Description
Первыми Стади ми производства синтетической, аскорбиновой кислоты по йетоду Рейхштейна вл ютс : 1) каталитическое (с никелевым катализатором ) гидрирование глюкозы в водном растворе дл получени из глюкозы сорбита 2) биохимическое окисление сорбита в сорбозу.The first stages of the production of synthetic ascorbic acid by Reichstein are: 1) catalytic (with a nickel catalyst) hydrogenation of glucose in an aqueous solution to obtain sorbitol from glucose 2) biochemical oxidation of sorbitol to sorbose.
Сорбит после гидрировани получаетс в растворе, загр зненном никелем , который переходит в раствор в процессе каталитического восстановлени . Присутствие в растворе ионов никел угнетает жизнеде тельность микроорганизмов (Acetotecter melanogenum), примен емых дл окислени сорбита в сорбозу, что делает невозможным непосредственное окисление растворов, полученных после гидрировани .Sorbitol after hydrogenation is obtained in a solution contaminated with nickel, which goes into solution during the catalytic reduction process. The presence of nickel ions in the solution inhibits the viability of microorganisms (Acetotecter melanogenum) used to oxidize sorbitol to sorbose, which makes direct oxidation of solutions obtained after hydrogenation impossible.
Поэтому раствор сорбита обычно выпаривают, сорбит кристаллизуют из сиропа, после чего снова раствор ют в воде с получением 10-15процентного водного раствора, поступающего на окисление.Therefore, the sorbitol solution is usually evaporated, the sorbitol is crystallized from the syrup, after which it is redissolved in water to obtain a 10-15 percent aqueous solution fed to the oxidation.
По предлагаемому способу выпаривани раствора сорбита и кристаллизации его из спирта не производитс . Никель осаждают из полученного после гидр ровани раствора путем кип чени последнего сAccording to the proposed method, evaporation of the sorbitol solution and its crystallization from alcohol is not carried out. Nickel is precipitated from the solution obtained after the hydrolation by boiling the latter with
углекислым кальцием. Образовавшийс осадок основной углекислой соли никел отфильтровывают, фильтрат разбавл ют водой до концентрации , необходимой дл окислени , и в таком виде примен ют дл биохимического окислени .calcium carbonate. The precipitated basic carbonate of nickel is filtered off, the filtrate is diluted with water to the concentration required for oxidation, and in this form is used for biochemical oxidation.
Пример. В варочный котел емкостью около ido л загружают 25 л раствора технического сорбита (после гидрировани .глюкозы). В котел добавл ют 25 л воды и 1,25 кг мела в порошке. Перед добавлением в котел мел разбалтывают в 10 л раствора сорбита, вз того из котла. Полученную в котле смесь тщательно перемеши1вают и возможно быстро напревают до кипени . С момента начала кипени смеси, через каждые 10 минут, из котла отбирают пробу, в которой качественно определ ют присутствие никел .Example. A 25 l liter of a technical sorbitol solution (after hydrogenation of glucose) is loaded into a digester with a capacity of about ido l. 25 liters of water and 1.25 kg of chalk powder are added to the boiler. Before adding to the boiler, the chalk is broken into 10 liters of sorbitol solution taken from the boiler. The mixture obtained in the boiler is thoroughly stirred and possibly quickly cooked to a boil. From the moment the mixture begins to boil, every 10 minutes, a sample is taken from the boiler in which the presence of nickel is qualitatively determined.
После того как испытание на присутствие никел даст отрицательный результат, в смесь добавл ют 250 г активированного угл и К)И1п чение продолжают еще 10 минут . Активированный уголь перед подачей его в варочный котел предварительно - размешивают в отдельном сосуде в двух литрах вз той из котла смеси.After the test for the presence of nickel gives a negative result, 250 g of activated carbon are added to the mixture and K) And the injection continues for another 10 minutes. Activated carbon before feeding it to the digester is preliminarily stirred in a separate vessel in two liters of the mixture taken from the boiler.
Во врем нагревани и, особенно,During heating and especially
кип чени смеси происходит выделение углекислого газа, сонровождающеес сильным вспениванием. Поэтому нагревание и кип чение смеси должно производитьс осторожно под непрерывным наблюдением .boiling of the mixture results in the release of carbon dioxide, which generates strong foaming. Therefore, the heating and boiling of the mixture should be carried out carefully under continuous observation.
. Вспенивание устран етс энергичным перемешиванием и, в случае надобности, временным прекращением нагрева котла.. Foaming is eliminated by vigorous stirring and, if necessary, temporary cessation of boiler heating.
, После 10-минутного кип чени с активированным углем смесь выливают из котла и фильтруют на фильтре нутче.After boiling with activated carbon for 10 minutes, the mixture is poured out of the boiler and filtered on a suction filter.
Предмет и з о б .р е т е н и Способ очистки раствора технического сорбита, получаемого путем гидрировани глюкозы, от ионов никел , отличающийс тем, что Ысаждение никел производ т углекислым кальцием при нагревании .Subject and use. A method for purifying technical sorbitol solution obtained by hydrogenating glucose from nickel ions, characterized in that the precipitation of nickel is produced by calcium carbonate when heated.
