Abstract: Phenylthioaralkylamines and 2-phenylthiobenzylamines are prepared by reaction of the corresponding phenylthiobenzoyl chloride or homologs thereof with ammonia or an amine to produce the corresponding phenylthiobenzamide or N-substituted or N,N-disubstituted derivative thereof followed by reduction with lithium aluminum hydride to produce the corresponding phenylthiobenzylamine or the N-substituted or N,N-disubstituted derivative thereof. The compounds are also prepared by reaction of the corresponding phenylthiobenzyl halide with ammonia or a selected amine. The compounds are active as antiarrhythmics.

Abstract: The invention is concerned with novel 16-aryloxy-, 16-alkoxy-, 16-arylthio- and 16-alkylthio-8-aza-9-dioxothia-11,12-seco-prostaglandins and processes for their preparation. These novel compounds are useful as pharmaceuticals since they can be used in animals for estrus synchronization and treatment of infertility due to persistence of luteal function.

Abstract: Methods of using aqueous hydraulic cement compositions containing polyamido-sulfonic compounds as flow-property-improving and turbulence-inducing additives are disclosed.

Abstract: Novel cyano substituted (3-loweralkylamino-2-acyl-O-propoxy)pyridines, their pharmaceutically acceptable salts and their preparation are disclosed. The pyridines are vasodilators having antihypertensive activity of rapid onset and extended duration and reduced tendency to cause undesirable tachychardia; they are also .beta.-adrenergic blocking agents.

Abstract: Novel pharmaceutical compositions comprising hydrazino-phenylpropionic acid decarboxylase inhibitors and certain benzimidazole and benzoxazole alanines are disclosed. The compositions have enhanced hypotensive activity.

Abstract: (2-oxo-3-butenyl)dimethylamine monomers which may be used in the preparation of high molecular weight water-soluble cationic polymers which may be used as flocculants, drainage and retention aids, or conductive polymers.

Abstract: Cationic, electrically conductive polymers are mixed with multifunctional anionic compounds and/or anionic polymers to form a polysalt complex which exhibits markedly improved properties. Specifically, solvent holdout to parafinic solvents and to toluene are considerably improved, and the tackiness of the resulting film is notably decreased. The polysalt products also exhibit very good filmability on plastic substrates whereas the cationic polymer alone normally forms very poor films on such substrates.

Abstract: Methods of using aqueous hydraulic cement compositions containing phosphonobutane tricarboxylic acid as a flow-property-improving and turbulence-inducing additive are disclosed.

Abstract: Use of oil soluble cationic polymers as flocculants for the purification of used motor oil. Polymers useful in the process of the instant invention include oil soluble polymers such as fatty acid salts of cationic polymers.

Abstract: Methods of using aqueous hydraulic cement compositions containing sulfonated copolymers of styrene-maleic anhydride as flow-property-improving and turbulence-inducing additives are disclosed.

Abstract: This invention relates to 8-aza-9-oxo(and dioxo)-thia-11,12-secoprostaglandins and processes for their manufacture. These compounds have prostaglandin-like biological activity and are particularly useful as renal vasodilators, for the prevention of thrombus formation, to induce growth hormone release, and as regulators of the immune response.

Abstract: Solid metal carboxylate composition which is used to detect the presence of sulfide in high pH aqueous streams.

Abstract: This invention relates to novel 9-thia-, 9-oxothia-, and 9-dioxothia-11-oxo-12-azaprostanoic acid compounds, salts, and derivatives thereof and also to processes for the preparation of such compounds. These compounds have prostaglandin-like biological activity and are particularly useful as renal vasodilators, as platelet aggregation inhibitors, and for the treatment of certain autoimmune diseases.
