NON-OXIDIZING PARTICLES Russian patent published in 2018 - IPC C01B15/43 C01C1/24 C01D7/00 C01F5/24 C01F7/02 C25B1/28 

FIELD: chemistry.

SUBSTANCE: invention relates to a process for manufacturing non-oxidizing particles. Method comprises a strong oxidizing agent classified as PG I according to the standard method of study of the United Nations Manual on Tests and Criteria, the fifth revised edition, subsection 34.4.1, and at least one additional ingredient. And the quantity and nature of one or more ingredients, which are not a strong oxidant, in the particles are such that the particles are classified as non-oxidizing according to the standard method of study of the UN Manual on Tests and Criteria, fifth revised edition, subsection 34.4.1, in which a strong oxidant is CaO₂ and wherein said at least one additional ingredient is introduced into CaO₂ particles in the process of their manufacture. In this case, CaO₂ are made by adding hydrogen peroxide (H₂O₂) into the hydrated lime, forming CaO₂ crystals, which are then dried. In addition, said one or more additional ingredients are introduced prior to drying the crystals, and said at least one additional ingredient is magnesite or aluminum hydroxide.

EFFECT: technical result is to obtain particles containing CaO_2, which have the advantage of manufacturing in a simple and economic way.
