Description

[Detailed description of the invention] Insecticide composition and its manufacturing method Technical field The present invention is useful for pest control such as flies, flies, blackflies, greenhouse whiteflies, cockroaches, and insects. The present invention relates to chemical means of controlling insecticides, and more particularly to insecticide compositions and processes for their production. do.

Background technology The currently used insecticide compositions have the following component ratios (% by mass): Chlorophos 30 Bertolet salt 20 Dicyandiamide 20 Insecticide with (active ingredient) -(1-hydroxy-2゜2.2-)dichloroethyl )-0,O-dimethylphosphonate (chlorophos), potassium chlorate (belt) dicyandiamide, starch and talc. The insecticide composition is 30. 1-2 kg of the insecticide composition into a polyethylene bag, mix the ingredients from (obtained by pre-melting chlorophos) (SU A No. 149648) Specifications).

In addition, the following component ratio (mass%): Hexachlorane 51 Bertolet salt 24 Ammonium hydroxide 10 Anthracene 10 Dicyandiamide 5 - Hexachlorocyclohexane (hexachlorane), Berthollet salt , ammonium hydroxide, anthracene, and dicyandiamide. are known and insecticidal compositions have been prepared as smoke cans.

Said insecticide composition prepared as a smoke can, after mixing the ingredients, mixes the resulting mass. Obtained by charging into stainless steel metal or cardboard boxes (V, S, Jarni Key, “Aerosols in Veterinary Medicine”, 1972, “Koros” Publishing Ha. Us, Moscow, p. 318).

Furthermore, the following component ratios (mass%) Dichlorovos 1-20 Soot 30-70 Exothermic accelerator and oxidizing agent 5-25 Combustion inhibitor 10-30 For example, an insecticide having a 0. O-dimethyl-〇-(2゜2-dichlorovinyl) Phosphate (dichlorovos), pressed or porous soot, exothermic accelerator, e.g. such as manganese dioxide, strontium nitrate, and flame retardants such as silica. Other insecticide compositions consisting of clay, talc or clay are known (insecticide composition things are prepared as smoke cans).

Said insecticide composition prepared as a smoke can, after mixing the ingredients, mixes the resulting mass. Obtained by charging into stainless steel metal or cardboard boxes (JPA No. 56- 75402).

The insecticide composition contains individual chemicals (Bentre salt, dicyandiamide, Spiral, ammonium hydroxide, manganese dioxide, potassium nitrate or barium nitrate IJ um), thus increasing the cost of these compositions.

Moreover, these compositions are multicomponent and usually contain 5 to 7 and more components. Contains minutes. This makes the method of obtaining the pesticide composition more complex and the production raise costs.

Said insecticide compositions prepared as powders or smokes are characterized by low density. , thus reducing the amount of pesticide per unit volume of the pesticide composition; Therefore, it reduces the efficiency of the insecticide composition. Moreover, the importation of known pesticide compositions During shipping and storage, bands of non-uniform density of the composition are formed and this causes irregular pulsating smoke of the powder or smoker when in use. (bouldering). The low density of the composition makes it difficult to store the insecticide composition. resulting in unproductive packaging usage during shipping and transportation. citrus prepared as a smoker Pesticide compositions are stored in special boxes for production (rust-proof metal, cardboard boxes) and also in fumes. requires a fuse for initiation, thus making the insecticide composition more costly. Make it high. Moreover, known insecticide compositions containing hexachlorane are often It ignites during the application process, which makes the composition a fire hazard. Bertolet The use of salt in known pesticide compositions may be due to the ability of Berthollet salt to explode. There are certain risks.

The following component ratio (mass%): Hexachlorane 16 Sawdust 17 Beat 7 Saltpeter 6 - hexachlorane, sawdust, beets, saltpetre, e.g. ammonium nitrate Pesticide compositions consisting of monium, starch, and water are known (the above-mentioned The insect repellent composition is formed into a wax).

