Osintseva // Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). - 2002. - Vol. 38, № 3. - P385-389 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: 4-[4-Bis(2-carboxyethyl)aminophenylazo]benzenesulfonic acid and 4-[2-bis(2-carboxyethyl)amino-4,5-dimethylphenylazo]benzenesulfonic acid were synthesized for the first time by azo coupling of diazosulfanilic acid with N,N-bis(2-carboxyethyl)aniline and N,N-bis(2-carboxyethyl)-3,4-xylidine, respectively. The acid ionization constants of the products were determined, their electron absorption spectra were measured, and schemes of acid-base equilibria in aqueous solution were proposed \\\\Expert2\\nbo\\Russian Journal of Organic Chemistry\\2002, 38 (3), 385.pdf |
