    Abstract: 1,145,256. Preparation of copper phthalocyanines. BADISCHE ANILIN- & SODAFABRIK A.G. 24 June, 1966 [25 June, 1965], No. 28370/66. Heading C4P. Copper phthalocyanines are prepared by reacting together at temperatures up to 220‹ C. a phthalodinitrile, e.g. tetrachlorophthalodinitrile; a copper salt, e.g. sulphate, acetate or chloride; an inert solvent, e.g. chlorobenzenes, nitrobenzenes and C 8 , C 9 and C 12 aliphatic alcohols; a nitrogen base, e.g. ammonia and tertiary aromatic bases such as pyridine and quinoline; and as a catalyst material a compound, e.g. an oxide, oxyacid or a salt thereof, a halide or carbonyl compound of an element having an atomic number of 22-24, 26-28, 30, 32-34, or 40-42. A large excess of nitrogen base may replace the solvent.

    Abstract: A procedure and apparatus for charging and emptying the drying trays in a drying box containing pumpable, solvent-moist starting materials and end products which can be conveyed pneumatically, in which procedure, for filling, the drying trays are closed by means of cover plates and the solvent-moist starting materials are pumped into the filling spaces which are thus formed, these spaces being opened on commencing the drying process, and being closed again following completion of this process, after which the end products are conveyed away from the filling spaces by pneumatic means. This procedure enables drying boxes to be employed for drying even pumpable, solvent-moist products, the recommendations relating, respectively, to explosion protection and to maximum permissible concentrations of toxic materials at workplaces, being complied with, while the operations of charging and emptying the drying boxes are, at the same time, carried out by mechanical means, and hence at lower cost.

    Abstract: Stable, fluid formulations contain (a) finely divided iron cyano complexes, iron-III oxides or iron-III oxide hydrates, (b) one or more C6-C18-alkylbenzenesulfonic acid, (c) one or more compounds which are obtained by Mannich condensation from 2-hydroxynaphthalene, which may or may not contain 1 or 2 additional beta -hydroxyl groups, formaldehyde and primary or secondary aliphatic, cycloaliphatic or aromatic monoamines, diamines, triamines or polyamines or 5- or 6-membered heterocyclic compounds, and which contain from 1 to 6 beta -hydroxynaphthyl groups, and (d) one or more organic liquids, the ratio of (b):(c) being from 1:8 to 2:1 and the amount of (c) being from 10 to 20% by weight, based on (a). The formulations are fluid or pourable at pigment concentrations of from 20 to 55% by weight and give very deeply colored, very glossy finishes.
