Abstract

1497000 Fluorescent dyes MONTEDISON SpA 21 April 1976 [24 April 1975 (2)] 16171/76 Heading C4P The invention comprises fluorescent dyes having the general formula wherein Z is a nitrogen or carbon atom, X is H or is additionally bromine when Z is carbon, Y is methoxy or ethoxy or is additionally H when Z is a carbon atom, and X' is -NH- or additionally -S- when Z is nitrogen. They are prepared by reacting a halogen substituted compound of the general formula wherein X, Y and Z are as above and A is Cl or Br with a compound of the general formula wherein X' is as above in an aprotic dipolar solvent at 80-140‹ C. in presence of an acid acceptor. The solvents include dimethylformamide, dimethylacetamide, dimethylsulphoxide, 1-methylpyrrolidin-2-one, hexamethylphosphotriamide and mixtures thereof. Acid acceptors used are sodium and potassium carbonates, pyridine and piperidine. The dyes are used to bulk dye polystyrene, polymethylmethacrylate, rigid P.V.C. polyethylene, acrylonitrile-butadiene-styrene copolymers and polycarbonates, and to colour mineral oils.
