Description
Предметом насто щего изобретени вл етс способ выделени ксантина и гуанина из свекловичной патоки.The subject of the present invention is a method for isolating xanthine and guanine from beet syrup.
10 литров свекловичной патоки разбавл ют 200 литрами воды, после чего добавл ют раствор основной уксусноСБинцовой соли. Полученный осадок основных свинцовых солей отфильтровывают . Получаетс 320 литров фильтрата. После этого основные свинцовые соли промывают сначала 65 литрами холодной воды, а затем таким же количеством гор чей .10 liters of beet molasses is diluted with 200 liters of water, after which a solution of basic acetic acid salt is added. The precipitate of the main lead salts is filtered off. 320 liters of filtrate are obtained. After that, the basic lead salts are washed first with 65 liters of cold water and then with the same amount of hot water.
Фильтрат в количестве 320 литров соедин ют с промывными водами и получают 450 литров раствора.A filtrate of 320 liters is combined with the washings and 450 liters of solution are obtained.
К раствору при помешивании прибавл ют тонкой струей 25 литров 20 /о-го раствора серной кислоты дл осаждени свинца. После этого нейтральный раствор может бродить и может быть использован дл целей винокурени .While stirring, 25 liters of a 20 / o sulfuric acid solution are added to the solution with a thin stream to precipitate lead. After that, a neutral solution can ferment and can be used for distillation purposes.
Основные уксусно-кислые соли свинца обрабатывают 40 литрами Т /о-го раствора соды при нагревании. Полученный раствор отфильтровывают от углекислого свинца, промывают осадок гор чей водой и получают 140 литров фильтрата и 7 кг углекислого свинца. Углекислый свинец с целью регенерации раствор ют в уксусной кислоте и по добавке необходимого количества глета снова пре (94)The main acetic acid salts of lead are treated with 40 liters of T / o solution of soda when heated. The resulting solution is filtered off from carbon dioxide, the precipitate is washed with hot water and 140 liters of filtrate and 7 kg of carbon dioxide are obtained. For the purpose of regeneration, carbon dioxide of lead is dissolved in acetic acid and, after addition of the required amount of gluten, again (94)
вращают его в основной уксусно-кислыи свинец, пригодный дл осаждени мелассы .rotate it in basic acetic acid lead suitable for precipitation of molasses.
Фильтрат от углекислого свинца нейтрализуют 10%-ым раствором серной кислоты, на что требуетс 6 литров кислоты; при этом выпадает осадок, который отфильтровывают, промывают при кип чении и раствор ют при нагревании в 20 литрах воды. Полученный раствор отфильтровывают от нерастворившейс части; фильтрат после охлаждени отдел етс от выпавшего осадка. Полученные оба осадка, содержащие ксантин и гуанин раствор ют при нагревании в Т /о-ом растворе соды, полученный раствор нейтрализуют серной кислотой, затем добавл ют еще серной кислоты и выпавший осадок ксантина- отдел ют. Фильтрат нейтрализуют едким натром; при этом из него выпадает гуанин.The filtrate from lead carbonate is neutralized with a 10% solution of sulfuric acid, which requires 6 liters of acid; a precipitate is formed, which is filtered off, washed at the boil and dissolved by heating in 20 liters of water. The resulting solution is filtered from the undissolved portion; the filtrate after cooling is separated from the precipitated precipitate. The resulting precipitates, containing xanthine and guanine, are dissolved by heating in a T / o soda solution, the resulting solution is neutralized with sulfuric acid, then more sulfuric acid is added and the precipitated xanthine is separated. The filtrate is neutralized with caustic soda; at the same time from it falls guanine.
Предмет изобретени .The subject matter of the invention.
1. Способ выделени ксантина и гуанина из свекловичной патоки, отличающийс тем, что сначала на разбавленную водой патоку действуют уксусно-кислым свинцом дл образовани осадка, который после промывки обрабатывают раствором соды дл получени углекислого свинца и раствора, на который затем действуют разбавленной серной кислотой,. с целью выделени осадк который, после промывани rojэ eй водой, раствор ют в растворе соды, юлученный раствор нейгрализ ют и BHOBI обрабатывают разбавленнойсерной кислотой дл образовани осадка, из которого при помощи едкой щелочи извлекают ксантин, осаждаемый обычным путем из щелочного раствора, а из сернокислого раствора при нейтрализации осаждают гуанин. 2. В означенном в п. 1 способа превращение осадка карбоната свинца в основной /ацетат-свинца растворением карбоната в уксуснойкислоте и последующей обработкой раствора глетом. 3. В означен.чом в п. Гспособе применение получейного при обработке патоки основным ацетатом свинца раствора, после осаждени из него свинца при действии серной кислоты и при последующей нейтрализации дл получени спирта путем брожени .1. A method of isolating xanthine and guanine from beet molasses, characterized in that at first the lead water is diluted with water with acetic acid lead to form a precipitate, which after washing is treated with soda solution to obtain carbon dioxide lead and a solution, which is then affected with dilute sulfuric acid, . in order to precipitate a precipitate which, after being washed with water, dissolved in soda solution, the irradiated solution is neutralized and BHOBI is treated with dilute sulfuric acid to form a precipitate from which xanthine precipitated out of alkaline solution is extracted from caustic alkali and guanine is precipitated during neutralization solution. 2. In the method mentioned in paragraph 1 of the transformation of the precipitate of lead carbonate into basic / acetate-lead by dissolving the carbonate in acetic acid and subsequent treatment of the solution with lithium. 3. In the meaning of p. Gosposche, the use of the solution obtained during treating molasses with basic lead acetate, after lead precipitating from it under the action of sulfuric acid and during subsequent neutralization to obtain alcohol by fermentation.
