    摘要： 2-PYRAZOLINE-1-CARBOXAMIDE SULFONAMIDE DERIVATIVES HAVING THE GENERAL FORMULA:

    (3-R,4-R1,5-R2,5-R3-2-PYRAZOLIN-1-YL)-CO-NH-SO2-(1,4-

    PHENYLENE)-Z

    IN WHICH Z IS HYDROGEN, HALOGEN OR LOWER ALKYL, AND R, R1, R2, R3 ARE EACH HYDROGEN OR LOWER ALKYL. THESE SULFONAMIDE COMPOUNDS HAVE A HYPOGLYCEMIC EFFECT AND ARE OBTAINED BY REACTING A 2-PYRAZOLINE DERIVATIVES SUCH AS HN-CR2R3-CHR1-CR=N WITH AN ARYLSULFONYLUREA SUCH AS Z-C2H4EO2NHCONH2 OR WITH AN ARYLSULFONYLISOCYANATE SUCH AS Z-C6H4SO2NCO OR BY THE THERMAL DECOMPOSITION OF THE MOLECULAR COMBINATION OF THE 2PYRAZOLINE DERIVATIVE AND THE ARYSULFONYLUREA.

    摘要： The present invention provides compounds of the formula:

    WHEREIN Ar represents an aromatic residue which may be substituted by substituents not having a chromophoric or anionic character, R1 and R2 represent alkyl groups containing one to five carbon atoms, which may be the same or different, n is 2 or 3 and X represents a monovalent anion or its equivalent. It also relates to the preparation of such compounds and to their use in optical brightening or whitening fibres based on polymers or copolymers of acrylonitrile.
