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 methanol nitrate simulants and related information have been retrieved

Embodiment
[0025] Put a 500ml clean Erlenmeyer flask into a magnet for stirring, first add 45.04g of precisely measured formamide, start stirring, adjust the stirring speed to 600r / min, add 46.03g of formic acid, continue stirring and mixing for 10min after the addition, and then maintain 600r / min Add 63.01g of accurately metered nitric acid to the mixture under the stirring condition of / min, and continue to stir and mix for 30 minutes after the addition is completed, so that the liquid substance is completely mixed, and then the methanol nitrate liquid explosive simulant can be obtained. The determined element percentage content is: C 15.46%, H 3.88%, O6 2.56%, N 18.10%, the error is within ± 2%, and its atomic number is calculated to be equal to methanol nitrate, compared with real methanol nitrate , the atomic number is equal, the color appearance is the same, and the element percentage is within the error range, which is consistent with methanol nitrate.
[0026] The element percent...

The invention relates to carbinol nitrate full-simulation explosive mimics and belongs to the technical field of energetic materials and simulation. The invention provides the full-simulation mimics which are used for solving the problem that a carbinol nitrate dangerous material object is extremely dangerous when being directly used as a reference object to be identified by a security check instrument, and have the same appearance, color, matter state, density, chemical elementary composition and the like. The carbinol nitrate full-simulation explosive mimics are prepared by a method that formamide, formic acid and nitric acid are weighed according to the proportional relation of the molar ratio of 1:1:1, formic acid is added into the formamide at the mixing speed of 600 rounds / minute, and is continuously mixed for 10 minutes after being completely added, nitric acid is added into the mixture under the mixing condition of 600 rounds / minute, and is continuously mixed for 30 minutes after being completely added, and liquid substances are completely mixed, so the carbinol nitrate full-simulation explosive mimics are obtained. The carbinol nitrate full-simulation explosive mimics can substitute for a carbinol nitrate full-simulation explosive to be used for correction of the security check instrument and other instruments, so potential safety hazards are avoided.
Description
technical field [0001] The invention relates to a fully simulated explosive simulant of methanol nitrate, 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 airport...
