Abstract
1468704 Monoazo dyes HOECHST AG 29 April 1974 [28 April 1973] 18673/74 Heading C4P [Also in Division D1] The dyes of formula in which R 1 and R<SP>1</SP> 1 which may be the same or different are each H, Cl, Br, alkyl, alkoxy, nitro, or sulphonalkyl, R 2 and R 3 which may be the same or different are each H, alkyl, cyanoalkyl, alkoxyalkyl, alkylcarbonylalkyl, alkoxycarbonylalkyl, alkoxycarbonyloxyalkyl, phenyl or phenylalkyl, X is H, Cl, Br, alkyl or alkoxy, Y is H, Cl, Br, alkyl or alkoxy or acylamino, and R is alkylcarbonyl of 2 to 12 carbons, are prepared by acylation of a compound of the above formula in which R is hydrogen with a carboxylic acid ROH in which R is as defined in formula above. Acid halides and acid anhydrides may also be used. The reaction may be effected in an inert organic solvent preferably in presence of pyridine as acid binding agent. Polyester, polyamides, polyolefine, polyacrylonitrile, polyurethane, PVC, polyvinyl acetate, cellulose 2¢- and tri-acetate fibres are dyed by continuous processes in organic solvents.
