METHOD FOR MARKING EXPLOSIVE Russian patent published in 2008 - IPC C06B23/00 G01N33/22 

FIELD: explosives.

SUBSTANCE: proposed method for marking an explosive consists in adding a marking composition into the explosive, not less than 200 g per tonne of the explosive. Said marking composition contains identifiers, the number of which is equal to the number of technical indexes, and is made of synthetic organic or inorganic compounds of a class of colouring agents and/or low-molecular polymers from the international CAS registry of chemicals having a molecular weight not less than 1000 g/mol. Furthermore, it is proposed to use identifiers that are oil- and fat-soluble, resistant to chemicals in media at all PH ranges, resistant to free radicals damage, chemically inert to the components of the explosive, chemically inert to the products of explosion and do not possess any properties of surface-active reagents or any toxic properties. When used simultaneously, the compounds of the colouring agent class and those of the low molecular polymers class must not enter into chemical reaction between them.

EFFECT: ensuring the reliability of the process of marking explosives by various technical indexes.
