Abstract
The invention describes to compositions useful to stabilize peracetic acid, acetic acid and hydrogen peroxide compositions with polymeric phosphonic acid resins or with 1-hydroxyethylidene-1,1,-diphosphonic acid associated with the interior surface of a container to stabilize the peracetic acid, acetic and hydrogen peroxide compositions.
Claims22
A method to stabilize a peracetic acid and hydrogen peroxide solution comprising the step:
- contacting a peracetic acid and hydrogen peroxide solution with a polymeric resin functionalized with phosphonic acid to provide a treated peracetic acid and hydrogen peroxide solution, wherein the polymeric resin functionalized with the phosphonic acid is a polymerized resin of vinylidene diphosphonic acid or a copolymer of vinylidene diphosphonic acid.
A packaged solution comprising:
- a peracetic acid and hydrogen peroxide solution treated with a polymeric resin functionalized with phosphonic acid to provide a treated peracetic acid and hydrogen peroxide solution, wherein the polymeric resin functionalized with the phosphonic acid is vinylidene diphosphonic acid or a copolymer of vinylidene diphosphonic acid;
- and
- a container, wherein the treated peracetic acetic acid and hydrogen peroxide solution is contained.
A packaged solution comprising:
- a peracetic acid and hydrogen peroxide solution treated with a polymeric resin functionalized with phosphonic acid to provide a treated peracetic acid and hydrogen peroxide solution;
- and
- a container, wherein the treated peracetic acetic acid and hydrogen peroxide solution is contained, wherein the treated peracetic acid and hydrogen peroxide solution is stable at ambient conditions for at least 18 months and retains at least a 60% concentration of the original concentration of the peracetic acid at least 180 days, 365 days or 545 days.
