    The invention relates to the field of wood processing, in particular to means of chemical processing of wood.
    The purpose of the invention is to increase the effectiveness of the composition.
    A large amount of halogenated stochol is used to protect the wood, as well as
    microbial refining agents and preservative agents.
    Halogenated phenols have significant deficiencies in their spectrum of activity, are unsuitable for some substrates, show too high levels of toxicity, or have an unpleasant odor. For these reasons, these phenols

    difficult to use, require a large dosage, or for other reasons unsuitable or partially suitable for practical use. For example, pentachlorophenol, used as a means of protecting against mold and rotting of textiles, is characterized by insufficient light resistance and toxic toxicity.
    As antifungal medium s: twa dl. 1 - (- A-chlorophenoxy) -1-imtzd-azolyl- (1) -3, 3-dimethylbutan-2-one is also used to protect materials. However, this agent exhibits unsatisfactory protective activity, especially with regard to protecting textiles from the appearance of mold and rotting.
    According to the invention, to protect the wood from damage, use a composition containing as active substance a compound of the formula
     f-N | 1 | N X N-CH
    where R is a hydrogen atom or Q kil.
    The composition contains 0.125 to 20% of the active substance, and as a carrier a 50% aqueous solution of methanol, or a mixture of 5% dibutyl phthalate, 10% n-butyl ether of glycolic acid and white spirit, or a mixture of 40% ethylene glycol monoethyl ether, 10% N, N-dimethylformamide and xylene, or a mixture of 20% cyclohexanone, 2.5% acetic acid and toluene or xylene.
    The wood used is logs, timber, rail sleepers, telephone poles, wooden fences, wood coverings, wicker products made of wood materials, plywood, boards, sawn timber bridges or wood materials used in the construction of houses.
    The active compounds can be used with additives either alone or in combination with other suitable carriers and / or other additives, - 10

    kami. Suitable carriers and additives can be solids or liquids and can be used in formulation technology of natural origin or regenerated inorganic substances, in addition, they can be solvents, dispersants, emulsifiers, wetting agents, agents that help retain the applied formulation. - on the surface to be treated, thickeners, binding agents.
    The compounds exhibit good solubility in organic solvents, as well as in carrier gases, etc., using aerosol packs. In this connection, their lack of color and smell is of great practical importance.
    Protected material treated with an agent must contain an active ingredient of 2000-15000 ppm.
    The agents are preferably used in the form of solutions. For this, the active component is dissolved in suitable organic solvents or mixtures of solvents, in some cases taken in a mixture with water. Forms for applying active ingredients may follow conventional formulations. Means for protecting textiles should contain the active ingredients in finely divided form.
    Solutions can be applied for application, dispersions and emulsions of the active ingredients. For example, node dispersions can be made from pastes or concentrates and used in liquid form or as an aerosol. Processing is advisable to be carried out at a temperature of 10-100 ° C, preferably 4g, at room temperature.
    Due to its good solubility in organic solvents, the active substances are used for application in non-aqueous media. Thus, the materials to be protected can be easily impregnated with solutions. As organic solvents, it is possible to use aromatic and aliphatic hydrocarbons, their chlorinated derivatives, amides of acids, mineral oils, alcohols, ethers, glycol ethers, for example methylenechloride, propylene glycol, methoxyethanol, ethoxyethanol, K, H-di30

