INORGANIC SALT-HYDROGEN PEROXIDE COMPLEXES AND SYNTHESIS THEREOF Russian patent published in 2002 - IPC

FIELD: inorganic synthesis. SUBSTANCE: inorganic salt, in particular sodium, potassium, calcium, or magnesium phosphate or condensed phosphate, or sodium silicate, is mixed with water to give a soft paste, to which 12-89% aqueous solution of hydrogen peroxide is added. Mixture is aged for 5 to 30 min at pressure 0.2 Tor and dried "in vacuo" or in drying box. Resulting complexes have following empirical formulas: Na₄P₂O₇•nH₂O₂ or K₃PO₄•nH₂O₂, in which n≥2 preferably n= 3, Na₂SiO₃•nH₂O₂, in which n≥1 Ca₂P₂O₇•nH₂O₂; Mg₂P₂O₇•nH₂O₂; Na₂SO₄•nH₂O₂; K₂SO₄•nH₂O₂; and Na₂Si₃O₇•nH₂O₂. Essentially waterless complexes can be used as disinfectants and sterilizers for medical tools and equipment. EFFECT: improved ability of disinfecting and sterilizing both metallic and nonmetallic parts and surfaces at room and elevated temperatures. 23 cl, 25 dwg, 53 tbl, 48 ex
