The invention relates to the composition of the antiseptic oil viscous and can be used for impregnation of wood, in particular for impregnation of wood sleepers and rails.

Known impregnating material which is a mixture of coal oil (GOST 2270-74 "coal Oil for impregnation of wood") and petroleum oil softener manufactured according to TU 38.301.08-31-89.

However, in the preparation of the working mixture, consisting of coal oil having a density at a temperature of 20°within 1090-1130 kg/m3and oil softener having a density at 20°within 890-910 kg/m3, using as a mixing agent of acute water vapor, after cooling and sludge in the tank is formed of a three-layer system: bottom layer - coal oil; the middle layer is water; the upper layer of oil oil - softner. To maintain in the tank homogeneous system requires periodic circulation moving components of the mixture according to the scheme: tank → pump → tank, which leads to additional energy consumption. The system is not released from the water.

Known coal sleeper impregnation oil (GOST 2270-74)containing in the structure a narrow oily fraction of thermal origin and represents a mixture of the first anthracene FR the functions (280-360° C) and the absorption oil (235-300° (C) [Handbook of koksohimiko, Vol.3, Ed. engineer Akkalkuwa. - M.: Metallurgy. - 1960. - P.66].

The disadvantages of coal sleeper impregnation oil include the following factors:

1. Coal sleeper impregnation oil contains up to 0.3% of matter insoluble in toluene (carboids and carbenes), and up to 1.5% of water, which negatively affects the process of impregnation of the wood.

2. Toxicity of coal sleeper impregnation oil belongs to the second class (highly hazardous), which creates an increased danger from the point of view of the sanitary-hygienic and ecological status sleeper impregnation plants.

3. Coal sleeper impregnation oil has a relatively high freezing point (minus 2 to minus 5° (C)that makes its draining and pumping in winter conditions at lower ambient temperatures.

4. Coal sleeper impregnation oil is prepared by mixing and co-crystallization of the 1st anthracene fraction and absorption oil with subsequent separation of the crystals in the centrifuge. 2.5 m3the absorption oil in the mixture injected 7.5 m31st anthracene fraction. After crystallization and centrifugation output of the crystals amounts to 15-20% in the mixture (Handbook of koksohimiko, Vol.3, Ed. Acche the Cove. - M.: metallurgy - 1966. - P.66).

5. A significant drawback of coal sleeper impregnation oil is its tendency to sedimentation, resulting in the need to "erosion of sediment in tank wagons and the deadweight losses when storing it in tanks.

6. Coal sleeper impregnation oil (creosote) has a sharp, unpleasant and very long lasting smell and is vysokoenergichnym organic matter.

The closest technical solution to the claimed invention is "Antiseptic oil for wood impregnation" (patent of Russian Federation №2191110, 27 To 3/50, 20.10.2002,).

Known antiseptic contains a wide mixture of the residual fraction of the high temperature thermal cracking, wikipeida within 150° - K.K., viscosity regulator - wide fraction of thermal gasoil with the beginning of the boil 215-230°stabilized by the flash point determined in an open crucible, not less than 95°in the following ratio, wt.%:

- wide residual fraction
high temperature thermal cracking,
wikipeida within 150°S - K.20-50
- wide fraction of thermal ha is EULA
with the beginning of the boil 215-230°C
stable temperature
flash in an open crucible, below95°With 50-80

To the disadvantage of the known antiseptic liquid is:

Use as a viscosity regulator - wide fraction of thermal gasoil with the beginning of the boil 215-230°With which, along with the performance of the basic, positive role of the regulation (decrease) viscosity adjusts the color, exerting a negative influence on the quality of antiseptic - affects (reduces) its color, making it lighter, which ultimately reflects on the process of control of the depth of impregnation of railway sleepers.

The present invention solves the technical problem of increasing the resources of oily antiseptics for wood impregnation and improve their color (antiseptic for impregnation of wooden sleepers should have a dark color) due to the rational use of oil residue distillate and residual origin.

The invention consists in that the antiseptic viscous oil containing a mixture of broad fraction of thermal cracking and organic color control, according to the invention as a broad fraction of thermal cracking process contains a fraction of heavy solubilize, wikipaedia within 200° - K.K., and as a regulator of color - fraction oil, wikipaedia within 220° - K.K., in the following ratio, wt.%:

the fraction of heavy pyrolysis resin,
wikipeida within 200°KK70-95
- fraction of fuel oil, wikipeida
within 220°KK 5,0-30

The specified fraction of heavy pyrolysis resin and color control - fraction of fuel oil, was obtained as follows.

Raw (straight-run gas oil or gasoline fraction, or a mixture of gases With2-C4) is subjected to pyrolysis at industrial installations. The result: sin and liquid products of pyrolysis.

The sin differentiates him ethylene, propylene, butylene. Liquid products (pyrolysis resin) divided by the required number of fractions, such as gasoline C5- 180 (200° (C) is a lightweight resin or the pyrolysis condensate fraction and a heavy tar fraction above 200° [Akhmetov S.A. Technology of deep processing of oil and gas. Publishing house "Gil" - Ufa - 2002].

Dehydrated and desalted oil is subjected to fractionation (separation into fractions) in the primary distillation plants, oil type AT ABT, avgm. In the atmospheric unit at the plant oil share (option) gas, gasoline fraction (C5- 180), the fraction of diesel fuel (180-350° (C) and the fraction of oil (350° - K.K.) [Akhmetov S.A. Technology of deep processing of oil and gas. Publishing house "Gil" - Ufa - 2002].

Because of the clear separation into fractions of the oil remains up to 5-7% fraction of diesel fuel, reducing start boiling oil (possibly up to 220°).

Furnace commodity fuel oils, for example, M - 100, produced by the method of compounding (mixing) straight-run fuel oil, gas oil fractions of direct distillation and secondary processes, as well as low-viscosity cracking - residue visbreaking process [Handbook edited by Shkolnikov V.M. Fuels, lubricants and technical liquids. The range and application. M: "Techinformi", 1999].

Offer antiseptic viscous oil was obtained as follows.

In the commodity tank pumped calculated the fraction of heavy pyrolysis resin at a temperature of 40-50°C. Then, in the same tank, pumped the estimated fraction of the oil control color. After 30-40 min of sludge required for mutual dissolution (redistribution) uploaded mixing tank is transferred to the circulation scheme: tank → pump → the reservoir. Circulation is performed with the purpose of obtaining a homogeneous mixture of antiseptic viscous. After a specified period of time is circulatio stop, and the mixture advocate for 1.5 to 2.0 hours, and then take the average sample (2 DM3and carry out the analysis on all parameters of quality set by the technical specifications on antiseptic viscous oil - GTK - Century
