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 ether peroxide simulants and related information have been retrieved

Embodiment
[0025] In a 300ml clean Erlenmeyer flask, put in a magnet for stirring, add 58.08g of acetone accurately measured, put in a magnet for stirring, start stirring, and at a stirring speed of 600r / min, add accurately measured methanol, mixed and stirred for 30 minutes until the solution was completely mixed, and discharged to obtain a liquid ether peroxide simulant. The determined element percentage content is: C 53.72%, H 11.02%, O 35.26%, the error is within ± 2%, and its atomic number is calculated to be equal to that of ether peroxide. Compared with ether peroxide, its atomic number is equal, and its color is The appearance is the same, and the element percentage is within the error range, which is consistent with ether peroxide.
[0026] The element percentage and density of the ether peroxide simulant of each embodiment are compared with the real sample data of ether peroxide as shown in the following table:

The invention relates to a peroxide diethyl ether full-simulating explosive analog, belongs to the technical field of energetic material and analog simulation, and aims to solve the problem that a peroxide diethyl ether dangerous good entity is directly served as the reference substance to be distinguished via a security instrument, which brings high risk. To solve the problem, the invention provides a full-simulating explosive analog which has the same appearance, color, physical state, density, chemical elements composition and the like as the peroxide diethyl ether. A specific preparation method of the peroxide diethyl ether full-simulating explosive analog provided by the invention comprises the steps as follows: weighing acetone and methanol based on the mol ratio of 1: 1; adding the methanol to the acetone at a speed of 20g / min under the stirring speed of 600r / min; then mixing and stirring for 30 minutes until the solution is completely mixed; and finally discharging to obtain the liquid peroxide diethyl ether analog. The peroxide diethyl ether full-simulating explosive analog provided by the invention can be used for replacing peroxide diethyl ether explosive to carry out the correction of the security instrument and the like, thus, the potential security risk can be avoided.
Description
technical field [0001] The invention relates to a fully simulated explosive simulant of ether peroxide, 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,...
