Description
Лмино-3-хлор-4-оксибензол-1-арсинова кислота образуетс , как промежуточный продукт, при получении Н-ациламино-3-хлор-4-оксибензол -1 - арсиновой кислоты (см. советский патент № 12152). Она, однако, изолируетс из восстанавливаемой смеси в очень незначительном количестве и в нечистой форме. Предлагаемый способ получени названной кислоты в большом количестве и чистом виде, заключаетс в обработке ациловых ее соединений, указанных в упом нутой за вке, омыл ющими веществами . До сих пор известна , не содержаща хлора З-амино-4-оксибензол-1-арсинова кислота неприменима с терапевтической целью, вследствие своей незначительной стойкости: она даже в чистом кристаллическом виде окрашиваетс в темный цвет уже через короткое врем (см, Zentralblatt fur Haut u. Geschlechtskrank heiten Bd.Lmino-3-chloro-4-hydroxybenzene-1-arsic acid is formed, as an intermediate product, upon receipt of H-acylamino-3-chloro-4-hydroxybenzene -1 - arsic acid (see Soviet Patent No. 12152). It is, however, isolated from the mixture to be recovered in very small amounts and in impure form. The proposed method for the preparation of the abovementioned acid in large quantities and in pure form consists in treating the acyl compounds thereof, mentioned in the said application, with scrubbing agents. The chlorine-free 3-amino-4-hydroxybenzene-1-arsic acid is still not known for therapeutic purposes due to its low persistence: even in its pure crystalline form, it becomes dark in a short time (see, Zentralblatt fur Haut u. Geschlechtskrank heiten Bd.
. 17, Heft 11/12 стр. 689). Лмино-3хлор - 4- оксибензол- 1- арсинова кислота, наход ща применение в терапевтической практике, отличаетс , напротив того, значительной стойкостью-даже при продолжительном действии резкого света она остаетс вполне бесцветною и неразложенною.. 17, Heft 11/12 p. 689). Lmino-3-chloro-4-hydroxybenzene-1-arsic acid, which is used in therapeutic practice, is, on the contrary, very persistent — even with prolonged exposure to strong light, it remains completely colorless and indecomposable.
Пример. Хлор-амидо-фенол-арсинова кислота . 720 г З-хлор-4-окиси-ацетил - амидобензол - арсиновой кислоты размешиваютс с 1000 t едкого натра 38° Вё и 1000 г воды в течение 5 часов на вод ной бане. Полученный раствор разбавл етс водою до объема в 3500 кг/б, см, охлаждаетс до 30° и фильтруетс . При прибавлении сол ной кислоты до начинающейс слабо-кислой реакции на метил-оранж, постепенно выкристаллизовываетс образовавша с кислота в виде плоских белых иголок. После отсасывани , промывают водой до нейтральной реакции.. Кислота кристаллизуетс из гор чей воды в виде мелких бе.Example. Chloro-amido-phenol-arsine acid. 720 g of 3-chloro-4-oxide-acetyl-amidobenzene-arsine acid are mixed with 1000 t of caustic soda 38 ° Be and 1000 g of water for 5 hours in a water bath. The resulting solution is diluted with water to a volume of 3500 kg / b, cm, cooled to 30 ° and filtered. Upon the addition of hydrochloric acid to the beginning of a weakly acidic reaction to methyl orange, the formed acid gradually crystallizes out as flat white needles. After suctioning, it is washed with water until neutral. The acid crystallizes from the hot water in the form of small be.
лых иголочек, плав щихс при 257- она довольно трудно раствор етс в плодной воде, нерастворима в эфире, бензоле и лигроине, но легко растворима в разбавленных кислотах, едких щелочах и растворе соды, довольно легко в метиловом спирте. Раствор диазосоединени интенсивно-желтого цвета и в комбинации с резорцином дает желтокрасное крас щее вещество.needles, melting at 257, it is rather difficult to dissolve in fetal water, insoluble in ether, benzene, and ligroin, but easily soluble in dilute acids, caustic alkalis, and soda solution, rather easily in methyl alcohol. The diazocompound solution is an intense yellow color and, in combination with resorcinol, gives a yellow-red dye.
