Abstract
Procedure for obtaining direct stylebenzanic colorants. Consists of the alkaline condensation, aqueous, of a mixture of a lithium salt of 5-nitro-o-toluenosulphonic acid and a sodium salt of the acid 4,4 '' - dinitro-2,2 '' - estilbendisulfonico, in presence o absence of a reducing agent. The proportion between alcali and the reactants is selected so that the product contains lithium and sodium atoms in the 1: 2 relationship, at least. Condensation can be carried out with a single reactant or different mixtures. The reduction can be a subsequent process. These colors are used to dye paper.
