PENTAERYTHRITOL TETRANITRATE MODIFIED WITH CARBON NANOTUBES AND METHOD FOR ITS PREPARATION Russian patent published in 2022 - IPC C06B49/00 B82B3/00 

Abstract RU 2777333 C1

FIELD: chemical industry.

SUBSTANCE: invention relates to explosives that can be used for the manufacture of detonating cords, igniter caps and initiation devices for the mining industry. In the method for obtaining pentaerythritol tetranitrate modified with carbon nanotubes, modification is carried out during recrystallization by introducing an aqueous suspension of carbon nanotubes into a solution of pentaerythritol tetranitrate in acetone heated to a temperature of 40 to 60°C into a reaction mixture at a rate of 0.005% to 0.1% by weight of pentaerythritol tetranitrate. The total volume of the injected aqueous suspension is at least two volumes of pentaerythritol tetranitrate solution in acetone.

EFFECT: specific volumetric electrical resistance of pentaerythritol tetranitrate is decreased to values from 1.0 Ohm∙m to 5.0∙104 Ohm∙m.
