Description
3 линсульфокислоты, отличающийс тем, что натриевую соль Ы- -хлор-р - оксипропилили N-p,Y - эпоксипропил - 1 - амино-4(5- или 6)-нафталипсульфокислоты подвергают щелочному гидролизу при температуре 55-60°С5 и рН среды 10-12. 2. Способ по п. 1, отличающийс тем, 4 что гидролиз провод т в присутствии едкого натра. Источник информации, прин тый во внимание при экспертизе: К. Бюлер и Д. Пирсон, Органические синтезы, ч. I, М., изд. Мир. 1973, стр. 202- 205, .3 linsulfonic acids, characterized in that the sodium salt of L- -chloro-p-hydroxypropyl or Np, Y-epoxypropyl-1-amino-4 (5- or 6) naphthalipsulphonic acid is subjected to alkaline hydrolysis at a temperature of 55-60 ° C5 and a pH of 10 -12. 2. A method according to claim 1, characterized in that 4 that the hydrolysis is carried out in the presence of caustic soda. The source of information taken into account in the examination: K. Buhler and D. Pearson, Organic Synthesis, Part I, M., ed. World. 1973, pp. 202-205,.
