Description

СПОСОБ НЕПРЕРЫВНОГО ИЗВЛЕЧЕНИЯ ВЕЩЕСТВ ИЗ ИХ ВОДНЫХ РАСТВОРОВMETHOD OF CONTINUOUS EXTRACTION OF SUBSTANCES FROM THEIR AQUEOUS SOLUTIONS

За влено 18 ма  1945 года за X 5058/338274 в Народный Комиссариат здравохранени  СССРIt was announced on May 18, 1945 for X 5058/338274 to the People's Commissariat of Health of the USSR

Экстракци  органических веществ из нх водного раствора, например экстракци  кофеина из его водного раствора хлороформом, ведетс  в насто ихе.е врем  в экстракционных колоннах с насадкой высотой 6-7,и. При этом хлороформ вводитс  в жидком виде, а процент извлечени  кофеина составл ет в среднем 85°о.The extraction of organic substances from the aqueous aqueous solution, for example, the extraction of caffeine from its aqueous solution with chloroform, is currently carried out in extraction columns with a nozzle height of 6-7, and. In this case, chloroform is introduced in a liquid form, and the percent recovery of caffeine is on average 85 ° C.

Известно также экстрагирование водных растворов органическими растворител ми, которые ввод тс  не в жидком, а в парообразном состо нии- Предлагаетс  последний способ экстрагировани  осуществл ть в бозпасадочном аппарате колонного типа с холодильником внутри. Опыты, П1ювсденные в лабораторной колонне, показали, что данный способ илгеет сун ествениые преимущества перед существуюнщми: производительность колонны увеличиваетс  в 5-6 раз; высота колонны 3,5-И, вместо G-7.и; отсутствие насадки дает возможность при промывке колонны не останавливать ее работу; извлечение составл ет 95% вместо 85%; расход хлороформа-75% вместо 120% (по объему.It is also known to extract aqueous solutions with organic solvents, which are introduced not in a liquid, but in a vapor state. The latter method of extraction is proposed to be carried out in a batch recovery apparatus of a column type with a cooler inside. Experiments carried out in a laboratory column showed that this method has superior advantages over existing ones: the productivity of the column increases 5–6 times; the height of the column is 3.5-I, instead of G-7.i; the absence of the nozzle makes it possible not to stop its operation when flushing the column; recovery is 95% instead of 85%; chloroform consumption is 75% instead of 120% (by volume.

Свежий водный раствор, например кофеина, вводнтс  в колонну снизу. На высоте 0,75-1,0л1, от дна ввод тс  пары растворител  (хлороформа ) через барботер. Пары хлороформа барботируют через водный раствор, поднимаютс  снизу вверх, конденсируютс , при чем происходит экстракци  кофеина, т- е. переход кофеина из водного сло  в хлороформ, и конденсат стекает вниз.A fresh aqueous solution, such as caffeine, is introduced into the column below. At a height of 0.75-1.0 L1, solvent vapors (chloroform) are introduced from the bottom through a bubbler. Chloroform vapor is bubbled through the aqueous solution, rises from the bottom up, condenses, removing the caffeine, i.e. the transfer of caffeine from the aqueous layer to chloroform, and the condensate drains down.

Так как при конденсации хлороформа водный слой нагреваетс , то над первым барботером устраиваетс  холодильник. Водный слой, после первого барботера, проходит холодильник и встречаетс  с парами хлороформа, вводимыми через верхний барботер. Здесь происходит втора  экстракци . Обработанный раствор вытекает из колонны сверху, хлороформ же с растворенным в нем кофеином вытекает снизу в приемник , откуда перетекает в испарительСпособ непрерывного извлечени  веществ из их водных растворов органическими летучими растворител ми путем введени  последних в водный раствор в парообразном состо нии, отличающийс  тем, что через аппарат колонного типа, снабженный змеевиковым холодильником , непрерывно пропускают водный раствор вещеспва и пары органического растворител .Since the aqueous layer is heated by condensation of chloroform, a refrigerator is arranged above the first bubbler. The aqueous layer, after the first bubbler, passes through a cooler and is encountered with chloroform vapor introduced through the upper bubbler. Here is the second extraction. The treated solution flows from the top of the column, while chloroform, with caffeine dissolved in it, flows from the bottom to the receiver, from which it flows into the evaporator. The method for continuously removing substances from their aqueous solutions with organic volatile solvents by introducing the latter into the aqueous solution in vapor form, the apparatus of the column type, equipped with a coil cooler, continuously passes an aqueous solution of the substance and two vapors of an organic solvent.
