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

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

However, in the manufacture of the working mixture, consisting of coal oil having a density at 20°within 1090-1130 kg/m3and oil-softener HM-1 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 butter - softening agent. To maintain in the tank of a homogeneous system, it is necessary to carry out continuous circulation of the mixture according to the scheme: tank→pump→tank, which will require high energy costs and will affect the cost of the product.

Known coal sleeper impregnation oil (GOST 2270-74), containing in its composition a narrow oily fraction of thermal origin and represents the way the first mixture of the first anthracene fraction (280-360° C) and the fraction of absorbing oil (235-300° (C) [Handbook of koksohimiko Vol.3, Ed. Engineer A.K. Silks. - 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% substances insoluble in toluene (carboids and carbenes) and up to 1.5% of water, which negatively affects the process of impregnation of the wood, reducing the total absorption antiseptic wood.

2. Toxicity of coal sleeper impregnation oil refers to the 2nd class (highly hazardous), which creates an increased danger from the point of view of the sanitary-hygienic and ecological status sleeper impregnation plants. Coal oil has a high degree of cancerogenity.

3. Coal sleeper impregnation oil is prepared by mixing and co-crystallization of the first anthracene fraction and absorption oil with subsequent separation of the crystals in the centrifuge. The density of the crystals cannot be separated.

4. A significant drawback of coal sleeper impregnation oil is its tendency to sedimentation during storage and transport, which leads to the necessity of "erosion of sediment in tank wagons and irrecoverable loss of storage in the cut is rowrah.

5. Coal sleeper impregnation oil (creosote) has a sharp, unpleasant and very long lasting smell, which negatively affects staff sleeper impregnation plants and plant operators using impregnated sleepers when laying them on the railroad tracks.

The closest technical solution to the claimed invention is antiseptic liquid for impregnation of wood (RF patent No. 2065356, UK 3/50 from 20.08.1996, containing 80-85% oily fractions of thermal cracking (thermovisual), wikipaedia within 220-450°and 15-20% of the solvent - hydrocarbon fraction of catalytic cracking, wikipeida within 180-340°C.

The disadvantages of the known antiseptic liquids include the following :

1. Not enough high fungicidal toxicity of this fluid against the fungi and bacteria that destroy wood sleepers and rails.

2. Using as diluent a large number (15-20%) deficient fraction of the hydrocarbon fractions of catalytic cracking, wikipeida within 180-340°S, which also has a low (below 80°C) flash point.

The goal of the project is achieved in that the antiseptic oil for impregnation of wood with aromatic solvent containing oil fraction thermal gasoil and the romantic solvent, characterized in that the oily fractions thermal oil it contains a mixture of oily fractions of heavy oil catalytic cracking, wikipaedia within 300-450° (50-90 wt.%) and oily fractions of heavy oil thermal cracking, wikipaedia within 200-400° (10-50 wt%), and as an aromatic solvent contains a concentrate of aromatic hydrocarbons With9-C11obtained in the process of selective extraction catalyzate formed after catalytic reforming of gasoline taken in the following ratio, wt.%:

In the capacity of the unctuous fractions of the thermocatalytic gas-oil it contains the mixture of the unctuous fractions of the heavy gas-oil of the catalytic cracking boiling within the limits of 300-450°С - 50-90 mass % and the unctuous fractions of the heavy gas-oil of the thermal cracking, boiling within the limits of 200-400°С - 10-50 mass %; and in the capacity of the aromatic solvent it contains the concentrate of the aromatic hydrocarbons C9 - C11 produced in the process of the selective extraction of the catalysate formed after the catalytic reforming of the benzine taken in the ratio of 70-95 mass % of the indicated mixture of the heavy gas-oils of the catalytic and the thermal cracking and 5-30 mass % of the indicated aromatic solvent. The technical result of the invention is expansion of the resources of the unctuous antiseptics for impregnation of the wood on the basis of the highly-viscous unctuous fractions of the heavy gas-oil of the thermal cracking and the heavy gas-oil of the catalytic cracking ensuring the good penetrating (saturating) capability and having the lower chilling temperature.

EFFECT: the invention ensures expansion of the resources of the unctuous antiseptics for impregnation of the wood on the basis of the highly-viscous unctuous fractions of the heavy gas-oil of the thermal cracking and the heavy gas-oil of the catalytic cracking providing the good penetrating (saturating) capability and having the lower chilling temperature.
