    Abstract: A process for preparing perylene-3,4-dicarboximides which bear a sterically demanding substituent on the imide nitrogen atom by reacting a perylene-3,4:9,10-tetracarboxylic dianhydride with a sterically hindered primary amine in a substantially anhydrous reaction medium, which comprises undertaking the reaction in the presence of a tertiary amine, of a solvent based on a cyclic imine or amide and of a Lewis acid as a catalyst.

    Abstract: A process for preparing quaterrylene-3,4:13,14-tetracarboximides of the general formula I in which R, R′ are each independently hydrogen or optionally substituted C1-C30-alkyl, C5-C8-cycloalkyl or aryl or hetaryl; which comprises reacting a perylene-3,4-dicarboximide of the general formula IIa in the presence of a base-stable, high-boiling, organic solvent and of an alkali metal base or alkaline earth metal base, with a perylene-3,4-dicarboximide of the general formula IIb in which X is hydrogen, bromine or chlorine.

    Abstract: The present invention relates to novel reactive dyes of formula I, (I), in which the variable independently denote X hydrogen, NO2, or NR R , Y NR R , OR , SR , or SO2R or a group suitable as a leaving group under the conditions of nucleophilic, aromatic substitution, R to R independently hydrogen, C1-C8 alkyl, C2-C8 alkyl, in which non-adjacent CH2 groups can be replaced by oxygen atoms, imino groups, or C1-C4 alkylimino groups, and/or CH2 groups may be replaced by carbonyl groups, C2-C8 alkenyl, or a group containing an active site or the precursor of an active site, with the proviso that at least one group R to R is present which contains an active site or the precursor of an active site. The present invention also relates to the use of the reactive dyes of Formula I for dyeing substrates containing nucleophilic groups, and to compositions containing at least one reactive dye of formula I.

    Abstract: According to the invention, trisazo dyes are produced by half-side coupling bis-diazotized 4-(4-amino phenylsulfamoyl)aniline to 1-amino-8-hydroxynaphthalene monosulfonic and disulfonic acids, by subsequently coupling diazotized substituted anilines to the other portion of the sulfonic acid, and finally by reacting the second diazonium group on the 4-(4-amino phenylsulfamoyl)aniline with a coupling partner. The inventive trisazo dyes are particularly suited for dying leather and polyamide fibers.

    Abstract: The invention relates to a method for producing 4,4'-dihalogendiphenylsulfone by reacting halogenated benzene with 4-halogenphenylsulfonyl chloride in a liquid phase at high temperature, in the presence of a solid catalyst having acid centers. The method is characterized in that the reaction of 4-halogenphenylsulfonyl chloride with formula (I), in which X is chlorine, bromine or fluorine, with chlorobenzene, bromobenzene, or fluorobenzene, is carried out in the presence of a catalyst which is selected from one of the following groups: K1) catalysts consisting of essentially stratified silicates not having Lewis acids and having proton-saturated negative layer loads, or containing these as a basic component; K2) catalysts consisting of zeolites in the acid H form, or containing these as a basic component; and K3) catalysts consisting of mixed oxides having acidic centres, or containing these as basic components. The mixed oxides consist of a combination of (a) titanium, circonium, hafnium, tin, iron or Cr(III) oxides on the one hand, and (b) vanadium, chromium(VI), molybdenum, wolfram or scandium oxides on the other hand; or the mixed oxides are sulfatized or phosphatized oxides of the group (a), and said mixed oxides are calcined after combination, at temperatures of 450 to 800 DEG C.
