TH8162B - "To stabilize concentrated hydrogen peroxide solution" - Google Patents

Abstract

Hydrogen peroxide concentrated solutions tend to decompose in long time storage therefore losing efficiency For various reasons too, exposure to foreign transition metals It stabilizes the oxygen compound by exposure to the available quantities. Stabilizing effect of compounds with general formula (chemical formula) where X is the formula methylene phosphonic acid group -CH2-(-PO3H2), or its salt, R is tetramethylene diradical, optional. alkyl-substituted by making the ring cyclo-aliphatic complete. and to create two NX2 groups in a significantly definite structure, and Y is a hydrogen or lower alkyl group. Ideally, such a solution contains one type of co-stabilizer or more than can This includes stannates, phosphates, hydroxybenzoic citric acid and nitrates. This will allow the solution to be diluted even if it is tap water.

Claims (1)

1. The process of stabilizing a strong acidic aqueous hydrogen peroxide solution by mixing the peroxide compound with a highly effective stabilizer. The characteristic sterilizers have the following formulas (chemical formula), where X represents the methylene phosphonic acid group with the formula -CH2- (PO3H2) or the acid salt, R. Tetramethylene diracdict That may choose to have Alkyl-substrate can be Which makes the ring The complete cyclo-aliphatic and for that reason results in the formation of two NX2 clusters in a certain structure and Y instead of hydrogen or lower alkyl groups. 2. The process according to claim 1, characterized by this stabilizer, is cyclohexane-1,2-diaminotetramethylenphosphonic acid. 3. The process of claim 1 or 2 is characterized by adding a stabilizer to a solution containing Acidity in water Which contains hydrogen peroxide In the ratio by weight of the stabilizer to Peroxide compounds It ranges from 1: 140 to 1: 70000. 4. Process in accordance with any of the above claims. A unique feature is the use of stabilizers in conjunction with co-stabilizers. Selected from organic acids with many functional groups Which can be cohort Carboxylic acid and / or sulfuric acid or hydroxyl group Or amino groups 5. Process according to claim 4, characterized by co-stabilizers consisting of aliphatic or aromatic hydroxycarboxylic acids. 6. The process according to claim 5, characterized by co-stabilizers, is citric acid or para-hydroxybenzoic acid. 7. Process for any of the above claims It is unique in that this stabilizer is used in conjunction with Co-stabilizer Selected from phosphate. 8. Process according to any of the above 4 to 7 claims. The unique feature is that cattle-stabilizers are used. With stabilizers In the by weight ratio of The co-stabilizer against the stabilizer reaches approximately 1: 1 9. Process in accordance with any of the above claims. Its characteristic is that a stabilizer is used in combination with nitrates or stannates, or both. 1 0. Making a solution of hydrogen peroxide In strong acidic water stabilize By adding compounds With the following formula In the effective quantity (chemical formula) where X represents the methylene phosphonic acid group with the formula -CH2- (PO3H2) or the acid salts, R instead of tetrame. Thylleine Diradical That may choose to have Alkyl-salstituteed Which makes the ring The complete cyclo-aliphatic and for that reason results in the formation of two NX2 clusters in a definite substance structure and Y instead of hydrogen or lower alkyl group. 1 1. Ingredients as per claim 10 and with additional characteristics As described in this manner in any of the 2 to 9 Claims That was mentioned earlier.
