    Abstract: Process for the preparation of I acid urea of the formula in which 7-amino-4-hydroxynaphthalene-2-sulphonic acid (I acid) is subjected to partial reaction with urea in an inert solvent at a temperature from 100 to 140 DEG C and a pressure from atmospheric pressure to 10 bar, unreacted I acid is precipitated in an acidic medium and removed, and, if appropriate, I acid urea is separated from the resulting neutralised solution by adding salt.

    Abstract: Dicarbamoyl compounds of general formula (I) wherein: m is 1 or 2, n is 0, 1 or 2, W if necessary C2 to C4 alkylene is substituted by C1 to C4 alkyl, chlorine, bromine or phenyl or phenylene optionally substituted by methyl, ethyl, methoxy, ethoxy, hydroxy, chlorine, bromine, hydroxysulfonyl, nitro, amino, acetalamino, or carboxyl; X is C2-C8 alkylene interrupted one to three times, optionally substituted by ether oxygen, imino, phenylimino or C1 to C4 alkylamino or a residue of the formula (II); Z is a residue of formula (III) or (IV); R is hydrogen, C1 to C4 alkyl, phenyl, CH2CH2OH, CH2CH2OSO3H, CH2CH2SO3H or a residue of formula (V); L and L are independently C1 to C4 alkylenes; Y is vinyl or a residue of the formula C2H4Q where Q means hydroxy or a residue separable under alkalic reaction conditions; and Ar means phenyl or naphthyl and both residues can be substituted one to three times by C1-C6 alkyl, C1-C6 alkoxy, fluorine, chlorine, bromine, nitro, amino, hydroxy, hydroxysulfonyl, carboxyl, C1 to C6 alkoxycarbonyl, acetylamino, a residue of formula (VI), (VII), SO2NH-X-S(O)n-Y or S(O)n-Y where R and R are independently hydrogen or C1 to C6 alkyl and n, X and Y have the given meaning. The invention also relates to the use of these compounds for the preparation of fiber reactive dyes.
