Title (EN) METHODS OF MAKING LEUCOINDIGO SALT SOLUTIONS WITH VERY LOW ANILINE CONTENT
(FR) PROCÉDÉS DE FABRICATION DE SOLUTIONS DE SEL DE LEUCO-INDIGO À TRÈS FAIBLE TENEUR EN ANILINE
Abstract:
(EN) Aqueous leucoindigo solution comprising an aromatic amine in the form of aniline or aniline and N-methylaniline, wherein said leucoindigo is in the form of an alkali metal salt; wherein the concentration of the aromatic amine is below 40 ppm determined according to ISO 14362-1:2017(E); and wherein the concentration of the leucoindigo salt is in a concentration range of from 5 to 45 % by weight based on the total weight of the solution, and wherein the solution is stable at a temperature of 23 °C; or wherein the concentration of the leucoindigo salt is in a concentration range of from 45 to 65 % by weight based on the total weight of the solution, and wherein the solution is stable at a temperature of 60 °C.
(FR) L'invention concerne une solution aqueuse de leuco-indigo qui comprend une amine aromatique sous la forme d'aniline ou d'aniline et de N-méthylaniline, ledit leuco-indigo se présentant sous la forme d'un sel de métal alcalin ; la concentration de l'amine aromatique étant inférieure à 40 ppm telle que déterminée selon la norme ISO 14362-1:2017(E) ; et la concentration du sel de leuco-indigo étant dans une plage de concentration de 5 à 45 % en poids sur la base du poids total de la solution, et la solution étant stable à une température de 23 °C ; ou la concentration du sel de leuco-indigo étant dans une plage de concentration de 45 à 65 % en poids sur la base du poids total de la solution, et la solution étant stable à une température de 60 °C.
