    Abstract: 1,139,075. Filter cake demoisturing. FARBWERKE HOECHST A.G. 11 Feb., 1966 [12 Feb., 1965], No. 6163/66. Heading C4P. [Also in Division B1] Azo dyestuffs, in the form of cake from a filter press, are further demoistured by kneading in a container 3 having a pervious surface 2 on which a stationary layer of dyestuff is maintained 0À5 to 8 mm. thick by suitable spacing of roll 1, while maintaining a pressure difference across the said layer to expel liquid therethrough, the kneading consisting of alternate periods of fast and slow action with a speed ratio in the range 1/3 to 1/20 between them until no more liquid is obtained. The roll 1 describes a sun-and-planet movement round container 3, the two rotations being independently driven by variable speed motors (speeds given). Dyestuff is delivered by inlet 6, which may be subsequently used to apply pressure gas, and outlet 16 is connected to an air suction pump. Treated dyestuff is discharged by screw extrusion press 4, 5, whose tapered outlet may prevent discharge of excessively wet material. The apparatus may be used to treat the dyestuffs further, by adding washing water or other liquids able to displace the residual liquid, mixing therewith and again demoisturing. The spacing between roll 1 and fine mesh fabric (30 microns) or perforated surface 2 is adjusted by raising and lowering the drive-shaft 12, by nuts 14, 15.

    Abstract: A dye and pigment dispersion containing a sulfuric acid semiester of the formula

    IN WHICH X is ethylene or propylene, R1 alkyl of 4 to 14 carbon atoms, R2 hydrogen or alkyl of 4 to 14 carbon atoms, n an integer of 2 to 25, z zero or an integer of 1 to 8 and Me hydrogen, alkali, alkaline earth metal, an ammonium ion or a radical of an organic base, and a process for preparing it by grinding the dye or pigment in the presence of an aqueous solution of said sulfuric acid semi-ester. The dispersing agents obtained have a good dispersing effect and tinctorial strength and give a neutral reaction in contrast to most of the known anionic dispersing agents.

    Abstract: A dispersion of a disperse dyestuff which contains, as the dispersing agent, a sulfosuccinic acid semi-ester of the formula A-(X - 0)n-CO-B (1) wherein B is A is an alkylphenoxy of the formula OR A GROUP OF THE FORMULA X is ethylene or propylene, R1 is saturated alkyl having from four to 14 carbon atoms, R2 and R3 each are hydrogen or saturated alkyl having from six to 14 carbon atoms, R4 is a saturated alkyl of six to 14 carbon atoms, R4 is a saturated alkyl of 64 to 14 carbon atoms, n is an integer from 2 to 25, z is an integer from 1 to 9 and Me is hydrogen, alkali metal or an alkaline earth metal ion. These dispersing agents show a distinctly improved dispersing effect and effect a higher tinctorial strength so that smaller amounts of the dispersing agent are necessary as compared with other dispersing agents known hitherto.
