Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with specific examples.

[0027] First of all, determine the experimental process of extracting RDX in the cloud explosion agent, including rough grinding, leaching, suction filtration and rotary evaporation, washing, and drying. Examples are as follows:

[0028] Weigh 2g of cloud explosive and place it in a conical flask, measure the quantitative mixed solvent (petroleum ether: acetone=2:8, volume ratio) with a pipette, place the conical flask in a constant temperature water bath of an ultrasonic cleaning machine for ultrasonication, After suction filtration, the filtrate was evaporated to dryness to obtain RDX crystals. After the RDX crystals were washed with a sufficient amount of acetone to remove impurities, suction filtration was collected and the filtrate was evaporated to dryness to obtain purified RDX crystals, which were dried in an oven at 60°C for 5 hours. The recovery rate of RDX...

Abstract

The invention discloses a method for extracting hexogen from a solid fuel air explosive, relating to the technical field of energetic materials. The method comprises the following steps: determining an extraction experiment process for hexogen in the solid fuel air explosive, wherein the process is an ultrasonic leaching crystallization method; selecting the ultrasonic power, the leaching time, the ultrasonic temperature, the material-liquid ratio and the leaching times as experimental factors as well as the extraction rate as an evolution index by virtue of an orthogonal experimental method; selecting a five-factor and five-level orthogonal table according to the value of each factor so as to determine an experiment combination, and carrying out an extraction experiment; analyzing the data of the extraction experiment by virtue of a comprehensive balancing method, and selecting an optimal factor combination process; and carrying out repeated experiment validation by virtue of an optimal factor combination, and determining an optimal process. The method has the characteristics that the elapsed time is short, an operation method is simple and feasible, and the extraction rate is high.

Description

technical field [0001] The invention belongs to the technical field of energetic materials, and in particular relates to a method for extracting RDX from solid cloud blasting agent. Background technique [0002] RDX, also known as cyclone explosive, is a commonly used high explosive and has been widely used in many energetic materials. In the national defense industry, it is used for explosives such as ladder black aluminum, and for civilian production of detonators, detonating cords, and the production of detonating glue. Its chemical properties are stable and powerful, and it is an explosive with excellent comprehensive performance. [0003] The RDX in the solid cloud blasting agent is coated with paraffin, hydroxyl-terminated polybutadiene (HTPB), etc., so it is not easy to be directly dissolved by organic solvents, which increases the difficulty of extraction. In the information that has been found, the recovery of RDX in solid energetic materials by organic solvent pr...
