  • Patent number: 4927559
    Abstract: A bleaching composition is disclosed comprising a peroxygen bleaching compound, capable of yielding hydrogen peroxide in an aqueous media, and one or more bleach precursors wherein the peroxygen bleaching compound and precursor are present in a molar ratio that ranges from 0.1 to 2. It is also important that bleaching occur in an aqueous media held at a pH from 8.5 to 9.4. A combination of sodium perborate and sodium benzoyloxybenzene sulfonate is the preferred bleaching composition.

  • Patent number: 4659826
    Abstract: A method of synthesizing and recovering with high yield and purity salicylamide compounds of the formula: ##STR1## wherein R.sub.1 is a substituent having the formula --COC.sub.n H.sub.2n+1 wherein n is an integer with a value of from 1 through to about 15, R.sub.2 is a substituent selected from the group consisting of --H, --NO.sub.2, --F, --Cl, --Br, --I, --CF.sub.3, --CBr.sub.3, --CCl.sub.3, --CI.sub.3 and R.sub.1 and R.sub.3 is an R.sub.2 substituted heterocyclic compound selected (e.g.) from the group consisting of furan, thiazole, benzothiazole and purine by:(a) reacting a phenyl salicylate ester bearing an R.sub.1 substituent on the benzene ring of the salicylic acid portion thereof with an R.sub.2 substituted aniline or a heterocyclic amine NH.sub.2 -R.sub.3, optionally in the presence of an inert solvent such as a halogenated or unhalogenated aromatic compound or a carbowax solvent, e.g.
