    Abstract: Pyridazinone derivatives of the formula (I) where R1 is alkyl, alkenyl, cycloalkyl or unsubstituted or substituted phenyl, R2 is chlorine or bromine, R3 is hydrogen, alkyl, cycloalkyl or unsubstituted or substituted phenyl and X is SO or SO2, with the proviso that R1 is not methyl when X is SO2, R2 is chlorine and R3 is phenyl, and fungicides containing these compounds.

    Abstract: 1. A process for the preparation of substantially pure pyrazole compounds of the general formula see diagramm : EP0012216,P9,F1 where R is hydrogen, halogen, alkyl of up to 5 carbon atoms, alkoxy of up to 3 carbon atoms, perhaloalkyl of up to 3 carbon atoms or alkoxyalkyl of up to 5 carbon atoms, R**1 is hydrogen, halogen, alkyl of up to 5 carbon atoms, alkoxy of up to 3 carbon atoms, perhaloalkyl of up to 3 carbon atoms or alkoxyalkyl of up to 5 carbon atoms, R**2 is hydrogen, halogen, alkyl of up to 5 carbon atoms, alkoxy of up to 3 carbon atoms, perhaloalkyl of up to 3 carbon atoms or alkoxyalkyl of up to 5 carbon atoms, or R**2 together with R is an ortholinked alkylene chain of up to 6 carbon atoms which is unsubstituted or substituted by alkyl of up to 4 carbon atoms, X is chlorine or bromine, and R**3 and R**4 are identical or different and each is hydrogen, alkyl, alkoxy, alkylthio, carbalkoxy or perfluoroalkyl, in each case of up to 4 carbon atoms, or halogen, phenyl, cyano or carboxyl, from the corresponding crude products, characterized in that the crude products are treated with 30 to 90% by weight aqueous solutions of strong acids, thereafter the aqueous solution is separated off and diluted with water, and the pure product which hereupon precipitates is separated from the aqueous fluid.

    Abstract: O.Z. 0050/033919 of the disclosure: Aromatic azomethines are prepared by reacting anilines with formaldehyde and then removing the greater part of the water by distillation, low-boiling alcohols, in certain amounts, being present during the distillation and, if desired, during the reaction or during a part thereof, The aromatic azomethines obtainable by the novel process are valuable starting materials for the preparation of herbicides, especially pre-emergence herbicides and post-emergence herbicides, fungicides, insecticides, bacteriostatic agents, fungistatic agents and vulcanization accelerators.
