Abstract

The invention relates to the production of artificial carbon-based materials, in particular to the production and purification of ultra-dispersed synthetic diamonds and can be used for extracting diamond-containing materials from the products of a detonation synthesis. The inventive method involves the detonation transformation of explosive material having a negative oxygen balance in the closed space of a blasting chamber in a nonoxidizing atmosphere, the evacuation of explosion products and the heat chemical purification thereof by a mineral acid followed by washing of impurities therefrom. The condensed detonation products are additionally exposed to the action of a shock wave, the chemical purification is carried out with a nitrogen acid aqueous solution in three stages: in the first stage, in periodic mode at a temperature ranging from 20 to 60 °C during the time of 0.5 to 5 hours; in the second stage, in continuous mode and in five temperature zones at a temperature ranging from 110 to 300 °C during the time of 20 to 120 minutes; and in the third stage, in periodic mode at a temperature ranging from 20 to 80 °C during the time of 0.5 to 5 hours with the additional blowing of a reaction mass by an oxygen-containing gas mixture. The additional action of the shock wave on the condensed products is carried out repeatedly from 1 to 50 times at intervals ranging from 5 to 20 minutes, the pressure of a front shock being specified within the range of 0.4 to 15.0 MPa.

At temperatures above 300 ° C, there is an increase in the safety of equipment. The fifth temperature zone uses cooling of the reactive mass and preliminary separation of the various gas and suspension products. Cooling may occur due to 13 Heat exchange with water or cooling water, or with a reactive mixture that is used to empty the machine. Depending on the particular conditions of the organization of the process in this area, the temperature of the suspension should be maintained at an interval of 30-150 ° C. A temperature lower than 30 ° C is required for the organization of energy-efficient refrigeration, which is economically unsuitable. A temperature limit of more than 150 ° C is undesirable, t.κ. In this case, the conditions for the expansion of the reactive mass are deteriorated due to the intense pressure of the valve and the associated armament.
