Abstract: A series of 5-endo-carbamoyloxy-N-[amino(lower)-alkyl]bicyclo[2.2.1]heptane-2,3-di-end o-carboxylic acid imides have been found to possess unique prophylactic and therapeutic activity as anti-arrhythmia agents. An example of such a compound possessing excellent activity is 5-endo-phenylcarbamoyloxy-N-(3-dimethylaminopropyl)bicyclo[2.2.1]heptane-2 ,3-diendo-carboxylic acid imide hydrochloride.
Abstract: A novel class of monomeric emulsion stabilizers consists of certain types of ethylenically-unsaturated radicals covalently linked to a quaternary nitrogen atom which in turn is covalently linked to a lipophilic radical. Such monomers will polymerize with other ethylenically-unsaturated radicals forming self-stabilized, surfactant-free polymeric dispersions.

Abstract: Organic compounds are prepared by a novel method of conjugate addition in which a donor compound including a carbanion derived from an activated methylidyne group is treated with an acceptor compound including a carbon-carbon unsaturated bond conjugated with an onium ion derived from a polar functional group. The method has particular application as a step in the production of novel intermediates and novel pharmacologically active compounds as disclosed in the Applicants' co-pending application of even date.
Abstract: Compounds having a mercaptoethyl group are prepared by reacting an aqueous thiocyanate solution with ethylene oxide in the presence of an inert water immiscible organic solvent to form ethylene sulfide and then reacting the organic phase with a polar organic compound, preferably a secondary amine.

Abstract: The present invention relates to amine, alkali metal and alkaline earth metal salts of N-benzene sulfonyl carbamic acid esters and to lower alkenyl N-benzene sulfonyl carbamates. These compounds are useful as herbicides.
Abstract: The production of anthraquinone-1-carboxylic acid by reacting a benzoyl halide with a tert.-butylxylene in the presence of ferric chloride, adding aluminum chloride, oxidizing the dimethylbenzophenone formed and cyclizing the resulting benzophenonedicarboxylic acid. The product is a starting material for the production of dyes and pesticides.
Abstract: A process for the manufacture of aminoanthraquinones from nitroanthraquinone, wherein the nitroanthraquinones are treated with ammonia in dipolar aprotic solvents that are inert towards ammonia and nitroanthraquinones.
Abstract: Improved curing agents having long pot life for use with urethane elastomers are prepared by reacting orthochloroaniline, an ester of anthranilic acid, and formaldehyde in selected molar ratios in an acid medium.
Abstract: Pure 1-nitro-anthraquinone is produced by nitrating anthraquinone in aqueous hydrogen fluoride containing about 5 - 30 weight percent of water with nitric acid as nitrating agent at about 0.degree. - 150.degree.C preferably 20.degree. - 70.degree.C.

Abstract: Addition of non-transitional bismuth ion to oxidation catalysis provided by heavy, transition metal-bromine ion combination containing both cobalt and manganese ions uniquely increases catalytic activity of said combination for converting ortho substituted methyl groups to corresponding carboxylic acid groups on benzene nucleus by a factor much greater than by the addition of equivalent amount of such high catalytically active heavy, transition metal as cobalt and manganese. Such greater catalytic activity is manifested by longer sustained initial rapid rate of oxygen consumption and higher o-dicarboxybenzene yield.
Abstract: Process for the manufacture of pure 1-nitroanthraquinone, characterised in that a nitroanthraquinone mixture obtained by nitration of anthraquinone in the presence of inorganic acids and, optionally, lowering the molar fraction of the acids in the reaction mixture after isolation of the reaction products which have precipitated and, optionally, further measures, is subjected to a rectification.

Abstract: A two-stage process for producing para-aminobenzoic acid by first reacting certain lower alkyl or glycol monoesters of terephthalic acid or specific salts thereof or mixtures thereof with ammonia in liquid phase at elevated temperatures and pressures to obtain a terephthalic acid monoamide intermediate, removing substantially all ammonia from this intermediate and then converting it into the para-aminobenzoic acid product by the Hofmann reaction, preferably using a sodium hypochlorite solution. The para-aminobenzoic acid, either as the free acid or in the form of its salts or esters is a known product having many uses.
