  • Patent number: 4614757
    Abstract: A chelate of zinc with 4,4'-dihydroxydiphenyl sulfone is obtained in a solvent-free system for use as a color developer in carbonless copy paper systems. The 4,4'-dihydroxydiphenyl sulfone is solubilized in an aqueous medium by reacting with a water-soluble amine. A mineral matrix is then added followed by the addition of a zinc halide, preferably zinc bromide, to cause the chelate of zinc with 4,4'-dihydroxydiphenyl sulfone onto and within the structure of the mineral matrix. After removal of any excess zinc cations, and addition of any desired fillers, a binder is added and the composition coated onto the substrate.

  • Patent number: 4335055
    Abstract: Compounds of the formula I ##STR1## in which Z, Z.sub.1, R, m and p are as defined in patent claim 1, can be obtained in a simple and economical manner by a novel process wherein a halide of the formula II ##STR2## is reacted with a substituted or unsubstituted vinylbenzene or vinylnaphthalene derivative in the presence of a base and of certain palladium catalysts, such as palladium acetate. The compounds (I) or functional derivatives preparable therefrom are useful, for example, for the preparation of known dyes or fluorescent brighteners, or can be used directly as fluorescent brighteners or as scintillators.

  • Patent number: 4326047
    Abstract: Polyether hydroxyl-containing compounds are prepared by reacting a monoepoxy-containing compound such as propylene oxide with a compound containing one or more OH and/or SH groups such as a low molecular weight adduct of glycerine and propylene oxide in the presence of a solid calcium naphthenate catalyst. The solid form of the catalyst is more efficient than the liquid form.

  • Patent number: 4320215
    Abstract: A method of preventing scale formation and adhesion onto the surfaces of a polymerization vessel and auxilliary equipment used in polymerization of vinyl chloride monomer, wherein the surfaces are coated prior to polymerization with a coating agent having the concurrent properties of (a) one or more functional groups having the ability to chelate, (b) one or more functional groups having the ability to inhibit action of free radicals, and (c) substantial insolubility to vinyl chloride monomer and insoluble to water. The concurrent presences of these functional characteristics syngergistically act to prevent scale adhesion onto the surfaces after substantial numbers of repeated polymerization charges.

  • Patent number: 4310702
    Abstract: Sulfuryl chloride is reacted in the liquid phase with an organic reactant which is a ketone or aromatic alcohol unsubstituted on both ortho carbons in the presence of a moderator selected from the group consisting of aliphatic alcohols of 1-3 carbons and aliphatic ethers of 2-6 carbons, with sufficient moderator being present to selectively produce a product substantially free of compounds with more than one chlorine atom per carbonyl or aromatic hydroxy. The products, such as monochloroacetone, monochlorocyclohexanone, monochlorophenol and 2,2-bis(3-chloro-4-hydroxyphenyl)propane, are useful as chemical intermediates and as monomers for flame retardant polymers.
