Description

Предметом изобретени   вл етс  способ получени  ампиоаиттптпрцпа , употребл емого в медицинской нра1хтпке, из интрозоантинирина.The subject of the invention is a method for producing an ampioaittprcpa used in medical technology from introzoanthinirin.

Способ получ ептг  а{миноаптппнрина путем восстановлени  иитрозоаитниирпна пзвестеп. Однако применение нзвестных дл  DTOII цели i5ocстановнтелей , например, раствора сульфит110-бисульф}1тноп смеси, приводит к нолучепню сильно загр зненного препарата, а очистка сопр жена со значительной потерей его и усложпонпем способа.The way to get aptonga {minoaptppnrin by restoring itoprostnirpna pzvestep. However, the use of i5-known reducing agents for DTOII, for example, sulfite 110-bisulfide} 1t mixture, leads to the accumulation of a highly contaminated preparation, and cleaning results in a significant loss of it and complication of the method.

Отличительной особенностью предлагаемого способа  вл етс  то, что в Kat ecTiio восстановител  дл  неревода пнтрозоаптипнрнна в амнноантннирнн применен /двусерннстый водород.A distinctive feature of the proposed method is that in Kat ecTiio of a reducing agent, non-hydrogenated bi-hydrogen is used for not conducting pntozaprippnrnna in amnnoantnnirnn.

Это позвол ет повыснть выход готового 1гнрампдопа п в несколько раз сокращает врем  нротекани  реакции. Способ получени  а1миноантнпнрина нз питрозоаптпппрпна заключаетс  в следующем. К суспензни литрозоантииирнна в воде пебольшнмн порци мн прибавл ют сол ную кислоту п раствор двусернистого натри  с такнм расчетом, чтобы среда реакционной смеси была на конго слабокпсло, а температура ее не выше 25°. Образующпйс  при этих услови х двусернистый водород тотчас же вступает во взапмодействне с нптрозоантнннрнном, в результате чего образуетс  аминоаптнпирин п при этом освобо;кдаетс  сера. Реакци  восстр повле п1  протекает быстро п заканчиваетс  в течение 2 - 3 час.This allows an increase in the yield of ready-made n-rampdop n, which shortens the reaction time several times. The method for producing the aminoanthnnrin nz pitrozoaptpprppna is as follows. Hydrochloric acid and a solution of sodium sulphuritic acid are added to a suspension of litrosoantiiirnn in water in a large portion of a lot of people, with the expectation that the medium of the reaction mixture is weak and the temperature is not higher than 25 °. Under these conditions, the formation of hydrogen disintegrated hydrogen immediately takes place in conjunction with the development of nano-sulfur, resulting in the formation of amino-optinyl pyrhenium and the release of sulfur. The reaction is followed by a reaction that proceeds rapidly and ends within 2 to 3 hours.

Полученный сол нокислый раствор ампноантппирина в зависимости от необходимости иснользуют или дл  выделени  чистого аминоантнпирина или дл  получени  нирампдона. Получение ампноантппнрппа осуществл ют нутем отфильтровывани  серы п .жстрагировапи  пол5ченного раствора подход щими органическими растворнтел мн после его нредварительного иодщелачиванп  в нрнсутствшг фенолфталеина. С целью получени  пирамидона, сол покисльп раствор амнноаптпннрнна вместе с выпавшей серой пускают на метнл1трован11е.The resulting hydrochloric acid solution of ampnoanthppirin, depending on the need, is used either for the isolation of pure aminoanthiprine or for the preparation of nirampdon. The preparation of the ampnoantine solution is carried out by filtering the sulfur of the organic salt solution with suitable organic solvent after it has been preliminarily oxidized in the presence of phenolphthalein. In order to obtain pyramidone, the salt of the pyramid solution is amnnoaptnnnnna together with the precipitated sulfur is allowed to go on methylented.
