First Claim
Patent Images
1. A method for forming peroxyformic acid comprising:
- contacting a first reagent that comprises an ester of a polyhydric alcohol and formic acid, and a second reagent that comprises hydrogen peroxide or a substance that generates hydrogen peroxide to form peroxyformic acid,wherein the formed peroxyformic acid comprises at least about 1 ppm peroxyformic acid within about 1 minute, andwherein the pH of said formed peroxyformic acid becomes about 8 or lower within about 1 minute after the contact between said first reagent and said second reagent andwherein the method for forming peroxyformic acid does not include an enzyme catalyst.

16. A method for forming peroxyformic acid comprising:
-
contacting a first reagent that comprises an ester of a polyhydric alcohol and formic acid, and a second reagent that comprises hydrogen peroxide or that comprises a substance that generates hydrogen peroxide when in contact with a liquid, to form a liquid that comprises from about 0.1 ppm to about 100,000 ppm of peroxyformic acid and wherein the pH of said formed liquid becomes about 8 or lower within about 1 minute after the contact between said first reagent and said second reagent; and wherein the first reagent and the second reagent are contacted to form a solution that comprises at least about 1 ppm peroxyformic acid within about 1 minute of the contact time; and wherein the method for forming peroxyformic acid does not include an enzyme catalyst. - View Dependent Claims (17, 18, 19, 20)
