    摘要: 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.

    摘要: Bei dem vorgeschlagenen Verfahren wird Papierfaserstoff (P), der zumindest teilweise aus bedrucktem Altpapier besteht, mit Wasser (W) suspendiert und sowohl mit Bleich-Hilfsmitteln (CH) als auch Bleich-Chemikalien (OX) vermischt. Die Bleich-Chemikalien (CH) enthalten mit Vorteil molekularen Sauerstoff. Eine intensive mechanische Bearbeitung (2) mit mindestens 20 kWh/to wird vor dem Bleichen (3) vorgenommen, wobei die Bleichdauer mindestens 10 Minuten beträgt und während der Bleiche ein Druck, der über Umgebungsdruck liegt, herrscht. Anschließend wird aus dem gebleichten Stoff der überwiegende Anteil der noch vorhandenen Druckfarbenpartikel entfernt.
