Abstract
Methods for stabilizing one or more peroxide compounds in solution comprising adding to the solution an effective amount of at least one compound selected from the group comprising (i) cyclic carbonates; (ii) poly-phosphonic acid chelating agents and salts thereof, and alkaline pH adjusting agents with a pKb value of up to 3.0, wherein the w/w ratio of the poly-phosphonic acid chelating agent or salt thereof to alkali or alkaline earth metal hydroxide is from about 1:1 to about 50:1; and (iii) mixtures thereof. Also disclosed are solutions comprising the above compounds, uses of the above compounds to stabilize peroxide compounds in solutions, and compounds recited above for use as novel stabilizers.
Claims16
A method of stabilizing a peroxide compound in a solution comprising adding to the solution an effective amount of poly-phosphonic acid chelating agents or salts thereof, and alkaline pH adjusting agents with a pKb value of up to 3.0, wherein the w/w ratio of the poly-phosphonic acid chelating agent or salt thereof to the alkaline pH adjusting agent is from about 1:1 to about 100:1, and wherein the pH of the solution is from about 0.1 to 2;
- wherein combinations of the poly-phosphonic acid chelating agents or salts thereof and the alkaline pH adjusting agents with a pkb value of up to 3.0 are peroxide stabilizing agents, wherein the solution optionally comprises cyclic carbonates as peroxide stabilizing agents, and wherein the solution is free of additional peroxide stabilizing agents.
