FIELD: chemistry. SUBSTANCE: imitator of a toxic chemical is an organophosphorus substance in aqueous media. The substance can be use to imitate contamination of water bodies when simulating the process of spreading of soman in fresh water rivers taking into account specific morphological features of separate parts of their channel and to determine the behaviour of spreading in time and degree of dilution of the contaminated region at a given distance from the source. EFFECT: possibility of using non-toxic and readily available soman imitator. 1 tbl
The invention relates to a simulator of a toxic chemical (TX), in particular organophosphorus substances (FAUVE), namely the use of the substance N,N-diethylaniline (N,N-diethylaminobenzoic C6H5N(C2H5)2as the simulator pinoylibog ester foramerica methylphosphonic acid (soman) while studying the dynamics of spread of soman in flowing and stagnant water. Means of simulation of chemical contamination are used for training the troops to action in terms of chemical contamination, optical infrared remote tools chemical reconnaissance, control and checking their health, as well as practical skills with instruments chemical reconnaissance. The criterion for the correct use of the devices chemical reconnaissance are tripping in the presence of a simulator, which simulates the properties of toxic substances that cause a display effect. The criterion for assessing the efficiency of the device chemical reconnaissance in this case, it is also triggered in the presence of the simulator. In the literature there is information about using dimethylmethylphosphonate (DMMP) and sulphur hexafluoride (SF6as imitators FAUVE in the development and testing of lidar systems for remote detection of chemical ZAR is ment [Erin A.I., Talberg SHOSTAKOVICH, Malyshev V.A., Gatenby VA Modern principles of organization and equipment equipment bodies chemical reconnaissance and chemical control (review) // Civil defense abroad. - 1991. No. 5, 6. - P.39-44]. However, these compounds are used to simulate the optical characteristics of the FAUVE type G only in a narrow spectral range corresponding to the operating spectral range of the active lidar systems based on CO2lasers and only in the atmosphere. At the same time, the above simulators FAUVE are toxic and not readily available compounds. Known organic compounds used as imitators of the FAUVE trimethylphosphate and dimethylsulfoxide, with close to FAUVE spectral characteristics in the middle infrared range in the form of vapour [RF Patent №2261858, IPC7C07C 317/04, G01N 21/35, 10.10.2005]. However, these compounds are used in the middle infrared range in the vaporous state and simulate only the spectral characteristics of the samples were acquired in the atmosphere. The use of the above compounds as imitators soman impossible in the conditions of the aquatic environment because they do not meet the basic criterion of solubility: trimethylphosphate dimethyl sulfoxide dimethylmethylphosphonate (DMMP) and sulphur hexafluoride (SF6). In addition, the manner in which the atmosphere between differs from the behavior in aqueous media, where multicomponent formulation splits into its components in accordance with the values of solubility. Thus, it can be noted that at present there is no simulator soman for laboratory study the dynamics of the spread of soman and products of its degradation of the aquatic environment in flowing and stagnant water. The aim of the invention is the use of non-toxic and available substance N,N-diethylaniline as simulator soman, allowing to investigate the dynamics of the spread of it in running and stagnant water. This goal is achieved by the use of substances with similar soman physical characteristics in the aquatic environment. As the simulator was investigated N,N-diethylaniline with close to soman values of the physical parameters. The main criteria for selection of simulation formulations can be considered the most complete coincidence of the values of solubility, viscosity and density of the simulator and toxic chemical (soman); the possibility to quantify at low concentrations; low toxicity; low cost and availability. From a number of investigated possible imitators are most acceptable for use in the aquatic environment is N,N-diethylaniline. Its main physical characteristics in comparison with soman performance is aulani in the table.
From the data presented in the table it follows that the total estimated parameters N,N-diethylaniline is closest to the soman physical characteristics (solubility, density and viscosity have the same values) and therefore the most suitable for simulation of soman in the aquatic environment. In addition, N,N-diethylaniline is non-toxic and available inorganic compound which is widely applied in the I for the synthesis of diethylamine, Akrihin and novocaine [Chemical encyclopedic dictionary. Edited Elecronica. - M.: Great Russian encyclopedia, 2003. - S. Quick reference for chemistry / edited Oddcomment. - Kiev: Naukova Dumka. 1974. - S]. Proposed as simulator N,N-diethylaniline can be applied to solve problems in the simulation of chemical contamination of water bodies: when modeling the distribution process soman in beds of freshwater rivers, when determining the temporal dynamics of the distribution of the area of contamination, determining the degree of dilution of the area of contamination relative to the initial concentration at a given distance from the source, when modeling the spread of soman on the given section of the channel, taking into account its specific morphological features. The use of N,N-diethylaniline as simulator soman while studying the dynamics of its distribution in the aquatic environment of flowing and stagnant water bodies in the laboratory.
