    Abstract: Process for the dyeing and printing of textile materials made from polymers or copolymers of acrylonitrile by using dyestuffs of the general formula

    IN WHICH R1 represents an alkyl, aralkyl, aryl or heterocyclic radical which may be substituted R2 represents hydrogen or an alkyl or aralkyl radical which may be substituted, Q represents an aromatic or heterocylic radical which may be condensed with the benzene nucleus b, and X represents an anion and the benzene radicals a and b as well as the radical Q may contain further non-ionogenic substituents. The dyeings and prints thus obtained show a good fastness to light, wet processing, washing, fulling, over-dyeing, to chlorine, to perspiration and to carbonizing as well to decatizing, steaming, ironing, rubbing and to solvents.

    IN WHICH R STANDS FOR A LOWER ALKYL GROUP WHICH MAY BE SUBSTITUTED, R1 AND R2 EACH STANDS FOR A HYDROGEN ATOM OR A LOWER ALKYL GROUP WHICH MAY BE SUBSTITUTED AND WHICH MAY FROM TOGETHER WITH THE NITROGEN ATOM ALSO A HETEROCYCLIC RADICAL, R3 STANDS FOR A HYDROGEN ATOM OR A LOWER ALKYL GROUP WHICH MAY BE SUBSTITUTED, R4 STANDS FOR A HYDROGEN ATOM, A LOWER ALKYL GROUP WHICH MAY BE SUBSTITUTED, AN ARYL GROUP WHICH MAY BE SUBSTITUTED, OR TOGETHER WITH THE NITROGEN ATOM AND R3 OR THE BENZENE NUCLEUS R4 MAY FORM A HETEROCYCLIC RADICAL, AND X STANDS FOR AN ANION, AND THE BENZENE NUCLEUS A MAY CARRY FURTHER NONIONIC SUBSTITUTENTS OR A FUSED BENZENE NUCLEUS. THE NOVEL DYESTUFFS ARE SUITABLE FOR THE DYEING OR PRINTING OF TANNINED CELLULOSE FIBERS, SILK, LEATHER OR FULLY SYNTHETIC FIBERS, SUCH AS ACETATE RAYON, POLYAMIDE FIBERS OR ACID-MODIFIED POLYAMIDE OR POLYESTER FIBERS, ESPECIALLY OF FIBERS CONTAINING POLYACRYLONITRILE OR POLYVINYLIDENE CYANIDE. THE DYEINGS PRODUCED ON THESE FIBERS ARE MOSTLY VERY BRIGHT AND HAVE A GOOD TINCTORIAL STRENGTH AS WELL AS, IN GENERAL, GOOD FASTENESS PROPERTIES TO LIGHT AND WET PROCCROSS-DYEING, CARBONIZING, TO THE ACTION OF CHLORINE AND TO PERSPIRATION.

    Abstract: An improved process for isolating 2-hydroxynaphthalenecarboxylic acids from reaction mixtures of the alkali metal salts of the 2-hydroxynaphthalene with carbon dioxide had been found which comprises diluting with water the reaction mixture which contains the di-alkali metal salt of 2-hydroxynaphthalenecarboxylic acid and 2-hydroxynaphthalene, while keeping the mixture at a temperature of at least 80 DEG C, then adjusting the pH-value to about 6 to 7 by means of aqueous mineral acid, separating the lower phase at at least 80 DEG C, cooling the upper phase to about 15 DEG to 25 DEG C, separating the 2-hydroxynaphthalene, then adjusting the pH-value to about 1 to 2 by means of aqueous mineral acid and isolating the separated 2-hydroxynaphthalenecarboxylic acid. By this novel process, work intensive operations, expensive technical apparatuses which are suspectible to repairs, solvents which do not participate directly in the reaction and therewith complicated regenerations, as known from the present art, are completely avoided. It permits clear and very easy separation of the reaction products at only one and the same stage in the process and allows in advantageous manner continuous operation.
