(57) Abstract:The inventive liquid antiseptic for wood treatment on the basis of oily fractions, as the latter contains a mixture distillate fractions of thermal origin, wikipaedia within 325 - 420oWITH+in the following ratio, wt.%: distillate fraction, wikipeida within 325 - 420o20 - 50, distillate fraction, wikipeida within 420oC+50 - 80. table 2. The invention relates to the composition of the oil antiseptic impregnation liquid and can be used for impregnation of wood, in particular for impregnation of wooden sleepers and rails.Known impregnating material which is a mixture of coal oil (coal oil for wood impregnation GOST 2770-74) oil and oil softener (petroleum oil-softner HM-1 TU 38.301.08-31-89), produced 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 20oC 1090 - 1130 kg/m3and oil-softening agent having a density at 20oC 890 - 910 kg/m3using as n the system: the bottom layer is coal oil; the middle layer is water; the upper layer of oil oil-softner. This requires periodic circulation of the mixture according to the scheme: reservoir-pump-reservoir to prevent stratification, which leads to additional energy consumption. It should also be noted that oil oil-softner HM-1 has relatively high values of kinematic viscosity, determined at a temperature of 80oC (6,5 - 8,0 mm2/s), which impairs his penetrating (impregnating) the ability when attempting wood, and consequently, reduces its protective properties.The closest technical solution to the claimed (prototype) is impregnating coal oil coal oil for wood impregnation GOST 2770-74), containing in its composition a relatively narrow oily fraction of thermal origin, representing a mixture of 1-th anthracene fraction (280 - 360oC) and the absorption oil (235 - 300oC).The disadvantages of coal impregnating oils include the following:
1) impregnating coal oil contains up to 0.3 wt.% substances insoluble in toluene (carbenes and carbides) and up to 1.5% of water, which negatively affects the PR process is somatokine), that creates the risk, from the standpoint of sanitary and environmental conditions in the production salepropecia plants;
3) coal sleeper impregnation oil has a relatively high (minus 2 or minus 5oC) pour point, which makes it difficult draining and pumping in winter conditions at lower 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 (Shchelkov A. K. Handbook of koksohimiko. M.: metallurgy, T. 3., 1966).2.5 m3the absorption oil in the mixture injected 7.5 m3first anthracene fraction. After crystallization and centrifugation yield of crystals is 15 - 20 % in the mixture. The chemical composition of coal sleeper impregnation oils are given in table. 1 (Shchelkov SC Guide koksohimiko. M.: metallurgy, T. 3., 1966).The invention solves the problem of increasing the resources sleeper impregnation of the material with a sharp decrease in their toxicity: class 2 (high-risk), class 4 (low hazard).The invention consists in that the known liquid antimateria mixture of distillate fractions of thermal origin, wikipaedia within 325 - 420oC and 420oC+in the following ratio, wt.%:
Distillate fraction, wikipeida within 325 - 420oC - 20 - 50
Distillate fraction, wikipeida within 420oC+- 50 - 80
These fractions was obtained as follows.The vacuum gas oil fraction 300 - 490oC) the primary distillation of crude oil (Gurevich, I. L. the Technology of oil and gas. -M.: Chemistry, h 1, 1972) is subjected to Hydrotreating process to reduce the content of sulfur (Smidovich E. Century Technology processing response and gas, -M.: Chemistry, h 2, 1978). Low sulfur hydrotreated vacuum gas oil (hydrogenation product) is subjected to catalytic cracking in a catalytic cracking unit type G-43-107 (Hajiyev S. N. The cracking of oil fractions over zeolite catalysts. - M. : Chemistry, 1982). The reaction products are subjected to separation in a distillation column with getting gas catalytic cracking and four liquid - gasoline (N. K. - 195oC), light catalytic cracking gas oil (325 - 420oC) and the residue catalytic cracking (420oC+).The starting components and mixtures are given in table. 2.P the shares 325 - 420oC and 420oC+mix in the pipeline by injecting them into marketable tank in a predetermined ratio. Feature in the process of mixing (KNOW-HOW) is the presence of a fine filter on the line faction 420oC+then there is the faction 420oC+before mixing with a grain size of 325 - 420oC necessarily filtered from possibly present therein particles of catalyst dust.Example 1. Heavy catalytic cracking gas oil distillate fractions 325 - 420oC is mixed with the filtered residue catalytic cracking distillate fraction 420oC+in the ratio of 50:50 by weight. The result is an antiseptic liquid GTK-1 with the following parameters (table. 2):

Heavy catalytic cracking gas oil (distillate fraction 325 - 420oC) is mixed with the filtered residue catalytic cracking (distillate fraction 420oC+) in a ratio of 20:80 by weight. The result is an antiseptic liquid GTK-1 with the following indicators table.2:
Kinematic viscosity at 80oC - 4,46 mm2/s
Pour point - -15,8oC
The flash point in an open crucible - 152oC
Density at 20oC - 1,048 g/cm3< / BR>One of the important requirements for protective the oily protective equipment), is the value of the viscosity of the impregnating material. According to GOST 20022.5-93, p. 1.10 kinematic viscosity of protective equipment must be not more than 510-6m2/s at 80oC (not more than 5 mm2/s at 80oC) (Protection of wood. Autoclave impregnation oily protective equipment. GOST 20022.5-93). We offer antiseptic impregnation liquid GTK-1 is the kinematic viscosity depending on the ratio of initial components in the range of 3.25 to 4.46 mm2/with that said about her good penetrating (impregnating) the ability of the impregnation of wood.In addition, impregnating the materials used to protect the wood from defeat her by fungi and bacteria, they themselves must be resilient to such failures. The dependence of microbiological susceptibility of petroleum products from their group and individual hydrocarbon composition (Litvinenko, S. N. Protection of oil products from the action of microorganisms. -M.: Chemistry, 1977). Common microorganisms separate groups of hydrocarbons (ibid, PL. 3) indicates that the oil contain a high percentage of aromatic, especially medium (bicyclic) and heavy (polycyclic), oblad the s from fungi and bacteria. Received at the installation of G-43-107 heavy gas oil catalytic cracking contain 73 - 75% aromatic hydrocarbons (Protection of wood. Autoclave impregnation oily protective equipment. GOST 200225-93), which indicates their high protective properties from the action of microorganisms.Thus, in addition to the existing highly toxic sleeper impregnation oils coal origin we offer liquid antiseptic for wood impregnation GTK-1 contains non-deficient oil fractions, which are by-products of production and related to the 4th class of hazard (low hazard), possessing a high degree of aromaticity, which determines their high antiseptic properties.The invention can be used in railway transport for impregnation of wooden sleepers and rails, construction and other industries for wood impregnation.
