    Abstract: There is provided a process for enhancing the activity of a phenol oxidizing enzyme, comprising adding to the enzyme, as an enhancer for the activity of the enzyme, one or more compounds having the formula: wherein: A is an optionally substituted electron-withdrawing group, chosen from the group consisting of nitrile, carboxyl, and esters and salts thereof, amides, aldehydes, ketones, sulfoxides, sulfones, or sulphonates, and B is an optionally substituted electron-donating group, chosen from the group consisting of the oxide anion, sulfide anion, oxides, amines, imines, hydroxides, sulfides, ethers, carboxylic acids, and halogen substituents, and R1-R5 may each independently represent hydrogen, hydroxy, halogen, nitroso, formyl, carboxyl, and esters and salts thereof, carbamoyl, sulfo, and esters and salts hereof, sulfamoyl, nitro, amino, phenyl, C1-C20 alkyl, C1-C8 alkoxy, carbonyl-C1-C6-alkoxy, aryl-C1-C6-alkyl, and R2 and R5 together may form an alkylene group or an alkenylene group.

  • Patent number: 6270690
    Abstract: The invention relates to storage-stable bleach activator granules consisting essentially of a bleach activator and an acid-modified phyllosilicate, prepared by mixing a dry bleach activator with a dry, acid-modified phyllosilicate, compressing this mixture to give relatively large agglomerates and comminuting these agglomerates to the desired particle size.

  • Patent number: 6241779
    Abstract: The invention provides a novel composition and method for removing or reducing levels of recalcitrant constituents from an effluent, such as lignin chromophores, AOX species, such as chlorinated phenols, dioxins, dibenzofurans, biphenyls, and high molecular weight material produced in the pulp and paper bleaching operations which includes using a composition comprised of (a) an amount of a source of an oxidant effective for oxidizing and thereby reducing the levels of such constituents and (b) an oxidatively stable oxidant activator having the structure wherein Y1, Y3 and Y4 each represent a bridging group having zero, one, two or three carbon containing nodes for substitution, and Y2 is a bridging group having at least one carbon containing node for substitution, each said node containing a C(R), C(R1)(R2), or a C(R)2 unit and each R substituent is the same or different from the remaining R substituents; M is a transition metal with oxidation states of I, II, III, IV, V, VI, VII or VIII or

  • Patent number: 6235218
    Abstract: A process is provided for the preparation of a compound having the structure of Formula I The process includes reacting a heterocyclic amine with a monoaldehyde or a dialdehyde in a pH range of from about 8 to 14 and then quaternizing the so-reacted heterocyclic amine with an alkylating agent at a pH of not less than about 2. The use of pH control substantially prevents formation of an undesirable protonated reaction intermediate.

  • Patent number: 6211130
    Abstract: The invention relates to the use of quaternary acetonitrile compounds corresponding to formula (I): in which R1, R2 and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms and the groups R2 and R3 may also be part of a heterocycle including the N atom and, optionally, other hetero atoms and X is a charge-equalizing anion, for activators for detergents, more particularly detergents containing inorganic peroxygen compounds. The activators may be directly added to liquid detergents or may be added to the wash liquor together with the detergents in the form of aqueous preparations. Without the addition of hydrogen peroxide, a distinct color-lightening effect is obtained, even at low washing temperatures.
