Abstract
Procédé de préparation de colorants azoïques. On copule le diazoïque d'une amine hétérocyclique aromatique de la série du thiazole, du benzothiazole, du benzo-iso-thiazole; du thiadiazole, du triazole ou du thiophène, avec un copulant ou, dans un solvant ou milieu dispersant constitué d'un mélange de 90 à 15 % en poids d'un alcool aliphatique comportant, dans sa chaîne, de 4 à 6 atomes de carbone et ayant une solubilité dans l'eau, à 15 degrés C, d'au plus 15 % en poids et de 10 à 85 % en poids d'eau, à des températures comprises entre environ 0 et 80 degrés C, en présence d'un acide. On obtient ainsi, avec un bon rendement, des colorants très purs.
