The synthesis and properties of triazine-stilbene fluorescent brighteners containing the phenolic antioxidant

Disodium 4,4'-bis(1,3,5-triazin-6-yl)diaminostilbene-2,2'-disulfonate derivatives (11a-h) which were substituted with 4-amino2,6-di-tert-butylphenol (3) or 4-(2-amino-ethyl)-2,6-di-tert-butylphenol (6) as an antioxidant on triazine moiety were prepared. The obtained compounds were characterized by the analysis of the proton NMR spectrum and confirmed by UV spectrum. The physical properties of the new compounds (11a-h) were performed by fastness test and whiteness measurement, compared with those of C186 and C190. (C) 2004 Elsevier Ltd.
