Abstract

Procedure for obtaining stilbene derivatives, of general formula **(See formula)** where X and Y, independent of each other, mean in each case a phenylemino residue, which can be substituted, and both a residue of the formula **(See formula)** how much formula **(See formula)** T and Z each signify both a residue of formula (II) and (III), R is chosen from hydrogen and low molecular weight alkyl, which may be substituted by hydroxy, alkoxy, cyano, aminocarbonyl, phenyl, phenoxy and cresoxy, R1 is chosen from hydrogen and a low molecular weight alkyl moiety, R2 means hydroxy, cyano, -CO-CmH2m + 1, (see formula) as well as -COOR7, R3 and R4, independent of each other, mean in each case both a low molecular weight alkyl moiety, and hydroxyalkyl as R3 and R4, together with the nitrogen atom, form a saturated heterocyclic moiety, R5 and R6, independent of each other, are chosen from a hydrogen atom, a low molecular weight alkyl moiety and a hydroxyalkyl group, since R5 and R6, together with the nitro-hay atom, form a saturated heterocyclic moiety, R7 stands for a low molecular weight alkyl moiety which may be substituted by hydroxy, alkoxy, phenoxy, cresoxy as well as phenyl, Me represents an equivalent of a metal chosen from an alkali and alkaline earth metal as well as an ammonium group. Anion is a colorless anion and m is a number from 1 to 3, n is chosen from 1 to 2 and p is a number from 2 to 6, with all residues being able **(See formula)** in the substituents T, X, Y and Z, they are the same as well as different from each other and all the residues R3 to R6, likewise, the same and also different from each other, the molecule presenting only two sulfonic radicals linked to the stilbene moiety, characterized in that in arbitrary sequence, both 2 moles of a cyanuric halide are reacted with a) 1 mole of 4,4'-diaminoestilben-2,2'-disulfonic acid, which may be in the form of a salt, b) 0 to 2 moles of an aminobenzene, which may be substituted and c) 2 to 4 moles of an amine of formula **(See formula)** both in the single state and in the form of a mixture of amines of formula (IV); the amines mentioned under b) and c) totaling 4 moles, the reaction product being reacted with a compound chosen from an acid and a quaternizing agent; as 1 mol of a cyanuric halide is reacted with a) 1 mol of acid chosen from 4-amino-4'-nitro- acid and 4-amino-4'-acylaminoestilben-2,2'-disulfonic acid, which may be in the form of a salt, b) 0 to 1 mol of an aminobenzene, which may be substituted, c) 1 to 2 mol of an amine of formula (IV) both in the single state and in the form of a mixture of amines of formula (IV), bringing the amines mentioned under b) and c) to a total of 2 moles, then the nitro group is reduced, just as the acylamino group is hydrolyzed and the amino group is reacted with 1 mole of a cyanuric halide and the compound Dihalogenotriazinioic acid is reacted in arbitrary sequence with d) 0 to 1 mol of an aminobenzene, which may be substituted, and e) 1 to 2 mol of an amine of formula (IV), both in the single state and in the form of a mixture of amines of formula (IV), the amines mentioned under d) and e) amounting to a total of 2 moles, being able to react the product reaction with a compound chosen from an acid and a quaternizing agent.
