Description

The invention relates to simulators of toxic substances (OB), in particular organophosphorus toxic substances (FOV), namely the use of formulations based on O, O-diethyl-O- (3,4,5-trichlorophenyl) phosphate (I) as a simulator FOV during the training of troops.

Chemical contamination simulation tools are used to train military personnel in practical skills of working with chemical reconnaissance devices, to overcome infected areas, and to carry out the degassing of weapons and military equipment.

Used to date, simulators of OM, designed to infect the area, weapons, military equipment and skin protection, are a mixture of neutral substances (fillers) with substances that have a strong irritating effect on the body (chloropicrin, chloroacetophenone). These compounds irritate the mucous membrane of the eyes and human skin, which determines the necessity of using personal protective equipment by the training personnel. At the same time, such formulations do not cause a similar OB analytical effect and, therefore, cannot be used in training troops to work with chemical reconnaissance and control devices.

Currently, work is underway to search for FOV simulators that can be used in the development and testing of protective equipment, indicators and control, special processing equipment. These compounds, along with satisfactory modeling of the physicochemical properties of FOV, should not be highly toxic, because FOM simulators used for training personnel should primarily ensure the highest level of safety for personnel and the environment.

Thus, it can be noted that at present there is no universal and safe FOB simulator for training personnel of troops in combat operations under conditions of chemical infection.

The closest analogue of the claimed invention for the same purpose in terms of features is a simulation formulation for training troops in combat operations under conditions of chemical infection with organophosphorus toxic agents, containing 30-35% of dioctyl phthalate, 65-70% of diphenyloxyphosphate or diphenyloctyl phthalate, up to 0.5% additive (turpentine or castor oil, etc.) [British Patent No. 1093382, 11.29.1967, IPC 7 C 06 D 7/00, 2 l.]. At the same time, the indicator tubes of chemical reconnaissance devices do not determine this simulation formulation.

An object of the invention is the development of a universal and safe simulator of FOV, which allows to perform all tasks of training military personnel in combat operations in the conditions of chemical infection.

This task is achieved by the use of formulations based on an organic filler and an active component that simulates FOV. It is proposed to use O, O-diethyl-O- (3,4,5-trichlorophenyl) phosphate as the active ingredient. This compound effectively affects cholinesterase, which leads to the presence of indicative (analytical) effect. At the same time, the characteristics of metabolism in the body make it low-toxic for warm-blooded. As an organic filler to create a homogeneous composition, it is proposed to use affordable, cheap, safe, easily recyclable organic solvents.

In general terms, the criteria for choosing the composition of the simulation formulation can be formulated as follows:

- the presence of an indication effect (triggering of chemical reconnaissance devices);

- degassing by staff, designed for the degassing of weapons and military equipment;

- homogeneity of the composition;

- cost characteristics of the composition.

When choosing compounds acceptable for these purposes, first of all, it is necessary to focus on the presence of an indication effect (for FOV, this is inhibition of cholinesterase).

Antiacetylcholinesterase activity of O, O-diethyl-O- (3,4,5-trichlorophenyl) phosphate in comparison with sarin and soman are presented in table 1.

From the data presented in table 1, it follows that O, O-diethyl-O- (3,4,5-trichlorophenyl) phosphate has indices of antiacetylcholinesterase activity that are close to regular FOV.

Based on compounds having a structure close to O, O-diethyl-O- (3,4,5-trichlorophenyl) phosphate, formulations were prepared containing 10 vol.% Active ingredient and 90 vol.% Diesel fuel as a filler.

The studied formulations were homogeneous mixtures. Diesel fuel as a filler was proposed in connection with its low cost, safety and widespread use in the daily activities of the troops.

These formulations were investigated on the indicator elements of chemical reconnaissance devices. The research results are presented in table 2.

The data obtained indicate that the most acceptable results were obtained for the formulation based on O, O-diethyl-O- (3,4,5-trichlorophenyl) phosphate.

Toxicological studies of the recipe revealed that it belongs to the third class of toxicity (LD ₅₀ = 104.7 mg / kg intravenously, white mice; 323.6 mg / kg orally, white mice), which makes it possible to use it for training personnel.

The proposed simulation formulation based on O, O-diethyl-O- (3,4,5-trichlorophenyl) phosphate can be used to solve all the problems of training military personnel in combat operations under conditions of chemical contamination.
