N-acyl azolinones as peroxygen bleach activators

Abstract

Abstract N-ACYL AZOLINONE COMPOUNDS HAVING A FORMULA SELECTED FROM 1-X,2-(O=),3-Y,4,5-(-A-)-4-IMIDAZOLINE, 1-X,2-(O=),3-Y, 4-R2,5-R1-4-IMIDAZOLINE, 2-(O=),3-Z,4,5-(-A-)-4- THIAZOLINE, AND 2-(O=),3-Z,4,5-(-A-)-4-OXAZOLINE WHEREIN: A REPRESENTS A COMPLETED BENZENE OR NAPHTHALENE RING SYSTEM WHICH MAY CARRY A SUBSTITUENT SELECTED FROM ALKYL, ALKOXY, HALO, NITRO, CYANO AND ACETAMIDO; X REPRESENTS HYDROGEN, ACETYL, PROPIONYL, BENZOYL, CINNAMOYL, PHENYLSULFONYL OR 2-FUROYL; Y REPRESENTS ACETYL, PROPIONYL, BENZOYL, CINNAMOYL, PHENYLSULFONYL OR 2-FUROYL; Z MAY BE THE SAME AS Y OR A RADICAL SELECTED FROM 2-(O=),3-((-)CO-CO-),4,5-(-A-)-4-THIAZOLINE, AND 2-(O=),3-((-)CO-CO-),4,5-(-A-)-4-OXAZOLINE RADICALS; AND R1 AND R2 INDIVIDUALLY REPRESENT HYDROGEN, ALKYL OR PHENYL; ARE EFFECTIVE AS BLEACH ACTIVATORS IN BLEACHING COMPOSITIONS COMPRISING HYDROGEN PEROXIDE OR A HYDROGEN PEROXIDE-RELEASING COMPOUND. THE ACTIVATED BLEACHING COMPOSITIONS ARE USEFUL FOR VARIOUS BLELACH APPLICATIONS, INCLUDING FABRICS, PARTICULARLY WHEN INCORPORATED IN DETERGENT LAUNDERING COMPOSITIONS IN WHICH THEY SHOW GOOD STORAGE STABILITY AND HIGH EFFECTIVENESS AT LOW (50-70*C.) TEMPERATURE.