This insecticide composition prepared as a wax is manufactured by the following method. Grind: Grind a given portion of hexachlorane with beets and sawdust in a mortar. , the mixture thus obtained is charged into a container. Prepare starch glue, Add saltpeter to starch glue, then add the resulting mass to hexachlorane, beet and sawdust. Mix the resulting mass and put it on the board flatten it as a thin sheet with Form into a wax shape. Dry the wax at a temperature of 50-60°C (V, S. Jarnicki - Aerosols in Veterinary Medicine, 1972, Koros Publishers Ng House, Moscow, p. 319).

Known insecticide compositions prepared as waxes do not contain individual chemicals contains natural substances (beet, sawdust) and mass-produced products (saltpeter); This reduces the cost of this composition.

Still, it is a multi-component insecticide composition (containing 6 components). Besides, this Starch glues used as binders in pesticide compositions meet the Food Starch Standard This increases the cost of the composition. The large amount contained in the insecticide composition The water provides low-intensity smoke, thus increasing the efficacy of the insecticide composition. (including 8 steps). When preparing the insecticide composition, Large amounts of water are used, which complicates drying operations and creates unproductive waste. resulting in energy consumption. Lootsuku are manufactured by hand, which means that they are identical. It does not make it possible to obtain candles with properties.

Moreover, hexachlorane is water-insoluble. Therefore, as a result of hydrophobicity, starch It is virtually impossible to achieve a uniform distribution of hexachlorane in the solution. Ru. This indicates that the insecticidal activity of wax with different contents of active ingredient (insecticide) and Get a candle with a difference. This also means that low This results in an uneven composition of the wax, which results in an uneven pulse of the wax during use. It moves and produces smoke. All of the above are the non-applications of insecticides for practical purposes. It is evidence of sex.

Disclosure of invention It is an object of the present invention to be more effective and when used in combination with low temperature fumes. Characterized by a uniform smoke of and would consist of a small number of ingredients and would not require expensive packaging. , and the process technology and equipment would be obtained by simple methods An object of the present invention is to provide such an insecticide composition.

The purpose of the present invention is to achieve the following component ratio (mass%): beet 30-47 Ammonium nitrate 27-49 Insecticide 1-15 water remainder An insecticide composition consisting of beets having The insecticide composition is formed into briquettes. achieved.

Yet another object of the invention is the use of beets, ammonium nitrate, pesticides and water. In order to obtain an insecticide composition based on 1 mm or less), the ground beets are dried to a residual moisture content of 18-25% by mass and treated with nitric acid. ammonium nitrate to water mass ratio of 80 at a temperature of 80-90°C ~85: Aqueous solution of ammonium nitrate by dissolving in water at 20~15 Prepare the prepared ammonium nitrate aqueous solution with ground beets and beets vs. ammonium nitrate. Mix the monium aqueous solution at a mass ratio of 1.0:0.7 to 1.7, and obtain the The resulting mass is briquette-ized at 60-85°C, and the resulting briquettes are Dry to a residual moisture content of 14 to 20% by mass at a temperature of 60°C or lower, and mix into dry briquettes. Dissolution of the pesticide in a highly volatile organic solvent based on 1-15% of the pesticide from the weight of the packet. An insecticide characterized by impregnating the briquette with a liquid and removing the organic solvent from the impregnated briquette. An object of the present invention is to provide a method for obtaining a pharmaceutical composition.

To increase the strength of briquettes, before mixing with ammonium nitrate aqueous solution , it is recommended to heat the ground dried beets to a temperature of 45-55 °C.

Known insecticide set prepared by powdering according to SU A 149648 Product, JP A No. 56-75402 and v. S. Jarnicki “In Veterinary Medicine” Aerosol J, 1972, Koros Publishing House, Moscow, compared to known insecticide compositions prepared as smoke cans according to page 318. The proposed insecticide composition prepared as a packet has a high density (1.7-2.2 g/ It has a stiffness. Thus, in the same volume as known insecticide compositions, It is now possible to introduce larger amounts of insecticide into the briquette formulation, thus reducing the It becomes possible to increase the efficacy of insecticide compositions. Briquettes are made by high strength (compressive strength is 20-55 kg/c). High strength briquette The beets are processed with ammonium nitrate in combination with subsequent pressing into briquettes. Depending on the conditions of mixing with the ammonium nitrate solution (the amount of beet, ammonium nitrate, and water) and the temperature of the aqueous ammonium nitrate solution). Briquette formation Ammonium nitrate as a component acts as a binder and an oxidizing agent. Be Compared to Lutre salt, ammonium nitrate has lower decomposition temperature, better solubility in water and is not explosive under pesticide briquette preparation conditions.

