Abstract: Compatibility agents were developed for improving the compatibility and stability of mixtures of liquid fertilizers and liquid or wettable powdered pesticides. These compatibility agents contain water, a low alkanol and an alkylaryl polyoxyethylene glycol phosphate ester. The compatibility agent is used at a preferred concentration range of 0.1 to 0.4% of the fertilizer solution. The preferred compatibility agent not only improves the compatibility of liquid fertilizer-pesticide mixtures, but also results in uniform and stable mixtures ensuring accurate pesticide applications. The preferred compatibility agent is a mixture containing about 16% water, about 20% methanol and about 64% of an octylphenol polyoxyethylene glycol phosphate ester.
Abstract: The compounds are amino- or cyano-bearing dihydroquinolines, which have either of the combinations of (a) 2-amino, 3-carboxylic and 4-oxo functions, or (b) 2-oxo, 3-cyano and 4-hydroxy functions, and may be optionally substituted at 1 or 2 of the 5, 6, 7 or 8 positions, eg 1-allyl-2-amino-1,4-dihydro-6,7-dimethoxy-4-oxo-quinoline-3-carboxylic acid ethyl ester, and 1-allyl 3-cyano-1,2-dihydro-4-hydroxy-6,7-dimethoxy-2-oxo-quinoline. The compounds are useful as pharmaceuticals.
Abstract: The preparation of vincadifformine and some derivatives thereof for use as a starting material for synthesis of the corresponding vincamine derivatives or for synthesis of bisindole alkaloids having clinically important antitumor properties.
Abstract: Quinoline derivatives, especially those of the formula ##STR1## wherein X represents halogen, nitro or CF.sub.3,Z represents hydrogen, alkyl or aryl,Y represents hydrogen, OH, CN, COR or SO.sub.3 H,R represents alkyl, alkoxy or aryl andn represents an integer from 0 to 4,are obtained in high yields when corresponding aromatic orthodichloromethyl isocyanates are converted by hydrolysis and decarboxylation into the corresponding ortho-aminoaldehydes and these are subjected to a condensation reaction with carbonyl compounds containing an active .alpha.-methylene group.The process products are starting materials for dyestuffs, insecticides and others.
