Description

При обработке алпзарнн-хинолина-3 бисульфитом натри  реакци  образовани  бисульфитного соединени , примен емого :при печати на ткан х, идет очень медленно и при 45° заканчиваетс  за 24 часа. Выделение полученного продукта происходит в мелких кристаллах и его фильтрование и очистка от примесей вызывает значитсотьные технологические трудности.When treating alparn-quinoline-3 with sodium bisulfite, the reaction to form the bisulfite compound used: when printing on fabrics, it goes very slowly and at 45 ° it ends in 24 hours. Isolation of the obtained product occurs in small crystals and its filtration and purification from impurities causes, therefore, hundreds of technological difficulties.

По описываемому способу эту реакцию провод т В тфисутствии небольшого количества пиридина, что сокращает длительность реакции до 3-5 час. Образующеес  бисульфитное соединение ализар-нн-хинолина-3 выпадает при Охлаждении раствора в форме крупных кристаллов, фильтрование и очистка которых не вызывает никаких осложтшний.According to the described method, this reaction is carried out in the absence of a small amount of pyridine, which shortens the reaction time to 3-5 hours. The resulting bisulfite compound alizar-n-quinoline-3 precipitates upon cooling of the solution in the form of large crystals, the filtration and purification of which does not cause any complications.

Пример. 143 г пасты, содержащей 40 г ализарин-хинолина-З, 160 г 40%-ного раствора бисульфита натри  и 2,5 мл пиридина, размешивают до получени  однородной массы,которую нагревают до 45° и выдерживают при этой теМИератзфе при перемешивании 3-5 часов, до исчезновени  в реакционной массе ненрореагировавшего ализарин-хинолина-З. По окончании реакции массу охлаждают до 25, перемешивают 1 час п фильтруют через фильтр из джутоваг ткани. Отжатый осадок снимают с фильтра, размешивают с 250 мл раствора , содержащего 12% NaCl и 1 % NaHSOs, и снова фильтруют через хлор:випнло1 ую ткань, после чего сушат.Example. 143 g of a paste containing 40 g of alizarin-quinoline-3, 160 g of a 40% aqueous solution of sodium bisulfite and 2.5 ml of pyridine, are stirred until a homogeneous mass is obtained, which is heated to 45 ° and maintained at this temperature with stirring 3-5 hours, until disappearing in the reaction mass of unreacted alizarin-quinoline-3. At the end of the reaction, the mass is cooled to 25, stirred for 1 hour and filtered through a filter of jute cloth. The pressed precipitate is removed from the filter, stirred with 250 ml of a solution containing 12% NaCl and 1% NaHSOs, and again filtered through chlorine: a cloth, and then dried.

Отфильтрованный осадок бнсулт)фитного соединени  ализарин-хинслина-3 представл ет собой крупные блест пи- е кристаллы. Выход 65 сухого красител .The filtered precipitate of the alsarin-Hinslin-3 phytic compound is a large gloss crystal. Exit 65 dry dye.

Предмет изобретени Subject invention

Способ получени  бисульфитного соединени  ализарин-хинолина-З нутем обработки ализарин-хинолина-З раствором бисульфита натри , о тличаюшийс  тем, что, с целью сокращени  времени реакции и получени  продзктов в форме крупных кристаллов, обработку провод т в присутствии пиридина Б количестве не более 10% отвеса ализарип-хинолина-3 , .после чего выдел ют полученное бисульфитное соединение изоестиым cnocci6oM.The method of producing the alisarin-quinoline-3 bisulfite compound by treating the alizarin-quinoline-3 solution with sodium bisulfite solution, which is that, in order to shorten the reaction time and to obtain products in the form of large crystals, the treatment is carried out in the presence of pyridine B in an amount of not more than 10 % plummet alizarip-quinoline-3, after which the resulting bisulfite compound is isolated with cnocci6oM.
