摘要： The invention provides a process for the fine division of pigments which comprises dissolving coarsely crystalline crude pigments in a solvent and precipitating them with a liquid precipitation medium by spraying the pigment solution and the precipitation medium through nozzles to a point of conjoint collision in a reactor chamber enclosed by a housing in a microjet reactor, a gas or an evaporating liquid being passed into the reactor chamber through an opening in the housing for the purpose of maintaining a gas atmosphere in the reactor chamber, and the resulting pigment suspension and the gas or the evaporated liquid being removed from the reactor through a further opening in the housing by means of overpressure on the gas entry side or underpressure on the product and gas exit side.

摘要： Iodogallium phthalocyanine and bromogallium phthalocyanine having novel crystalline forms characterized by X-ray diffraction patterns according to CuKnull characteristic X-ray diffraction method and exhibiting excellent zirconium phthalocyanine can be obtained through appropriate selection of a reaction solvent, followed by milling or stirring in an appropriate solvent. For example, null-chloronaphthalene is a suitable solvent for reaction between phthalonitrile and gallium triiodide or tribromide to provide iodogallium phthalocyanine or bromogallium phthalocyanine. Reaction of chlorogallium phthalocyanine or hydroxygallium phthalocyanine with hydroiodic (or hydrobromic) acid is also effective for providing a novel crystal form of iodo-(or bromo-)gallium phthalocyanine. Zirconium phthalocyanine exhibiting good electrophotographic performances can be obtained through a similar process.
