Description
Одной ИЗ стадий синтеза аскорбиновой кислоты вл етс ацетонироваиие сорбозы. При этом нар ду с Д1гацетоисорбозой, нужной дл получени аскорбиновой кислоты, образуетс моноацетонсорбоза, вл юща с неиснользуемым отходом. Известен способ разделени продукто ; цетонировани сорбозы, основанной на способности концентрированных щелочей высаливать диацетоисорбозу. Этот способ прин т па всех отечественных заводах, синтезнругоплих витамин С.One of the stages of the synthesis of ascorbic acid is the acetonation of sorbose. At the same time, along with D1hacetoisorbose, which is necessary for the preparation of ascorbic acid, monoacetone-sorbose is formed, which is an unused waste. A known method of product separation; cetonating sorbose based on the ability of concentrated alkalis to salve out diacetoisorbose. This method is accepted in all domestic factories, synthesized vitamin C.
Предлагаетс способ разделени продуктов ацстопировапи сорбозы путем высаливани диацетопсорбозы растворол сернокислого натри с образованием после отгонки ацетона сло сирона диацетоисорбозы и сло водного солевого раствора, содержащего моноацетонсорбозу; при iiTOM моноацетонсорбоза легко извлекаетс дл носледующего доацетоинровани .A method is proposed for separating sorptose adsorption products by salting out diacetopsorbose solution of sodium sulfate to form, after distillation of acetone, a layer of sirona diacetoisobose and a layer of an aqueous salt solution containing monoacetone adsorphosis; at ii-TOM, mono-acetone-sorbose is easily recovered for the next up to acetoin.
Предлагаемый способ более прост и рационален, так как за счет извлечени мо юацетонсорбозы и ее доацетонироваии выход диацетонсорбозы повы1иастс на 14-16/о.The proposed method is simpler and more rational, since, due to the extraction of my jucetone-adsorbose and its pre-acetonation, the output of diacetone-sorbose increases by 14-16 / o.
Суниюсть способа заключаетс в том, что . после обычно проведенной реакции ацетонировани сорбозы ацетоновый раствор продуктов ацетоиироваии нанр вл етСЕ пр мо на отгонку ацетона (вместе с сульфатами). После этого в смесь добавл етс вода дл образовани наcbinxeinioro при 36 водного раствора сернокислого натри . Диацетоисорбоза в виде сирона всплывает моноацетонсорбоза jia поверхность, (при щелочности i солевого раствора 2-3%) остаетс в этом растворе.The simplicity of the method is that. After the usually carried out acetonation of sorbose, the acetone solution of the products of acetonation and nanrillium are directly to the distillation of acetone (together with sulfates). Thereafter, water is added to the mixture to form ncbinxeinioro with 36 aqueous solution of sodium sulfate. Diacetoisorbose in the form of a sirone monoacetone-sorbose jia surface emerges (with alkalinity i saline solution of 2-3%) remains in this solution.
Очищенный сироп диацетонсорбозы передаетс на фазу окислени . Раствор сернокислого натри нейтра .тизуетс до Н1,елочиости 0,2-0,5% i-i из него 2-кратиой промывкой ацеTOiroM извлекаетс моноацетонсорбоза , котора в дальнейн1ем нзвест (ым способом ацетонмруетс в днацетонсорбозу .The purified diacetone sorbose syrup is transferred to the oxidation phase. The sodium sulphate solution is neutralized to H1, 0.2-0.5% i-i of woodness from it, a 2-fold wash of the acetoim is extracted with mono-acetone adsorphosis, which is further known (it is acetone in bottom acetone adsorphosis.

Способ разделени нродуктов ацетоиироваии сорбозы путем высаливани диацетонсорбозы. о т л и ч аю щ и и с тем, что, с целью улучпюки выхода и упрощени процесса, высаливание диацето1гсорбозы осуществл ют раствором се)нокислого натри с образованием после отгонки ацетоиа сло сиропа диацетонсорбозы и сло водного солевого раствора, содержап:.его моноацетоисорбозу .A method for separating acetoyirovor sorbose products by salting out diacetone adsorbose. This is so that, in order to improve the output and simplify the process, the salting out of diaceto1 sorption is carried out with a solution of sodium sulfate to form, after the distillation of the acetoacetate, a diacetone adsorbose syrup and a layer of an aqueous salt solution containing: .
