Problems solved by technology

Therefore, when hydrogen peroxide is produced, transported and applied, it is generally necessary to add a small amount of stabilizer to promote the stability of hydrogen peroxide; when the concentration of hydrogen peroxide is low (mass concentration is less than 30%), water glass, ethylenediaminetetra Traditional substances such as acetic acid or polyacrylic acid are used as stabilizers, but the above stabilizers are not suitable for use under strong alkaline conditions, nor for the storage and application of hydrogen peroxide with a high concentration

Abstract

The invention discloses a hydrogen peroxide stabilizer, the mass percentage of which is composed of: 15-30% of organic phosphonic acid; 10-15% of magnesium salt; 55-75% of distilled water; the sum of each component is 100%. Magnesium salts include magnesium chloride, magnesium sulfate, magnesium acetate, magnesium nitrate or magnesium perchlorate; the organic phosphonic acid has the structure of general formula (1), wherein R represents a substituent, which is an alkyl group or a heteroatom-substituted alkyl group ; n represents the number of phosphonic acid groups connected to the substituent R, and n=2-5. Under the synergistic action of organic phosphonic acid and magnesium salt, the stabilizer of the invention can effectively realize the stabilization of hydrogen peroxide under strong alkaline conditions.

Description

technical field [0001] The invention relates to a chemical stabilizer, in particular to a hydrogen peroxide stabilizer and a preparation method thereof. The hydrogen peroxide stabilizer can ensure that high-concentration hydrogen peroxide has a lower decomposition rate under strong alkaline conditions. Background technique [0002] Hydrogen peroxide, also known as hydrogen peroxide, is an important inorganic chemical product, widely used in fields such as textile, paper making, chemical industry, light industry, medicine, electronics, food, environmental protection and military industry. Pure hydrogen peroxide or its aqueous solution can decompose slowly at normal temperature. When the temperature rises or ultraviolet rays are irradiated, the decomposition speed is accelerated. When it encounters dust, heavy metal ions or alkaline substances, it will decompose violently, so it will not The cost of materials has been greatly improved, and safety accidents are prone to occur....
