Description
где Б aHTpaxHHOHOBOjM дре один X-Н, а другойХ- бепзоиламиногруппа или где оба X - Н, который лишен указанного недостатка.where B aHTpaxHHOHOBOjM Dre one X-H, and the other H-bepsoylaminogroup or where both X - H, which is deprived of this disadvantage.
По предлагаемому способу указанные красители получают конденсацией мела мина с 1-хлорантрахиноном или его бензоиламинопроизводными при наЕревании в присутствии галоидных солей меди пли смеси меди и йода в качестве катализаторов. Процесс конденсации ведут в инертном растворителе, либо путем запекани .According to the proposed method, these dyes are obtained by condensation of chalk mine with 1-chloroanthraquinone or its benzoylamino derivatives when heated in the presence of copper halide salts or mixtures of copper and iodine as catalysts. The condensation process is carried out in an inert solvent, or by baking.
Выход красителей по предлагаемому способу не уст пает выходу их из хлористого цианура и аминопроизводных антрахинона.The yield of dyes according to the proposed method does not satisfy their exit from cyanure chloride and amino derivatives of anthraquinone.
Пример 1. 1,68 г измельченного меламина, 9,9 г 1-хлорантрахинона , 6,53 г безводной соды, 0,4 г йодистой меди и 80 м.л нитробензола нагревают в течение час. при температуре кипени последнего. После этого реакционную массу охлаждают до 120-130° и фильтруют. Осадок промывают на фильтре нк1тробензолом, а затем освобождают от последнего путем отгонки с вод ным паром, после чего его кип т т в З о-ной сол ной, кислоте, отфильтровывают, промывают гор чей водой и сушат.Example 1. 1.68 g of crushed melamine, 9.9 g of 1-chloroanthraquinone, 6.53 g of anhydrous soda, 0.4 g of copper iodide and 80 ml of nitrobenzene are heated for an hour. at the boiling point of the latter. After that, the reaction mass is cooled to 120-130 ° and filtered. The precipitate is washed on the filter with n1trobenzene, and then freed from the latter by distillation with steam, after which it is boiled in hydrochloric acid, filtered off, washed with hot water and dried.
