Abstract: Hydroxyaromatic compounds are amido-alkylated or cyano-alkylated to form the corresponding compounds by:(a) heating said compounds with an alkylating agent in the presence of water and a catalyst, e.g., benzyltrimethylammonium chloride;(b) adding an alkaline agent, e.g., NaOH, to the heated mixture of (a); and(c) continuing to heat the resulting mixture until the corresponding amido- or cyano-alkylated compound is formed.Fully or partially amido-alkylated compositions are useful in the preparation of copolymers with epoxy resins.

Abstract: An isomeric mixture of C- and O-allylated aromatic compounds is prepared by contacting an allyl halide, a hydroxyaromatic reactant, an alkaline agent, water and a quaternary salt catalyst. This mixture may be thermally isomerized to obtain the C-allylated compounds in high yield.

Abstract: Selectively produce methane under Fischer-Tropsch conditions using a catalyst consisting essentially of ruthenium supported on an oxide of tantalum, niobium, vanadium or mixtures thereof, the support preparation including calcination at a temperature such that essentially no crystalline metal oxide is detectable by X-ray diffraction prior to deposition of the catalytic metal.

Abstract: Partially neutralize a strong-acid cation-exchange resin in acid form using an N-(2-mercaptoalkyl)amide in the presence of water.

Abstract: Prepare p-isopropenyl phenol and other alkenyl aromatic compounds by contacting a dihydroxydiphenyl alkane or a related substituted diaromatic alkane with an alkaline catalyst and at least one gas under supercritical conditions such that p-isopropenyl phenol or the corresponding related alkenyl aromatic compound is produced.

Abstract: Prepare alkylene glycols by hydrolyzing alkylene carbonates under specific conditions, and a reactor specially designed therefor.

Abstract: Prepare 4-amino-1,3-dicyano-2-methyl-1,3-pentadiene and related substituted aminodienes by contacting .beta.-aminocrotononitrile and related substituted aminoalkenes with a base acceptor in a solvent under mild conditions.

Abstract: An improved process for the preparation of metal oxide fibers, which process employs the acrylate salt of the metal.

Abstract: A novel imidazolinium salt is prepared by (1) reacting N-aminoalkyl-imidazoline, N-hydroxyalkyl-imidazoline, or N-substituted-imidazoline with an .alpha.,.beta.-unsaturated ester of a carboxylic acid, (2) reacting the resulting ester imidazoline with a primary or secondary amine and (3) quaternizing the resulting amido imidazoline product by reacting it with an alkylating agent. This imidazolinium salt is useful as a fabric softening agent.

Abstract: Prepare hydroxyaromatic ethers by contacting an oxidizing agent with an acylaromatic ether in the presence of an acid catalyst.

Abstract: Photocurable compositions containing a polyethylenically unsaturated resin compound and a monoethylenically unsaturated diluent are cured to form compositions containing essentially no polymerizable ethylenically unsaturated compounds by:(a) admixing with the composition at least about 0.1 weight percent, based upon the weight of the composition, of an electron-rich, aromatic promoter; and(b) exposing the admixture of (a) to a sufficient amount of radiant energy to essentially completely polymerize the ethylenically unsaturated components of the composition.For example, a composition consisting of the diacrylate of a bisphenol A and epichlorohydrin condensation adduct in a dicyclopentadiene acrylate diluent is vinyl polymerized in the presence of 1,4-dimethoxybenzene with electromagnetic radiation such that less than 0.2 percent unreacted dicyclopentadiene acrylate monomer is present in the resulting cured composition.
