    • A process for the production of a phthalocyanine pigment having a clear color tone, a high tinting strength and a finely milled structure by an efficient and economical process, in which the pigmentation from a phthalocyanine crude can be carried out without removing an aromatic hydrocarbon solvent used in the synthesis of the phthalocyanine crude, the process comprising thes steps of(a) reacting phthalic anhydride or its derivative, urea or its derivative and a catalyst in an organic solvent to synthesize a phthalocyanine crude,(b) wet-milling a slurry of the synthesized phthalocyanine crude in the presence of a milling medium without removing the aromatic hydrocarbon solvent, and(c) removing the organic solvent from the slurry of the milled product, purifying the milled product and drying the milled product with a spray type dryer.
    • 一种通过有效和经济的方法生产具有清晰色调,高着色强度和精细研磨结构的酞菁颜料的方法,其中可以在不除去使用的芳族烃溶剂的情况下进行来自酞菁粗品的着色 在酞菁粗品的合成中,该方法包括以下步骤:(a)使邻苯二甲酸酐或其衍生物,脲或其衍生物和催化剂在有机溶剂中反应以合成酞菁粗品,(b)湿法研磨 合成的酞菁粗品,在研磨介质存在下,不除去芳族烃溶剂,和(c)从研磨产物的浆料中除去有机溶剂,纯化研磨产物并用喷雾式干燥器干燥研磨产物。
