Description

Известный закрепитель ДЦУ дл  пр мых (салпциловых) и протравных красителей  вл етс  продуктом конденсации дициандиамида с формальдегидом, обработанным зксусной кислотой.The known fixer DCU for direct (salpcylic) and mordant dyes is a condensation product of dicyandiamide with formaldehyde, treated with acetic acid.

Описываемый способ относитс  к получению закрепител  дл  пр мых красителей путем конденсации дициандиамида с формальдегидом .The described method relates to the preparation of a fixative for direct dyes by condensation of dicyandiamide with formaldehyde.

Отличительна  особенность этого способа состоит в том,- что вместо уксусной кислоты, конденсацию ведут в присутствии хлористоводородных солей алифатических третичных аминов, например триэтаноламина .A distinctive feature of this method is that instead of acetic acid, condensation is carried out in the presence of hydrochloric salts of aliphatic tertiary amines, for example, triethanolamine.

Этот способ расшир ет возмол ности синтеза закрепител ,, подобного известпому закрепителю ДЦУ.This method extends the possibilities of the synthesis of a fixer, similar to the known fixer DCU.

В закрытый дерев нный чан, снабженный змеевиком и мешалкой, ввод т 33,6 вес. ч. дицианамида и 30 вес. ч. формалина. Сюда же ввод т хлористоводородную соль триэтаиоламина, ириготовленную нейтрализацией по лакмусу (до слабокислой реакции), 4,6-5,8 вес. ч. триэтаноламина и 4-5 вес. ч. сол ной кислоты с содержанием НС в количестве 28%. Смесь постепенно нагревают до температуры 80-90 в течение 30-60 мин до полной однородности, после чего охлаждают до температуры 60-70 и при размешивании постепенно добавл ют 50 вес. ч. 23%-ной сол ной кислоты, довод т температуру до 80-90° и выдерживают при этой температуре до растворени  пробы в воде.33.6 wt. Are added to a closed wooden tank equipped with a coil and a stirrer. including dicyanamide and 30 wt. including formalin. Trietheiolamine hydrochloride salt, iriganized by neutralization by litmus (to a weakly acid reaction), 4.6–5.8 wt. including triethanolamine and 4-5 wt. including hydrochloric acid with an HC content of 28%. The mixture is gradually heated to a temperature of 80-90 for 30-60 minutes until complete homogeneity, then cooled to a temperature of 60-70, and while stirring, 50 weight is gradually added. including 23% hydrochloric acid, the temperature is adjusted to 80-90 ° C and maintained at this temperature until the sample is dissolved in water.