During transportation and storage, briquettes are stable and their properties (density, strength) degree, thermal sublimation degree, etc.). Uniform density throughout the briquettes Ensures uniform intensity of briquette smoke during use. In the proposed insecticide composition The assembly of the components and the physical properties of the briquettes are determined by 00-250℃). Low-temperature briquette smoke can cause ignition during the application process. Eliminate and make fire retardant. Moreover, low-temperature briquette fumes are caused by the heat of insecticides. therefore, the insecticide complex as a possible consequence of the action of this factor. Eliminate loss of product efficiency.

The proposed insecticide briquettes are simple in composition and do not contain individual chemicals. However, widely available natural substances (beet) and cheap mass-produced technological products (vitreous ammonium acid).

Besides, briquettes with high strength can be used in expensive hard packaging (rust-proof metal and (cardboard box) is not required. They are packaged in polyethylene film to prevent atmospheric moisture. Gives a barrier of briquettes. Use cheap packaging instead of expensive packaging This gives additional economic benefits.

V., S. Jarniky, Aerosols in Veterinary Medicine, 1972, Koros Pub. Already prepared as lodsk according to Shing House, Moscow, page 319 The proposed insecticide composition prepared by briquetting when compared with known insecticide compositions. Contains a small number of ingredients (beet, ammonium nitrate, pesticide, water). On top of that , in the proposed insecticide composition, ammonium nitrate is added to the starch glue. Instead, it is used as a binder (ammonium nitrate is also an oxidizing agent) and is This reduces the cost of pesticide compositions.

The moisture in the proposed insecticide composition prepared as briquettes is Compared to the above-mentioned known insecticide compositions prepared, this It increases the smoke intensity and makes the application process more efficient. briquet The use of small amounts of water during the preparation of the proposed insecticide composition as a briquette This makes it possible to drastically reduce energy consumption for drying.

The proposed insecticide composition can be obtained by simple methods in terms of technology and equipment. and all operations can be easily automated. Ammonium nitrate as a solution briquettes for use in and also for impregnating the briquettes with solutions of pesticides. Uniformity of the composition is given throughout their entire height and therefore uniform smoke , achieved when applying briquettes.

The insecticide composition is easy to apply and does not require special equipment or skilled personnel. stomach. Any open flame source can be used as an initiator for fuming the pesticide composition; The need to use hinnies as in is avoided.

The proposed insecticide composition can be used in indoor spaces (e.g. storage facilities, greenhouses, industrial and Auxiliary livestock breeding areas, damp flooded basements of residential structures and industrial buildings, treatment of outdoor spaces (e.g. ranches, forests, plantations) It can be effectively used for both garden and garden treatment.

Depending on the end use, the insecticide composition can be produced in different geometrical forms (cylindrical, cubic, etc.) Can be prepared as briquettes of different masses (from Ig to 1-3 kg) with .

As mentioned above, the proposed insecticide composition contains 30-47% by weight of beets, ammonium nitrate, It consists of 27-49% by mass of monium, 1-15% by mass of insecticide, and the remainder is 100% by mass. % water.

Beets containing less than 30% by mass and more than 49% by mass of ammonium nitrate It is not reasonable to use insecticidal compositions. The reason is that in this case, This is because excess water will be included in the production of the briquettes. Pressing During (briquetting), squeezing of ammonium nitrate solution from the pressed mass occurs. This may lead to unproductive consumption of the salt. As a result of the press, high It has a high moisture content and requires a long drying time, and a layer of ammonium nitrate is applied on the surface. The briquettes are obtained and fit to ignite only from high temperature flame sources. There is.

Beet content greater than 47% by weight and ammonium nitrate content less than 27% by weight It is not recommended to use insecticide compositions with The reason is that ammonium nitrate The amount of solution will be insufficient for uniform wetting of all the beet salt and therefore This is because the amount would be insufficient to obtain strong briquettes.

