Abstract: Prodn. of halo-substd. isatoic anhydrides of formula (I) is claimed (where Y is H or 1-4C alkyl, and R1,R2 and R3 are H, Cl, Br, NO2, 1-4C alkoxy, 1-4C alkyl, CF3, 1-4C alkanoylamino, carbamoyl, mono- or di(1-4C alkyl) carbamoyl, sulphamoyl or mono- or di(1-4C alkyl) carbamoyl, provided that at least one of R1, R2 and R3 is/are Cl or Br). Process comprises halogenating corresponding isatoic anhydrides in which at least one of R1, R2 and R3 is/are H with at least 0.5 molar proportions of elementary chlorine or bromine in the presence of chlorosulphonic acid at -10 to +100 deg.C.

Abstract: Preparation of water-soluble, amino group-containing condensation or addition product with an increased dewatering and retention effect when used in the production of paper, comprises: (a) subjecting aqueous solutions of the condensation or addition products listed below, to an ultrafiltration step using membranes in order to separate 5 - 95 wt.% of the products as a permeate, and optionally (b) recovering the amino-group containing water-soluble products with enhanced dewatering and retention properties from the retentate. The condensate and addition reaction products are selected from: (a) reaction products of alkylene diamines, polyalkylene polyamines and/or ethylene imine-grafted polyamidoamines with cross-linking agents (CLAs) containing \- 2 functional groups ; (b) Michael reaction addition products of alkylene diamines, polyalkylene polyamines and/or ethylene imine-grafted polyamidoamines, or monoethylenic unsaturated carboxylic acids or their salts, esters, amides or nitriles with at least bifunctional CLAs; (c) amidised polyethylene imines (prepared by reacting polyethylene imines with monobasic carboxylic acids or their esters, anhydrides or amides), optionally reacted with CLAs containing \- 2 functional groups; (d) polyethylene imines, quaternary polyethylene imines, (cross-linked) phosphono-methylated polyethylene imines and/or carboxymethylated (by chain extension reaction) polyethylene imines, or (e) cross-linked alkoxylated polyethylene imines, cross-linked quat. polyethylene imines, cross-linked phosphono-methylated polyethylene imines and/or carboxymethylated (by chain extension reaction) polyethylene imines.

Abstract: Isoindoline colourants of the general formula (I) in which Y represents a radical of the formula in which R denotes cyano, carbamoyl, N-C1- to C4-alkylcarbamoyl, N-phenyl-carbamoyl, 2-quinazolonyl, 2-quinoxalinonyl, 2-benzimidazolyl or 2-benzothiazolyl and, independently of one another, the rings A and B, the phenyl rings in R and the benzene rings of the heterocycles in R are optionally substituted by non-solubilising groups. The colourants (I) are blue to black pigments for colouring coatings, printing inks and plastics. The colourings have high fastness properties.

Abstract: Molecular weight distribution of an ethyleneimine polymer is narrowed by subjecting a solution of the polymer to ultrafiltration, removing 5-95 wt.% of the polymer as permeate, and optionally isolating the remaining polymer from the retentate.
