    • The invention provides a process for forming an acetoacetarylide slurry, comprising: (a) adding a solid acetoacetarylide to a homogenizer; (b) homogenizing the acetoacetarylide in the presence of water and one or more additives to form an acetoacetarylide slurry. The invention further provides a process for forming an acetoacetarylide-based pigment, comprising: (a) reacting a diketene with an amine to form an acetoacetarylide slurry; (b) separating the acetoacetarylide as a solid from the acetoacetarylide slurry; (c) adding the acetoacetarylide solid to a homogenizer; (d) homogenizing the acetoacetarylide in the presence of water and one or more additives to form an acetoacetarylide slurry; (e) pumping the acetoacetarylide slurry to a reaction tank; (f) adding an alkali or alkaline earth metal base to the slurry; (g) adding an acid to form a precipitate of the acetoacetarylide; and (h) reacting the precipitate with a diazonium salt, thereby forming an azo pigment. This invention also includes the pigments and intermediates thereto formed by the above processes.
    • 本发明提供一种形成乙酰乙酰芳胺淤浆的方法,包括:(a)将固体乙酰乙酰芳胺加入均化器中; (b)在水和一种或多种添加剂存在下均化乙酰乙酰芳胺以形成乙酰乙酰芳胺浆液。 本发明进一步提供了形成乙酰乙酰芳胺基颜料的方法,包括:(a)使双烯酮与胺反应以形成乙酰乙酰芳胺浆液; (b)从乙酰乙酰芳胺淤浆中分离乙酰乙酰芳胺固体; (c)将乙酰乙酰芳胺固体加入均化器中; (d)在水和一种或多种添加剂的存在下均化乙酰乙酰芳胺以形成乙酰乙酰芳胺浆液; (e)将乙酰乙酰芳胺淤浆泵送至反应罐; (f)向浆料中加入碱金属或碱土金属碱; (g)加入酸以形成乙酰乙酰芳胺的沉淀物; 和(h)使沉淀与重氮盐反应,从而形成偶氮颜料。 本发明还包括通过上述方法形成的颜料及其中间体。
