, and from petroleum distillates and distillate raffinates of the solvent refining - in the form of large crystals. At rapid cooling the allocated crystals more small, than at slow.
Chemical formula: mix of saturated hydrocarbons (alkanes) of structure from C18H38 to C35H72.
Paraffin is inert to the majority of chemical reagents. It is oxidized nitric acid, air oxygen (at 140 °C) and some other oxidizers with formation of the different fatty acids similar to the fatty acids which are contained in fats of plant and animal origin.
Paraffin (German Paraffin, from armor. parum - is not enough also athnis - akin; it is called so because of neutrality to the majority of chemical reagents), oil product, mix of alkane hydrocarbons of mainly normal structure with number of carbon atoms from 9 to 40.
Receive paraffin mainly by dewaxing and deoiling of distillate lube stock with use ketone - aromatic solvents. In smaller scales harden paraffin is made deoiling without solvents - the filter pressing of the cooled raw materials with the subsequent sweating of the received gas. For receiving marketable products deoiled paraffin subject to cleaning: sulphuric acid, contact, percolation, gitsrogenizatsionny.
