Description
В основном патенте Ns 4550 описан способ выделени ароматических амидооксисоединений из растворов щелочных солей их, основанный на прибавлении к этим растворам солей аммони (нашатыр , сернокислого, углекислого, уксуснокислого аммони и т. п.), при чем особенно хорошие результаты получаютс при применении этого способа дл осаждени амидофенолов после получени их щелочных солей восстановлением-нитрозофенолов сернистыми щелочами.The main patent Ns 4550 describes a method for separating aromatic amido-oxo compounds from their alkaline salts solutions, based on adding ammonium salts to these solutions (ammonia, ammonium sulphate, carbonate, ammonium acetate, etc.), and the best results are obtained using this method to precipitate amidophenols after their alkaline salts are obtained by reducing the nitrosophenols with sulfurous alkalis.
В дальнейшем автором найдено, что столь же хорошие результаты дает указанный способ в применении к продуктам щелочного плавлени амидосульфокислот ароматического р да, а также к продуктам щелочного восстановлени (например сернистым натрием) индофенолов и инданилинов , а такжеч вообще во всех случа х, когда продуктом реакции вл етс щелочной раствор какого-либо амидооксисоединёни .Further, the author found that this method gives equally good results when applied to the alkaline melting products of the amidosulfonic acid of the aromatic series, as well as to the alkaline reduction products (for example, sodium sulfide) of indophenols and indanilines, as well as in general in all cases when the reaction product is an alkaline solution of any amido-oxo compound.
Пример 1.-Плав, полученный сплавлением 150 ч. диметиланилин-1га-сульфокислого натри с едким кали раствор ют в 800 ч. воды и прибавл ют к еще гор чему раствору 300 ч. сернокислого аммони , растворенного в 600 ч. воды. Выделившийс в виде масл нистого сло диметил-да-амидофенол отдел ют от водного раствора солей и подвергают обычной очистке.Example 1. The melt obtained by fusing 150 parts of sodium dimethylaniline-1ha-sulfonic acid with caustic potassium is dissolved in 800 parts of water and 300 parts of ammonium sulfate dissolved in 600 parts of water are added to a still hot solution. The dimethyl-amidophenol released in the form of an oily layer is separated from the aqueous salt solution and subjected to ordinary purification.
Пример 2.-К продукту сплавлени с 200 ч. едкого натра 100 ч. 2-нафтиламин-8-сульфокислоты , по растворении его в воде, прибав. ют раствор 350 ч. уксуснокислого аммони в 700 ч. воды. Выделившийс осадок 2-амидо-8-нафтола отдел ют и очищают обычными способами.Example 2.-To the product of fusion with 200 parts of caustic soda 100 parts of 2-naphthylamine-8-sulfonic acid, by dissolving it in water, adding. a solution of 350 parts of ammonium acetate in 700 parts of water. The precipitated 2-amido-8-naphthol is separated and purified by conventional methods.
Пример 3.-К реакционной смеси, полученной при восстановлении N-ортотолил- -хинонимида сернистым натрием одним из общеупотребительных способов прибавл ют раствор 1 ч. углекислого аммони в 2 ч, воды до полного выпадени продукта реакции. Выпавший в осадок jj-оксифенил-о-толил амина очищают обычными способами или перерабатывают пр мо на сернистый краситель.Example 3.-To a reaction mixture obtained by reducing N-orthotolyl-α-quinone imide with sodium sulphide, one of the commonly used methods was added a solution of 1 part of ammonium carbonate in 2 hours, water until complete loss of the reaction product. The precipitated jj-hydroxyphenyl-o-tolyl amine is purified by conventional methods or processed directly into a sulfur dye.
Предмет патента.The subject of the patent.
Прием выполнени означенного в патенте № 4550 способа выделени амидооксисоединекий ароматического р да из раствора их щелочных солей, отличающийс тем, что сол ми аммони в сухом виде или в виде растворов обрабатывают продукты сплавлени со щелочами сульфокислот ароматических аминов, а равно и продукты щелочного восстановлени индофенолов или содержащих кислород индаминов.Acceptance of the method for separating an amido-oxy compound of the aromatic series from the solution of their alkaline salts, noted in patent No. 4550, characterized in that ammonium salts in dry form or in the form of solutions are processed by fusion with the alkali sulfonic acids of aromatic amines, as well as the products of alkaline reduction of indophenols or oxygen-containing indins.
