Electrolytic Synthesis Of Peracetic Acid
View pageUS Patent:
6387238, May 14, 2002
Filed:
Aug 2, 2000
Appl. No.:
09/630934
Inventors:
Tom L. Merk - Chesterland OH
Paul S. Malchesky - Painesville Township OH
Paul S. Malchesky - Painesville Township OH
Assignee:
Steris Inc. - Temecula CA
International Classification:
C25B 300
US Classification:
205439, 205440, 2042751, 204252
Abstract:
An electrolysis unit ( ) has an anode ( ) and a gas diffusion cathode ( ). Air is fed to the cathode ( ) to generate peroxide species, such as hydrogen peroxide, peroxide ions, or peroxide radicals by electrolysis of oxygenated water. A peracetic acid precursor, such as acetyl salicylic acid, reacts with the peroxide to form peracetic acid. An ion selective barrier ( ) optionally separates the unit into two chambers, an anodic chamber ( ) and a cathodic chamber ( ). By selecting either a proton permeable membrane or an anion exchange membrane for the barrier, the peracetic acid may be formed in either an alkaline electrolyte in the cathodic chamber or in an acid electrolyte in the anode chamber, respectively.
Electrolytic Synthesis Of Peracetic Acid And Other Oxidants

61715514, Jan 9, 2001
Filed:
Aug 7, 1998
Appl. No.:
9/130814
Inventors:
Paul S. Malchesky - Painesville Township OH
Tom L. Merk - Chesterland OH
Tom L. Merk - Chesterland OH
Assignee:
Steris Corporation - Mentor OH
International Classification:
A61L 900
US Classification:
422 29
Abstract:
An electrolysis unit (10) has an ion selective barrier (20) for separating an anodic chamber (12) from a cathodic chamber (14). An electrolyte within the unit includes a precursor, such as potassium acetate, or acetic acid. A positive potential is applied to an anode (16) within the anodic chamber, resulting in the generation of a variety of shorter and longer lived oxidizing species, such as peracetic acid, hydrogen peroxide, and ozone. In one preferred embodiment, a solution containing the oxidizing species is transported to a site where articles, such as medical instruments, are to be decontaminated. The oxidizing species are generated as needed, avoiding the need to store hazardous decontaminants.
