Description
Дл получени нитрозо-производных а-нафтоЛсульфокислот обычно примен ютс в качестве исходных материалов сами а-нафтолсульфокисЛоты.For the preparation of nitroso derivatives of α-naphthoLsulfonic acids, α-naphtholsulfonic acids themselves are usually used as starting materials.
В предлагаемом способе исходным материалом дл получени ортонитрозоtx - Йафтолсульфокислот служат бисуль { )итные соединени .нитрозо-jS-нафтола или его замещенные путем обработки ий в водной среде сол ми гидроксиламина или веществ, отщепл ющих таковой .In the proposed method, bisulphonic compounds of nitroso-jS-naphthol or its substituted with hydroxylamine salts or substances that split it in water are used as the starting material for orthonitrosox-Yaftsulfonic acids.
Реакци может проводитьс в присутствии минеральной кислоты или без таковой при- нормальной или повышенной температуре.The reaction may be carried out in the presence of a mineral acid or without it at normal or elevated temperature.
Пример 1.-Раствор 27.7 ч. бисульфитного соединени нитрозо-р-нафтола, 7,6 ч. сол нокислого гидроксиламина и 10 ч. 20%-ной сол ной кислоты в 370 ч., воды нагревают до кипени . Жидкость при этом сильно буреет и приобретает красно-оранжевый цвет. После короткого нагревани раствору дают охладитьс . Уже в нагретой жидкости начинают выдел тьс желтые иглы соли нитрозоа - нафтолсульфокислоты. После полного охлаждени осадок отфильтровывают и слабо промывают водой. Выход-около 25,5 части.iExample 1. A solution of 27.7 parts of a nitrous-p-naphthol bisulfite compound, 7.6 parts of hydroxylamine hydrochloride and 10 parts of 20% hydrochloric acid in 370 parts, the water is heated to boiling. At the same time, the liquid turns brown and acquires a red-orange color. After brief heating, the solution is allowed to cool. Already in the heated liquid, yellow needles of the nitroso-naphtholsulfonic acid salt begin to secrete. After complete cooling, the precipitate is filtered off and washed slightly with water. Output is about 25.5 parts. I
Пример 2. - 240 объемных частей раствора бисульфйтньго соединени нитрозо - р - нафтола, полученного растворением нитрозо, выделенного из 22,5 ч. техническ. р-нафтола в 39 вес. част х раствора бисульфита натра (39° Вё) и воде, медленно рливают в смесь 300 об. ч. раствора гидроксиламиндисульфокислого натра, 150 ч. воды и 15 ч. сол ной кислоты (уд. в. 1,19).Example 2. 240 parts by volume of a solution of a nitrous-p-naphthol bisulfate compound prepared by dissolving nitroso, isolated from 22.5 hours of technical. p-naphthol in 39 wt. Parts of sodium bisulfite solution (39 ° Be) and water are slowly poured into a mixture of 300 vol. including sodium hydroxylamine disulfonic acid solution, 150 parts of water and 15 parts of hydrochloric acid (sp. c. 1.19).
Расгвор гидроксипаминдисульфокислого натра готовилс насыщением сернистым газом смеси 21 ч. нитрита натра и 84 ч. раствора бисульфита натра (39° Вё) и льда.A sodium hydroxypamine disulfonate solution was prepared by saturating a mixture of 21 parts of sodium nitrite and 84 parts of sodium bisulfite solution (39 ° Ve) and ice with sulfur dioxide.
Реакци ведетс в аппарате, снабженном мещалкой и обратным холодильНИКОМ .The reaction is carried out in an apparatus equipped with a broom and reflux cooler.
Дальнейща переработка как в примере первом. ;Выход 34 части.Further processing as in the first example. ; Exit 34 parts.
Пример 3.-Раствор 9,4 частей бариевой соли бисульфитного соединени нитрозо, 2,6 нафтолсульфокислоты, 3 части сол нокислого гидроксиламина, 4 части 20%-ной сол ной кислоты в 140 ч. воды нагревают до кипени . Остальна обработка аналогична примеру первому. Выход соли нитрозо - а нафтолдисульфокислоты-6 ,9 частей.Example 3. A solution of 9.4 parts of the barium salt of the nitroso bisulfite compound, 2.6 naphtholsulfonic acids, 3 parts hydroxylamine hydrochloride, 4 parts of 20% hydrochloric acid in 140 parts of water are heated to boiling. The rest of the processing is similar to the first example. Yield of nitroso salt - and naphthol disulfonic acid - 6, 9 parts.
