  • Production of peracids using an enzyme having perhydrolysis activity
    Patent number: 8298808
    Abstract: A process is provided for producing peroxycarboxylic acids from carboxylic acid esters. More specifically, carboxylic acid esters are reacted with an inorganic peroxide, such as hydrogen peroxide, in the presence of an enzyme catalyst having perhydrolysis activity. The present perhydrolase catalysts are classified as members of the carbohydrate esterase family 7 (CE-7) based on the conserved structural features. Further, disinfectant formulations comprising the peracids produced by the processes described herein are provided.
    Type: Grant
    Filed: July 2, 2009
    Date of Patent: October 30, 2012
    Assignee: E.I. du Pont de Nemours and Company
    Inventors: Robert DiCosimo, John Edward Gavagan, Mark Scott Payne, Frederick B. Cooling
