Description

Предлагаемое изобретение относитс  к способам получени  парааминофенилстибиновой кислоты.The present invention relates to methods for the preparation of para-aminophenylstibic acid.

Известно, что указанна  кислота и ее соли обладают весьма незначительной стойкостью (Шмидт, Ann., 429, стр. 146, 147). Хот  удаетс  получить растворимые щелочные соли названной стибиновой кислоты , все же они имеют тенденцию переходить , даже при сохранении в закрытых ампулах, в нерастворимую форму или в такое состо ние, при котором они хот  и раствор ютс  в воде, но этот раствор , скоро мутнеет.It is known that this acid and its salts have very little resistance (Schmidt, Ann., 429, pp. 146, 147). Although it is possible to obtain soluble alkaline salts of the said stibic acid, they still tend to transfer, even when stored in closed ampoules, to an insoluble form or to a state in which they dissolve in water, but this solution soon becomes cloudy.

Ныне автором найдено, что вторичные амины, как, например, диэтиламин, пиперазин и др., образуют с парааминофенилстибиновой кислотой свободные от вышеназванного недостатка соли, которые дают не скоро мутнеющие водные растворы , остающиес  даже при продолжительном хранении чистыми, А. И,Now the author has found that secondary amines, such as, for example, diethylamine, piperazine, etc., form with para-aminophenylstibic acid free salts, which do not soon become turbid, that remain even after long-term storage with pure, A. And,

Пример, Полученную известным образом из 150 г параацетиламинофенилстибиновой кислоты при помощи омылени  парааминофенилстибиновую кислоту встр хивают во влажном состо нии с двунормальным водным раствором диэтиламина, который прибавл ют до тех пор и в таком количестве, пока не произойдет полного растворени . Полученный раствор фильтруют, осаждают вливанием ацетона, а выпавший продукт сушат в эксикаторе. Получают слабо окрашенный порошок, который и после долгого хранени  раствор етс  в воде и образует раствор, стойкий в течение некоторого времени.Example: Obtained in a known manner from 150 g of para-acetylaminophenylstibic acid by para-aminophenylstibic acid saponification is shaken in a wet state with a biodormal aqueous solution of diethylamine, which is added until such time as it is completely dissolved. The resulting solution is filtered, precipitated by pouring acetone, and the precipitated product is dried in a desiccator. A slightly colored powder is obtained, which, after long storage, dissolves in water and forms a solution that persists for some time.
