Description

Стабилизаци  в активной форме диазосоединений обычно достигаетс  получением сульфокислых солей или с помощью минеральных солей т желых или щелочных металлов. Кроме того целым р дом патентов предусмотрена стабилизаци  диазосоединений в виде фторосульфонатов, фторборатов и целого р да других содержащих фтор соединений.Stabilization in the active form of the diazo compounds is usually achieved by obtaining sulphate salts or by using mineral salts of heavy or alkali metals. In addition, a number of patents provide for the stabilization of diazo compounds in the form of fluorosulfonates, fluoroborates, and a whole series of other fluorine-containing compounds.

Автором насто щего изобретени  найдено, что стабилизировать диазосоединени  можно с помощью любых не содержащих фтора гетерополикислот или их солей. В качестве таких гетерополикислот можно указать на фосфоровольфрамовуюThe author of the present invention has found that it is possible to stabilize diazo compounds with the help of any fluorine-free heteropoly acids or their salts. As such heteropolyacids, you can specify the phosphorus acid

Вместо готовых названных кислот дл  реакции образовани  стабилизированного диазосоединени  можно употребл ть растворы их, специальноInstead of ready-made named acids, their solutions can be used for the formation of a stabilized diazo compound, specifically

приготовленные из соответствующих компонентов.prepared from the relevant components.

Комплексные диазосоединени  из гетерополикислот обладают малой растворимостью в воде, легко фильтруютс  и промываютс . Устойчивость этих солей весьма велика, они не взрывоопасны, сравнительно трудно воспламен ютс  и кроме того выдерживают длительное кип чение в кислой или нейтральной среде без вс кого разложени .Complex diazo compounds from heteropolyacids have little solubility in water, are easily filtered and washed. The stability of these salts is very high, they are not explosive, they are relatively difficult to ignite and, moreover, they withstand long-term boiling in an acidic or neutral medium without decomposition.

Комплексные соли диазосоединений легко сочетаютс  с азокомпонентами как на волокне, так и в растворах.Complex salts of diazo compounds are easily combined with the azocomponents on the fiber and in solution.

Пример 1. К раствору сол нокислого диазо-п-нитро-анилина, полученного обычным образом из 1,45 г п-нитро-анилина, 3 мл сол ной кис ,лоты (уд. в 1,19), 15 мл воды и 7 г 20/Q-ro раствора нитрита при О-8° приливают раствор 9,2 г кремневольфрамовой кислоты, растворенной, в 75 мл воды. Растворы комплексной кислоты приливают до полного выделени  диазосоединени  в осадок. Получаетс  комплексна  соль диазосоединени  почти белого цвета, которую отфильтровывают, промывают и высушивают .Example 1. To a solution of diazo-p-nitroaniline hydrochloride, prepared in the usual way from 1.45 g of p-nitroaniline, 3 ml of hydrochloric acid, lots (beats in 1.19), 15 ml of water and 7 g 20 / Q-ro solution of nitrite at O-8 ° poured a solution of 9.2 g of silicotungstic acid, dissolved in 75 ml of water. Solutions of the complex acid are poured in until the diazo compound is completely precipitated. The diazocompound complex salt of almost white color is obtained, which is filtered, washed and dried.
