Stabilized hydrogen peroxide solutions
Abstract
Abstract ACIDIC STABILIZED HYDROGEN PEROXIDE SOLUTIONS ARE DISCLOSED WHICH CONTAIN FROM ABOUT 10 TO 90% H2O2, A SOLUBLE STANNATE STABILIZER, A SOLUBLE MAGNESIUM SALT SUCH AS EPSOM SALT, AT A CONCENTRATION OF AT LEAST 10 GRAMS PER LITER, AND AN ALKYLIDENE DIPHOSPHONIC ACID OR A SOLUBLE SALT THEREOF AT A CONCENTRATION SUFFICIENT TO PREVENT PRECIPITATION OF THE STANNATE BY THE MAGNESIUM SALT. IN PREFERRED EMBODIMENTS, THE HYDROGEN PEROXIDE SOLUTION WILL ALSO CONTAIN A SOLUBLE PYROPHOSPATE OR FLUOSILICATE. WHEN DILUTED WITH WATER TO PEROXIDE CONCENTRATIONS GENERALLY EMPLOYED IN MOST USE APPLICATIONS, THE DILUTED SOLUTIONS REQUIRE ONLY THE ADDITION OF AN ALKALI TO PROVIDE ALKALINE PEROXIDE SOLUTIONS CONTAINING A MAGNESIUM COMPOUND WHICH IS AN EFFECTIVE STABILIZER FOR THE ALKALINE PEROXIDE SOLUTIONS DURNG USE, E.G. IN BLEACHING APPLICATIONS.
