Abstract: Anti-Microbial Quaternary Ammonium Co-Polymers formed by the condensation of at least two di-functional tertiary amines and a molar quantity of 1,4-dihalo-2-butene that is equal to the molar sum of the di-functional tertiary amines in the mixture.

Abstract: The industrial herbicide 5-(1,3,3-trimethylureido)-N,N-dimethyl-1,3,4-thiadiazole-2-sulfonamide and other compounds of similar structure may be made by a novel procedure in which the first step is the oxidative chlorination of a 2-alkylamino-5-mercapto-1,3,4-thiadiazole to yield the corresponding sulfonyl chloride. The subject compound which possesses five methyl substituent groups is more effective as a herbicide than compounds which contain other alkyl substituents or a lesser number of methyl substituents.

Abstract: N-2-(6-hydroxybenzothiazolyl)-N'-phenyl (or substituted phenyl) ureas, useful as immune regulants.

Abstract: Doxycycline aceturate is prepared by reacting doxycycline with aceturic acid in a solvent. The compound is useful for the same pharmacological purposes as doxycycline and is more soluble in water or aqueous solvents so that it is more suitable for parenteral administration.

Abstract: Process for the preparation of an amino-pyrazine falling within the formula: ##SPC1##In which R.sub.1 and R.sub.2 each represent a hydrogen atom, or an alkyl or aryl group, or together with the carbon atoms of the pyrazine ring form a cyclic hydrocarbon having 5 to 7 carbon atoms, and X represents a cyano, carboxy, carbonamido, alkoxy-carbonyl or aryloxycarbonyl group which comprises subjecting a 2-aza-1,3-butadiene of the general formula: ##EQU1## wherein Z and Zi each represent an alkyl group or together with the nitrogen atom form a heterocyclic compound possibly containing another hetero atom to the action of ammonia and reacting the 4-amino-2-aza-1,3-butadiene of formula ##EQU2## thus obtained with a basic agent: novel compounds of formula VIII in which R.sub.1 and R.sub.2 each represent a different alkyl or aryl group or together with the carbon atoms of the pyrazine ring form a cyclic hydrocarbon containing 5 to 7 carbon atoms: intermediate compounds of formula: ##EQU3## wherein X, R.sub.1 and R.sub.

Abstract: An improved process for the preparation of unsaturated terpene alcohols such as myrcenol and cis and trans ocimenol is described. Acyclic terpene allylic halides are reacted with a tertiary amine of the formula hereinafter described to form the corresponding quaternary ammonium salt which is then acidified to remove the ethylenic unsaturation between the 6th and 7th carbon atom and adding a hydroxy substituent on the 7th carbon atom of the terpene halide salt. The hydrated terpene ammonium halide salt is made neutral and thermally decomposed into the unsaturated terpene alcohols. Myrcenol and ocimenol cis and trans are useful for their fragrance and aroma in perfumery and cosmetic manufacture.

Abstract: N-2-(6-hydroxybenzothiazolyl)-N'-phenyl (or substituted-phenyl) ureas are prepared by reacting 2-amino-6-hydroxybenzothiazole with 1-2 moles of phenyl (or a substituted phenyl) isocyanate and then hydrolysing any 6-phenylcarbamoyloxy compound thus produced to the corresponding 6-hydroxy derivative.

Abstract: Disclosed are a group of chemical compounds which have been found to be useful in the area of flavor-note alteration.
