Problems solved by technology

[0005] Although the United States, the United Kingdom and Israel have also prepared some simulants of liquid explosives, their appearance, shape and density are similar to real explosives, and their atomic numbers are also similar to real explosives, but they are different in element composition, element percentage content and color. For real explosives, it cannot achieve the desired effect of full simulation. It can only be called ray-level simulation, which affects the accuracy of the security detector to identify substances.
But so far, no nitrobenzene simulants and related information have been retrieved

Embodiment 1

[0028] Take a 300ml clean Erlenmeyer flask, put it into a magnet for stirring, first add 19.27g of accurately measured lactic acid, start stirring, adjust the stirring speed to 600r / min, and add 55.93g of 2,4-toluene diisocyanate while stirring; Turn on the temperature rise, and when the temperature rises to 50°C, keep the constant temperature and add 24.80g of phthalimide; after the addition is completed, adjust the stirring speed to 800r / min, and continue stirring for 30min to completely dissolve the phthalimide, and cool to After room temperature, the material is discharged to obtain a liquid simulant of nitrobenzene. The determined element percentage content is: C 59.01%, H 4.05%, O 25.68%, N 11.26%, the error is within ± 2%, and its atomic number is calculated to be equal to that of nitrobenzene. Compared with nitrobenzene, the atomic number The ordinal number is equal, the color and appearance are the same, and the element percentage is within the error range, which is c...

Embodiment 2

[0030] Take a 300ml clean Erlenmeyer flask, put it into a magnet for stirring, first add 22.94g of dimethyl malonate accurately measured, start stirring, adjust the stirring speed to 600r / min, add 70.61g of 2,4-toluene diisocyanate; add After the completion, start the temperature rise. When the temperature rises to 80°C, add (p)benzoquinone 6.45g at a constant temperature. After the addition, adjust the stirring speed to 800r / min, and continue stirring for 30min to completely dissolve the solid matter. Cool to room temperature and discharge , to obtain liquid simulants of nitrobenzene. The determined element percentage content is: C 58.84%, H 4.12%, O 25.72%, N 11.32%, the error is within ± 2%, and its atomic number is calculated to be equal to that of nitrobenzene. Compared with nitrobenzene, the atomic number The ordinal number is equal, the color and appearance are the same, and the element percentage is within the error range, which is consistent with nitrobenzene.

Abstract

The invention relates to a nitrobenzene full-simulation explosive simulant, belonging to the technical field of energetic materials and analog simulation. The invention aims to solve the problem that the nitrobenzene dangerous real object is extremely dangerous when being directly used as a reference for security check instrument identification, and provides a full-simulation simulant which has the same appearance, color, physical state, density, chemical element and the like as nitrobenzene. The two formulae are as follows: Formula 1: the simulant is prepared from lactic acid, phthalimide and 2,4-toluene diisocyanate in a mass ratio of 0.1927:0.2480:0.5593; and Formula 2: the simulant is prepared from dimethyl malonate, (p-)quinone and 2,4-toluene diisocyanate in a mass ratio of 0.2294:0.0645:0.7061. The nitrobenzene full-simulation explosive simulant can be used instead of nitrobenzene explosives for correction of the security check instrument and other instruments, thereby avoiding potential safety hazard.

Description

technical field [0001] The invention relates to a nitrobenzene fully simulated explosive simulant, and belongs to the technical field of energetic materials and simulation. Background technique [0002] With the escalation of terrorism, the anti-terrorist forces are constantly strengthening, and the contest between terrorism and anti-terrorism will continue for some time. Airports, stations, wharves, and places with dense crowds and important places have always been the targets of terrorist attacks. Therefore, various countries have strengthened security checks on luggage and people's belongings on various routes. Before the security detector identifies whether the substance is an explosive hazardous product, it needs to have a corresponding reference. Usually, the physical object of explosive dangerous goods should not be directly used as a reference, mainly because of the unsafety of explosive dangerous goods and people's fear of explosives. Especially in airports, stat...