It is not recommended to use insecticide compositions having an insecticide content of less than 1%.

The reason is that the insecticide composition does not give control of insects within the scope of aerosol cloud propagation. That's because it would be.

It is not recommended to use pesticide compositions with a pesticide content of more than 15% by weight. Not possible. The reason is that not all the mass of pesticide sublimes, and this This is because it results in unproductive loss of pesticides.

When mixing beets with aqueous ammonium nitrate solution according to the method proposed here The mass ratio of beets to ammonium nitrate aqueous solution is 1.0:0.7 to 1, respectively. ．． Equal to 7. of beets and ammonium nitrate solution in proportions exceeding the above limits. Use will result in the aforementioned results.

As mentioned above, the beets are ground into the resulting granules before mixing with the aqueous ammonium nitrate solution. After grinding to particles with a size of 1■■ or less, until the residual moisture is reduced to 18 to 25% by mass. ,dry.

It is not recommended to grind the beets to a particle size larger than 1 mm. So The reason is that the strength of the briquettes will decrease.

It is not recommended to dry ground beets to a residual moisture content of less than 18% by weight. The reason The reason is that it involves unproductive consumption of energy. 25% by mass of crushed beets It is not good practice to dry to too much residual moisture. The reason is, The resulting beets contain an excess amount of water, which causes the beets to become diluted with ammonium nitrate. After mixing with the solution will result in the squeezing of ammonium nitrate from the pressed mass. It's your body.

To prepare an aqueous ammonium nitrate solution, the salt and water are combined as described above. , the mass ratio is 80-85:20-15, and the salt is dissolved at 80-90℃. Perform at temperature. As a result, it has a concentration of 80-85% and a temperature of 80-90°C. An aqueous solution of ammonium nitrate is obtained. Then, the obtained ammonium nitrate The aqueous solution is mixed with the beets.

It is prohibited to use ammonium nitrate aqueous solution with a concentration of less than 80% in the mixing stage. Not recommended. The reason for this is that squeezing out the ammonium nitrate solution from the pressed mass produces This is because an ammonium nitrate layer is formed on the surface of the dried briquettes.

Using an aqueous ammonium nitrate solution with a concentration of more than 85% in the mixing stage is not recommended. The reason is that there will be insufficient moistening of the beets and that Well, the strength of the briquettes would be drastically reduced.

Preparation of ammonium nitrate aqueous solution at a temperature of 80-90 ° C is equal to 80-85% determined by the need to obtain a salt solution with a concentration.

The mass obtained as a result of mixing beets with aqueous ammonium nitrate solution is 60-8 Press at a temperature of 5°C. It is not recommended to press the mass at temperatures below 60°C. stomach.

The reason is that the strength of the resulting briquettes will be reduced. 8 pieces Pressing at temperatures higher than 5°C is not recommended. The reason is that the pressed mass ignites. This is because there is a possibility that

The briquettes obtained by pressing the mass are dried at temperatures below 60 °C. Ru. At temperatures higher than 60°C, the formation of flavours occurs on the surface of the briquettes. observed, this reduces the strength.

Said drying of the briquettes is carried out to the point where a value of 14-20% by weight of residual moisture is reached. Ru. It is not recommended to dry briquettes to a residual moisture content of less than 14% by mass. Not possible. The reason seems to be that there is a possibility of the briquettes catching fire during use. Ru. It is not recommended to dry briquettes to a residual moisture content of more than 20%. do not have. The reason is that in this case it is more difficult to start smoking the briquettes. This is because it is difficult.

The ground dried beets were brought to a temperature of 45-55°C before mixing with the aqueous ammonium nitrate solution. Heating is recommended.

This increases the strength of the briquettes. Bring beets to a temperature higher than 55°C Heating is not recommended.

The reason is that beets that have been heated to a temperature higher than 55°C are heated to a temperature of 80-90°C. When mixed with ammonium nitrate solution, the resulting mass may ignite This is because it is heated to a temperature that produces Heat the beets to a temperature below 45°C. It is not recommended to do so. The reason is that this results in a substantial increase in the strength of the briquettes. This is because it does not bring about

The proposed insecticide composition prepared as briquettes is obtained in the following manner.

