    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.
