摘要： In the methylation of 4-amino-6-t.-butyl-3-mercapto-1,2,4-triazin-5-one to produce 4-amino-6-t.-butyl-3-methylmercapto-1,2,4-triazine-5-one using methyl bromide, the reaction is run in the absence of air whereby product coloration is avoided. Desirably considerable agitation is employed along with recycle and especially with an emulsifying agent which markedly speeds up the reaction. Measures such as operating under a slight vacuum and recycle of unused methyl bromide and mother liquor are employed to improve the yield and to avoid the problems of discharging the bromides to the environment.

摘要： Compressed air is introduced into a feed pipe system for transporting powdery or granular material in order to promote dense flow conditions. Variable or fixed size restrictions with decreasing size of blocking surface in the direction of the material flow equalize the amount of air entering the feed pipe along its entire length. The compressed air is introduced into the feed pipe through porous materials positioned at least in the region of the restrictions.

摘要： Dichloropinacolone is produced by introducing into pinacolone twice the molar amount of chlorine, the exothermic reaction mass being cooled initially to maintain the temperature below about 50.degree. C until about 60 to 80% of the chlorine has been introduced, and then heating the reaction mass to a temperature above 50.degree. C during introducing of the remainder of the chlorine, thereby to produce dichloropinacolone, and terminating chlorine introduction when the dichloropinacolone content of the reaction mass is at least about 97%. The molten product is added to an aqueous solution of an alkali maintained at a temperature of at least about 50.degree. C, the alkali being present in more than three times the molar amount of the dichloropinacolone. To the resulting solution of a salt of 3,3-dimethyl-2-hydroxy-butyric acid, brought to a pH of about 9 to 12, there is added approximately the stoichiometric amount of potassium permanganate. Solid MnO.sub.2 precipitates out and is separated from the substantially pure dissolved salt of 3,3-dimethyl-2-oxo-butyric acid. The product is a known compound suited for further syntheses.

摘要： The invention concerns a new method for producing optically active 1-phenylethylamines, wherein (a) racemic 1-phenylethylamines are reacted with (S)-(-)-N-phenylcarbamate lactic acid in the presence of an aliphatic or aromatic hydrocarbon and in the presence of a lower aliphatic alcohol, wherein the reaction components are measured so that for every mole of racemic amine, between 0.25 and 0.5 mole of (S)-(-)-N-phenylcarbamate lactic acid are present, the reaction mixture is then concentrated at a liquid-phase temperature of up to 40.degree. C., the resulting solid product is separated, treated with diluted, aqueous alkaline lye in the presence of a hydrocarbon, and the respective (R)-amine is isolated by distillation from the organic phase, and if necessary, (b) the mother liquor remaining after the separation of the solid product is reacted in the presence of a lower aliphatic alcohol with (S)-(-)-N-phenylcarbamate lactic acid, wherein the reaction components are measured so that the molar quantity of (S)-(-)-N-phenylcarbamate lactic acid is twice as great as the quantity of (R)-amine still remaining in the mother liquor, the reaction mixture is then concentrated at a liquid-phase temperature of up to 40.degree. C., the resulting solid product is separated and the (S)-amine is isolated by distillation from the mother liquor.

摘要： A process for the treatment of waste water obtained in the condensation of thiocarbohydrazide and an aqueous solution of an .alpha.-keto carboxylic acid such as, e.g., 3,3-dimethyl-2-oxo-butyric acid, which comprises mixing said waste water with a water-immiscible ketone, preferably selected from the group consisting of methyl isobutyl ketone, cyclohexanone and pinacolone, said ketone being employed in an amount sufficient to form two phases, separating said two phases, and discharging as waste the aqueous phase. Advantageously the pH of the waste water is no higher than about 6 and its temperature is 20.degree. to 50.degree. C. The organic phase comprises the ketone containing dissolved therein an adduct of the ketone with thiocarbohydrazide and/or similar amino materials originally present in waste water. The excess of the ketone may be recovered from the organic phase by distillation, or the organic phase may be treated with alkali to effect hydrolysis of such adducts, the ketone separated and recycled and the amino materials recovered.
