Abstract
1438921 Treating crude organic pigments BAYER AG 19 July 1974 [20 July 1973] 32082/74 Heading C4A [Also in Division B1] The physical form of a crude organic pigment is improved with the aid of an inorganic or organic salt which is water-soluble or soluble in aqueous acids or bases and an organic or inorganic liquid which does not significantly dissolve either the pigment or the salt, by subjecting the pigment-salt-liquid mixture to a shear gradient of 300 to 20,000 sec.<SP>-1</SP> for a period of 10 seconds to 15 minutes in a continuously operating kneading apparatus with at least two separated means for adding liquid, the amount of liquid being so chosen that the power taken up by kneading is between 0À4 and 50 kWh/kg. of pigment processed, the temperature in at least part of the kneading zone being between 120‹ and 350‹ C. and the salt being present in an amount between 0À1 and 20 parts by weight relative to 1 part by weight of pigment employed. The kneading apparatus may be a twin-screw or four-screw kneader or a singlescrew kneader which can execute oscillating movements. In the examples a copper phthalocyanine crude pigment, a crude polychlorocopper phthalocyanine, a crude monochlorocopper phthalocyanine pigment, pigment red c.I. 166 and crude perylenetetracarboxylic acid diimide are treated with ground rock salt, diethylene glycol, sodium chloride, ethylene glycol, dodecylamine and aniline.