In a crusher, for example a hammer crusher, the beets are crushed into pieces of one size or less. Particles having the following properties are obtained. The ground beets are then prepared with a residual moisture content of 48-25% by mass. to dry.

An 80-85% aqueous solution of ammonium nitrate is prepared by adding ammonium nitrate at 80-90°C. Ammonium nitrate to water mass ratio 80-85: 20-]5. Prepared by

Prepared ammonium nitrate aqueous solution is beat vs. ammonium nitrate in a mixer. Mix with crushed dried beets at a mass ratio of 1.0 = 0.7 to 1.7. This is carried out until a mass of homogeneous composition is produced. Increasing the strength of the resulting briquettes In order to obtain Heating to 55°C is recommended.

The resulting mass of mixing beets with an aqueous ammonium nitrate solution is 60-8 Press at 5°C to make briquettes. The temperature of the resulting briquettes does not exceed 60°C. Dry at a temperature of 14-20 to a residual moisture content of 2%. High volatility in dry briquettes Impregnation with a solution of insecticide in a machine solvent (1-15% insecticide relative to the briquette mass) Ru. Insecticides (active ingredients) include, for example, organic chlorine, organic phosphorous compound, carbame birethroid, i.e. (1-hydroxy-2,2,2-trichloroethyl >-0,0-dimethylphosphonate, N-methyl-〇-(naphthyl-1)carba Mate, 0. O-dimethyl-〇-(2,2-dichlorovinyl)phosphate, ( ±)-cis, trans-3-(2,2-dichlorovinyl)-2,2-dimethylsil 3-phenoxybenzyl ester of clopropanecarboxylic acid, N,N-di(2 , 4-xylyliminomethyl) methylamine, etc. can be used.

Highly volatile organic solvents such as acetone, petroleum ether, diethyl ether , n-hexane can be used.

Highly volatile organic solvents can be removed from impregnated briquettes in an exhaust hood at room temperature, for example. Ru.

Insecticide briquettes obtained according to the described method were packed in polyethylene film. , stored indoors in bags or transported to the application site.

The proposed insecticide composition in the form of briquettes can be used to control pests, such as flies, flies, blackflies, and insects. Used in medical sanitation, veterinary medicine and agriculture for the control of whiteflies, greenhouse whiteflies etc. can. The pesticide composition can be used in different homes (greenhouses, warehouses, industrial and auxiliary animal breeding). Seed spaces, damp flooded basements of residential and industrial buildings, tourist tents , temporary housing for anglers, woodcutters, hunters, etc.) as well as outdoor areas (e.g. It can be used to treat ranches, pastures, forest areas, planchy grasses). Briquette The insecticide composition in the form of As a result of its formation, it produces an insecticidal effect.

Before treating the house with the proposed insecticide composition, close the windows, doors, ventilation holes, i.e. , it is recommended to give as much sealing of the house as possible. Airtightness of houses to be treated This makes it possible to increase the effectiveness of pest control.

When treating a house with a large space, the treatment of the space is carried out from several points. giving an even distribution of the briquettes within the briquettes, thus ensuring that the insecticide ( Facilitates the filling of houses with insecticide aerosols while creating a high concentration of active ingredients do.

Early morning or late afternoon when there is no vertical air movement and horizontal movement is minimal. It is recommended that outdoor spaces be treated at the earliest. Maximum from pesticide treatment effect is achieved under such conditions.

Pesticide compositions prepared as briquettes contain the necessary used in large quantities. The number of briquettes used depends on the type of active ingredient (insecticide) and the briquette. its concentration in the rickets, the pests to be controlled, the characteristics of the house to be treated (room length and (the relationship between width and height) etc.

Insecticide briquettes intended for the treatment of enclosed houses or open spaces must be packaged before use. Should be free from cage (polyethylene film) and briquette The initiation of smoke is carried out from an open flame source, for example a combustion match.

In the case of house treatment, the house should remain closed (unexposed) for 15 to 60 minutes. The time will depend on the type of active ingredient incorporated into the briquette composition and the number of insects under control. (depending on the type), then the house is aerated and the ash from the burning of the briquettes is Remove from house.
