Abstract: Organic halides are reduced to a dechlorinated products with a catalyst mixture consisting essentially of a nickel compound, a triarylphosphine and a halide ion, in the presence of reducing means for maintaining nickel in the zero valent state.

Abstract: High purity ethylene is prepared by contacting ethyl acetate with a perfluorosulfonic acid resin catalyst at 150.degree.-250.degree. C.

Abstract: A reinforced, filled thermoplastic polymer composition, having increased strength and ductility, contains a reinforcement promoter having at least two reactive olefinic double bonds and a positive promoter index, based on the double bond resonance and polarity, and the promoter adsorptivity.

Abstract: Alkyl amides have been synthesized from cyclic anhydrides, carboxyl acids and their esters by contacting them with an amine carbamic acid salt.

Abstract: Water-borne thermoplastic polyhydroxyether resins are prepared by grafting carboxyl-containing vinyl monomers onto phenoxy resins with a free radical initiator and then converting the graft copolymer to an ionomer suitable for use as protective coatings for metals.

Abstract: Acetic acid has been prepared by a fermentation process using Clostridium thermoaceticum in a varied form obtained by repeated fermentations under anaerobic conditions and low redox potentials at successively more acidic pH's than the original organism.

Abstract: A zinc-rich coating for use on metallic substrates contains particulate zinc, thermoplastic polyhydroxyether and zinc phosphosilicate.

Abstract: Water-borne thermoplastic polyhydroxyether resins are prepared by grafting carboxyl-containing vinyl monomers onto phenoxy resins with a free radical initiator and then converting the graft copolymer to an ionomer suitable for use as coatings or adhesives.

Abstract: Acrylic latex sealants are rendered water-resistant and have improved wet adhesion to a variety of substrates by incorporating hydrophobic resins and an aminosilane hydrolyzate therein.

Abstract: A novel catalyst comprising the elements Mo, V and Nb is provided for oxidizing alpha-beta unsaturated aliphatic aldehydes in the vapor phase with molecular oxygen to produce the corresponding alpha-beta unsaturated carboxylic acid.

Abstract: A novel catalyst comprising the elements Mo, V and Ti, and an oxidation process, is provided for oxidizing alpha beta unsaturated aliphatic aldehydes in the vapor phase with molecular oxygen to produce the corresponding alpha-beta unsaturated carboxylic acid.

Abstract: Substituted olefins are prepared by the reaction of an organic halide with an olefin in the presence of a catalyst derived from zinc, a triarylphosphine and a nickel salt.

Abstract: Olefins can be hydrated to the corresponding alcohols with a hydration catalyst comprising a calcined support consisting of diatomaceous earth, bentonite, silica, cornmeal and cellulose which has been calcined and then impregnated with phosphoric acid.

Abstract: Aliphatic aldehydes are prepared from carboxylic acid esters of primary alcohols by contacting the latter with a wide variety of oxidized elements selected from V, Sb, Mo, and W as well as oxidized element from groups I, III-B, IV, VII-A, and VIII of the periodic system of elements.

Abstract: Injection molding of liquid epoxy resins is facilitated by adding an organic acid plus a siliceous filler to the curable epoxy resin system which thickens and thereby precludes leaking of resin from the mold.

Abstract: Calcined dolomite stabilizes aqueous solutions of viscosifiers, such as polysaccharides, exposed to temperatures as high as 200.degree. F. (93.degree. C.) for prolonged periods.

Abstract: There are provided orthopedic casts, splints, and the like, for use on a portion of a human or animal body, which are produced from a crosslinked copolymer of a lactone monomer and a polyfunctional acrylate monomer. The crosslinked copolymer, in the form of a sheet, web, bandage, etc., and, optionally, a supportive substrate, is heated above the softening point of the copolymer, manipulated to conform to the body portion, and cooled to a rigid state.In one embodiment, there is provided a bandage material, convertible to a rigid, porous, light-weight orthopedic cast, which comprises a substrate in the form of a netting, having on the surface of its strands a coating of the aforementioned crosslinked copolymer. The bandage material is heated to a temperature at which the crosslinked copolymer is soft and self-adherent and is then wrapped around the body portion in a series of overlying layers so as to conform to the contours of the body portion.

Abstract: Benzylic methylene groups are oxidized electrolytically to ketones using a combination of a biphasic aqueous-organic solvent system, a phase transfer catalyst, and a manganese compound in a divided cell.

Abstract: A novel catalyst comprising the elements Mo, V and Ta is provided for oxidizing alpha-beta unsaturated aliphatic aldehydes in the vapor phase with molecular oxygen to produce the corresponding alpha-beta unsaturated carboxylic acid.

Abstract: Single-package zinc-rich coating compositions are provided by blending zinc, a partially-hydrolyzed organic silicate and an aminosilane.
