Abstract: A process for preparing improved polymeric binder for use in protective surface coatings comprising heat reacting glycoluril or melamine with a time sufficient to partially coreact or otherwise associate the glycoluril or melamine with the reactive emulsion polymer.
Abstract: There is provided a multi stage process for nonselectively chlorinating a titaniferous ore containing iron to produce TiCl.sub.4. In this process a portion of the ore charge is subjected to conventional fluid bed chlorination to produce TiCl.sub.4 and FeCl.sub.2. A second portion is subdivided and submitted to chlorination in a dilute phase chlorination step using FeCl.sub.3 as the chlorinating agent to produce additional TiCl.sub.4. The FeCl.sub.3 is obtained by partial oxidation of the FeCl.sub.2 obtained in the first stage and/or second stage to yield Fe.sub.2 O.sub.3 and FeCl.sub.3. The product streams of TiCl.sub.4 are then combined for further treatment.
Abstract: A particulate food acidulant is prepared by plating lactic acid onto particulate calcium lactate carrier and then encapsulating said carrier and acid with a molten edible lipid.
Abstract: There is provided a process for the addition of a secondary aliphatic amine to myrcene or an 8-substituted myrcene and isomerization to a dialkyl 1,3-dienamine. The process is liquid phase and employs an excess of the amine relative to myrcene or substituted myrcene. The catalyst is an alkali metal amide anion formed from the amine.

Abstract: The process comprises polymerizing monomers, especially including methacrylic monomer, in the presence of azo catalyst and between 0.0001% and 0.01% of Cobalt (II) dimethylglyoxime pyridine or similar Cobalt (II) complexes to produce a low molecular weight polymer or copolymer.
Abstract: An improved cathodic electrocoating composition comprises an aqueous suspension of synthetic, cation-active, film-forming latex particles characterized by a latex gel content that is not substantially above about 10%.
Abstract: A protective surface coating composition particularly useful for wood coating containing hydroxylated polyester, glycoluril, and emulsion polymer can be heat cured to produce cured films on substrates. The coating is particularly useful as wood coatings.
Abstract: The present invention relates to novel, edible lauric hard butter compositions suitable for the preparation of confectionery coatings, and particularly to a novel emulsifier ester blend found to be beneficial in improving the performance of lauric hard butters in confectionery coatings, towards obtaining unexpectedly high gloss and gloss retention.
Abstract: Emulsion polymers produced by polymerizing ethylenically unsaturated monomers in an aqueous medium can be substantially improved by incorporating into the monomer mixture a minor amount of blend of epoxy resin and glycidyl acrylate. The epoxy modified emulsion polymers are particularly useful as ambient or low temperature thermosetting latices for film-forming coatings.
Abstract: The invention pertains to coating compositions comprising self-curing water-dispersed polymers, epoxy-acrylic copolymers, and preferably including epoxy phosphate polymers. The self-curing water-dispersed polymers produced preferably by step-wise polymerization of ethylenically unsaturated monomers comprising alkylol acrylamide monomer, functional monomers, and other monomers, wherein the alkylol acrylamide monomers are copolymerized in the second stage monomer addition to preferentially locate alkylol acrylamide groups in the surface portion of the latex polymer particles. Melamine resins can be added to improve the cure properties of the coating composition. The coating compositions are advantageously sprayable compositions and are particularly useful for interior coatings for food and beverage containers.
Abstract: A process for treating wood substrate, including textured hardboard having surface irregularities consisting of high ridge areas protruding above the surface, with a low viscosity aqueous coating to produce a coated article having substantially uniform film thickness. A substantially uniform film can be obtained by preheating the substrate (about 250.degree. to 400.degree. F.), flooding the surface with the aqueous coating, partially dewatering and affixing the coating to the surface by coalescence and removing the excess coating. It is necessary to critically control the substrate temperature and time in which the coating remains in contact with the heated substrate before the excess coating is removed using an air knife.
Abstract: There is provided an improved process for chlorinating an iron-containing titaniferous ore, such as ilmenite which comprises dividing the ore charge into 2 parts. The first and major part is chlorinated with chlorine or with a mixture of chlorine and FeCl.sub.3 under fluidized bed conditions to yield principally TiCl.sub.4 and FeCl.sub.2. The FeCl.sub.2 is separated out and utilized as a chlorinating agent for the minor part of the ore in an entrained flow chlorinator to yield more TiCl.sub.4 and metallic iron as principal products. This process avoids the need for disposal of FeCl.sub.2 and retains the advantages of conventional chlorination procedures.
Abstract: An improvement in process for making cupreous catalyst composition, wherein a copper oxide-preponderant grind charge derived from the oxidation of elemental copper and/or an alloy thereof is subject to high energy milling with concomitant crystal lattice distortion until the average particle of the resulting grind is no larger than about 20 microns, comprises establishing a tin concentration between about 400 and about 3000 ppm in said composition prior to or after said high energy milling. The resulting catalyst is useful for producing organohalosilane from alkyl chloride and silicon.

Abstract: The present invention resides broadly in a method for applying water soluble coatings to highly water soluble core particles selected from the group consisting of sugar, salt, yeast, and solid acidulants, comprising the steps of selecting core particles of fine particle size such that a preponderance of the particles pass through a 16 mesh screen, U.S.

Abstract: Improved gloss retention of a cured film deposited by cathodic electrocoating is obtained when the principal binder is an aqueous suspension of synthetic, cation-active, film-forming, emulsion-polymerized latex particles, which latex is characterized by Tg of at least about 20.degree. and desirably even higher.
Abstract: A grind charge of cupreous particulates containing a major proportion of cuprous and cupric oxides and a minor proportion of elemental copper, said charge having average particle size above 15 microns, is subjected to high energy comminution with concomitant crystal lattice distortion until the average particle size of said particulates is no larger than 15 microns. The resulting catalyst, of fairly high specific surface area, can be used for alkyl or aryl halosilane production.

Abstract: A process for dispersion strengthing of atomized alloy particles by internal oxidation is substantially improved by providing atomized particles substantially free of oxide surface film to enhance the efficiency of the internal oxidation step. The atomized alloy particles can be produced by dry collection to prevent oxide film formation, or alternatively, the oxide surface film can be removed by mechanical action removal or by chemical leaching.
