Title (EN) LEUCOINDIGO SALT SOLUTION WITH VERY LOW CONTENT OF ANILINE AND METHOD OF MAKING SAME
(FR) SOLUTION DE SEL DE LEUCOINDIGO PRÉSENTANT UNE TRÈS FAIBLE TENEUR EN ANILINE ET SON PROCÉDÉ DE PRÉPARATION
Abstract:
(EN) Stable 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 0 to 45 % by weight based on the total weight of the solution, and wherein the stability of the solution is measured 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 stability of the solution is measured at a temperature of 60°C.
(FR) La présente invention concerne une solution aqueuse stable de leucoindigo comprenant une amine aromatique sous la forme d'aniline ou d'aniline et de N-méthylaniline, ledit leucoindigo se présentant sous la forme d'un sel de métal alcalin ; la concentration en ladite amine aromatique étant inférieure à 40 ppm déterminée selon la norme ISO 14362-1:2017(E) ; et la concentration en sel de leucoindigo étant située dans une plage de concentration allant de 0 à 45 % en poids par rapport au poids total de la solution, et la stabilité de la solution étant mesurée à une température de 23 °C ; ou la concentration en sel de leucoindigo étant située dans une plage de concentration allant de 45 à 65 % en poids par rapport au poids total de la solution, et la stabilité de la solution étant mesurée à une température de 60° C.
