Patent ID: 7563758

Claim:
A process for producing peroxycarboxylic acid from carboxylic acid ester substrates comprising a) providing a set of peracid reaction components, said components comprising: 1) a carboxylic acid ester substrate selected from the group consisting of: i) esters having the structure wherein R 1 ═C1 to C10 straight chain or branched chain alkyl optionally substituted with an hydroxyl or a C1 to C4 alkoxy group and R 2 ═C1 to C10 straight chain or branched chain alkyl group, (CH 2 CH 2 —O) n H or (CH 2 CH(CH 3 )—O) n H and n=1 to 10; and ii) glycerides having the structure wherein R 1 ═C1 to C10 straight chain or branched chain alkyl optionally substituted with an hydroxyl or a C1 to C4 alkoxy group and R 3 and R 4 are individually H or R 1 C(O); and 2) a source of peroxygen; and 3) at least one Lactobacillus sp. derived-catalyst having a perhydrolysis activity; and b) combining said reaction components under suitable aqueous reaction conditions, wherein said conditions comprise a pH range of about 2 to about 9, whereby a peroxycarboxylic acid is produced at a concentration of at least 500 ppb within about 5 minutes to about 2 hours of combining the reaction components.
