Description
Активированный уголь вл етс прекрасным средством дл очистки растворов витамина С от нежелательных примесей (крас щих веществ к пр.), однако он обладает в отношении аскорбиновой кислоты двум нежелательными свойствами, благодар которым его применение дл указанной цели не могло «меть места, а именно: активированный уголь с од юй стороны энергично окисл ет витамин С, перевод его в дегидроформу, с другой стороны он может адсорбировать аскорбиновую кислоту, поглоща ее из чистых растворов в количестве от 80 до 200 мг на 1 г угл , в зависимости от активности последнего.Activated carbon is an excellent means for cleaning solutions of vitamin C from undesirable impurities (coloring agents, etc.), but it has two undesirable properties with respect to ascorbic acid, due to which its use for this purpose could not mark the place, namely: activated carbon from one side vigorously oxidizes vitamin C, converting it into dehydroform, on the other hand, it can adsorb ascorbic acid, absorbing it from pure solutions in an amount of from 80 to 200 mg per 1 g of coal, depending from the activity of the latter.
Известно, что обработка активирован ного угл гидросульфитом; натри устран ет лишь окисл ющее действие угл , предлагаемый же способ устран ет адсорбцию аскорбиновой кислоты без существенного понижени активности угл в отношении нежелательных примесей. Способ отличаетс тем, что в подлежащие очистке растворы или выт жки витамина С, перед фильтрованием через уголЬ, добавл етс 20-25% этилового спирта или 2- 3%, yKtycHO-этилового эфира. Выход витамина С почти количественный 90- 95%, если концентрации витамина не слишком низки; при малых концентраци х относительные потери возрастают .It is known that the treatment of activated carbon with hydrosulfite; sodium only eliminates the oxidizing effect of coal, while the proposed method eliminates the adsorption of ascorbic acid without significantly reducing the activity of the coal with respect to undesirable impurities. The method is characterized in that 20-25% of ethyl alcohol or 2-3% of y KtycHO ethyl ether is added to the solutions to be purified or drained of vitamin C before filtering through the corner. The yield of vitamin C is almost quantitative 90-95%, if the concentration of the vitamin is not too low; at low concentrations, the relative losses increase.
Предмет изобретени .The subject matter of the invention.
Способ очистки водных выт жек витамина С с помощью активированного угл , отличающийс тем, что, с целью устранени адсорбции витамина утлем, к водной выт жке витамина С, перед фильтрованием через уго-ль, прибавл ют этиловый спирт в количестве 20-25% всей смеси или уксусно-этиловый эфир в количестве 2-3% всей смеси.The method of purifying aqueous extracts of vitamin C using activated carbon, characterized in that, in order to remove vitamin adsorption from the vitamin, 20-25% of the whole mixture is added to the aqueous extract of vitamin C before filtering through the angle. or ethyl acetate in the amount of 2-3% of the mixture.