     Compositions for treatment contain, depending on their intended use, 0.1-50 g (preferably 1-30 g) of active substance per liter.
    Example I. Fagus syliatica pieces of wood, 6 cm in size, dried in an oven for 18 hours, then cooled in a desiccator and weighed. Test pieces are placed on the bottom of Petri dishes, which are placed in a vacuum desiccator. The pressure is reduced to 40 mbar by means of a water-jet pump. The bars are impregnated with a soluble solution having a concentration of 0.15, 10, or 20% of the active component in a 50% aqueous solution of methanol. The impregnation is carried out through a tube inserted at the bottom of the Petri dish. After the bars have been sufficiently exposed to vacuum, Petri dishes are removed from the desiccator and left for 2 hours to saturate the bars. The control bars are treated in the same way with a 50% aqueous solution of methanol. The bars are then washed with filter paper, weighed and the amount of trapped test compound is calculated. For each of the compounds and for each of the concentrations, four bars are used.
    The bars are then sterilized with steam at SO with three times for 5 minutes. After 6 sous after treatment, the bars were transferred to Petri dishes containing agar-malt nutrient medium, monoculated 20 days before the test with Coriolus versicolor. Two bars (one processed, the other control) are placed on a stainless steel frame in a Petri dish. The test bars are exposed to fungi for 8 weeks. at 25 ° C, in order to avoid drying, Petri dishes are placed in a plastic bag,



    The condition of the bars is assessed visually according to the following grading system: Q, - no exposure to microorganisms, I - minor exposure to microorganisms, 2, - moderate exposure, and 3. - strong exposure to microorganisms.

    Example 3. Wood pine bars measuring 5x2.5x0.5 cm were placed in an autoclave for 20 minutes, after which they were dried for 19.5 hours at 100-llOt. Then they were allowed to cool in a desiccator and then weighed (initial dry weight )
    1 ml of a 0.125% solution of the test compound in a mixture of methanol and water (1: 1) is evenly distributed 5 over the surface of the wood bars, with the result that the final concentration of the active substance on the wood is equal to 2 kg per 1 m. Bars of wood treated with an aqueous solution of methanol (1: 1) are used as control samples.
    The bars are dried in a laminar air drying cabinet. The solvent is distilled off in a drying oven for 3 hours.
    These bars are then placed in Petri dishes containing agar-malt medium, on which, 8 days before the test, Coniphora puteana culture was sown. Two bars treated with the active ingredient at the same concentration are placed in a Petri dish on a small stainless steel frame to ensure contact with aerial mycelium of the fungal culture and eliminate contact with the agar culture medium. Bars are exposed to fungal microorganisms for 8 weeks. at 25 C. Then they are cleaned of the mycelium adhering to them, dried in a drying cabinet at 100-110 C for 19.5 hours and then dried in air.
    The test results for example 3 are given in table. 3
    Example 4. May 6 is a soluble concentrate prepared by mixing the following substances, including:
    Active ingredient 20 Ethylene glycol monoethyl ether, 40 N, N-dimethylformamide10 Xylene 30 To this concentrate, oil is mixed with a cutting operation at a concentration of 0.1%. In this way, a protective action against damage caused by microorganisms is achieved.
    The test blocks are dried in an oven at 100-1 ° C for 18 hours, cooled in a desiccator and weighed to determine the initial dry weight. The test blocks are weighed on the bottom of the Petri dishes and placed in a vacuum desiccator. The pressure is reduced to 40 mbar using a water-jet pump. Then the blocks are passed through with a preservative solution through a tube drawn to the Petri dish. After this, as the block is well covered, the vacuum is turned off. The petri dishes are removed from the desiccator and left for 3 hours in order to saturate these blocks and achieve wood sterilization with 50%
    tanol solutions. Control locks are treated in a similar manner by impregnation with 50% ethyl alcohol.
    All operations are carried out in a laminar air flow to ensure sterile conditions.
    Blocks are tamped with sterile plastic paper and weighed to the nearest centigram (weight after treatment). The amount of preservative absorbed by the blocks is easily calculated — a fuse in the wood.
    At each concentration, for each compound, four to six blocks are dried at room temperature. Wood blocks treated with compounds 3 and 4 are dried for 4 days. and sterilization, coziness, in an open steam sterilizer: three consecutive treatments for 20 minutes at intervals of 24 hours. Due to the possible decomposition of pentachlorophenol and sodium heat treatment.
