Description

[0001] The invention relates to the field of toxic chemical simulators (hereinafter referred to as TC), namely to the use of 1,2-propanediol HOCH2CHOHCH3 as a TC simulator in training in the operation of chemical reconnaissance and control devices based on ion mobility spectrometry and testing their performance.

[0002]

[0003] Chemical contamination simulators are used to train military personnel in operating under chemical contamination conditions and to develop practical skills in operating chemical reconnaissance devices. The criterion for assessing the correct use of chemical reconnaissance devices is their response in the presence of a simulator, which simulates the properties of the chemical properties that cause the indicator effect. When testing the performance of chemical reconnaissance devices, chemical simulators can also be used. In this case, the criterion for assessing the performance of a chemical reconnaissance device is its response in the presence of a simulator.

[0004] A simulation formulation is known for training troops in combat operations under conditions of chemical contamination with blistering agents. A formulation based on 1,2-dibutyldithiaethane is used as a mustard gas simulant. Diesel fuel is used as an organic filler. The simulation formulation was a homogeneous composition containing 10% 1,2-dibutyldithiaethane and 90% diesel fuel. This formulation ensures the activation of only local action chemical reconnaissance (CR) devices using IT-36 indicator elements (indicator tubes) [Patent RU 2260577, Russian Federation, MKP 7C06D 7 / 00. Use of 1,2-dibutyldithiaethane as a mustard gas simulant for training troops in combat operations under conditions of chemical contamination with mustard gas / Alimov N.I., Pavlov A.Yu., Shantrokha A.V., Demidov O.M., Kozyreva A.V., Sorokin A.I., Chernov S.A. Makshakov S.V; applicant and patent holder military unit 61469. - No. 2003133415 / 02; declared 17.11. 2003; published 20.09.2005, Bulletin No. 26. - 4 p.].

[0005] The closest analogue of the claimed invention is a simulation formulation for training specialists of radiation, chemical and biological protection troops, containing the active ingredient - diazinon (24%), organic filler - diesel fuel (54%), organic co-solvent - solvent P-4 (20%) and surfactant - didecyl ether of phosphoric acid (2%) [Patent. RU 2769335, Russian Federation, IPC C06D 7 / 00. Simulation formulation for training specialists of radiation, chemical and biological protection troops / Tagaev V.I., Krasilnikov V.V., Potoropin E.B., Loskutov A.Yu., Serebrennikov B.V., Shlygin P.E.].

[0006] It should be noted that the described (presented) simulation formulas (SR) ensure the actuation of only individual HR devices or are used to test remote HR devices. Currently, there is no production of simulators that ensure the actuation of HR and control devices based on ion mobility spectrometry and their performance testing.

[0007] Thus, it can be noted that at present there is no TX simulator for training military personnel in the operation of chemical reconnaissance and control devices based on ion mobility spectrometry and testing their performance.

[0008] The aim of the invention is to use a non-toxic, accessible organic compound as a TC simulator, which makes it possible to carry out tasks of training military personnel to operate chemical reconnaissance and control devices based on ion mobility spectrometry and testing their performance.

[0009] This goal is achieved by using a compound that mimics the spectral characteristics of the reduced ion mobility of TX in positive or negative polarity. 1,2-propanediol, which has spectral characteristics similar to ammonia at positive polarity, was studied as a simulant in the GS-B and GS-N instruments.

[0010] The essence of the invention lies in the use of 1,2-propanediol as a simulator of the spectral characteristics of the reduced ionic mobility of ammonia in training in the operation of chemical reconnaissance and control devices, as well as in testing their performance.

[0011] The main criterion for choosing a simulator can be considered the most complete match of the reduced ionic mobility of product ions with the simulated TX, which ensures the presence of an indicator effect, as well as its low toxicity and availability.

[0012] The main characteristics of the reduced ion mobility of product ions with the simulated TX are shown in Fig. 1.

[0013] Analysis of the spectra of 1,2-propanediol and ammonia in positive polarity showed the presence of two peaks with a mobility of 2.18 cm 2 / B⋅s and 1.85 cm 2 / B⋅s (ammonia has 2.23 cm 2 / H⋅s, 1.88 cm 2 / В⋅с).

[0014] In addition, 1,2-propanediol is characterized by low toxicity (hazard class 3) and is an accessible organic compound that is widely used as a solvent, as well as a component of pharmaceuticals and cosmetics, and in the food industry [Knunyants I.L. Chemical Encyclopedia, vol. 4., Moscow, 1995. - p. 199].

[0015] Proposed as a simulator, 1,2-propanediol can be used to solve problems of training military personnel in the operation of chemical reconnaissance and control devices, based on ion mobility spectrometry and testing their performance.
