Description
При получении лимонной кислоты из табачного сырь , в частности махорки , согласно авторскому свидетельству № 30272 сырье экстрагируетс разбавленными кислотами.Upon receipt of citric acid from tobacco raw materials, in particular, tobacco products, according to the author's certificate No. 30272, the raw materials are extracted with diluted acids.
Затем экстракт обрабатываетс мелом или известью дл перевода лимонной кислоты в цитрат кальци , который отфильтровываетс . В ф(и.Шзтрате остаетс никотин, извлеченный из табачного сырь .The extract is then treated with chalk or lime to convert citric acid to calcium citrate, which is filtered. Nicotine extracted from raw tobacco is left in the f.
Насто щее изобретение относитс к выделению никотина из фильтратов после отделени лимонной, а также блочной кислоты. Дл этой цели фильтраты подщелачивают едкой щелочью или известью, а затем упаривают.The present invention relates to the recovery of nicotine from filtrates after separation of citric acid and also malic acid. For this purpose, the filtrates are alkalized with caustic alkali or lime, and then evaporated.
При этом никотин переходит в дестиллат, из которого он «(никотин) извлекаетс известными приемами.At the same time, nicotine is transferred to the distillate, from which it "(nicotine) is extracted by known methods.
Можно обработать дестиллат активированным углем, который адсорбирует никотин. Дл выделени никотина из угл , последний обрабатывают перегретым паром, который провод т затем через нагретый до 100° концентрированный раствор серной кислоты. При этом сразу получаетс технический никотинсуль. фат.You can treat the distillate with activated carbon that adsorbs nicotine. To release nicotine from coal, the latter is treated with superheated steam, which is then passed through a concentrated solution of sulfuric acid heated to 100 °. In this case, technical nicotinsul is immediately obtained. Fat
Можно также экстрагировать, никотин из угл органическими растворител ми , например, керосином.It is also possible to extract nicotine from coal with organic solvents, for example, kerosene.
При известном способе отгонки никотина в токе вод ного пара непосредственно из табачного сырь требуетс весьма значительный расход пара. Процесс отгонки весьма продолжителен, а концентраци никотина в дестиллате очень мала .With the known method of distilling nicotine in a stream of water vapor directly from tobacco raw materials, very significant consumption of steam is required. The distillation process is very long, and the concentration of nicotine in the distillate is very small.
Поэтому на практике такой паровой отгонке никотина предпочитают пр мое экстрагирование его кз подщелоченного табака органическими растворител ми. Затруднени , имею, щие место при отгон1ке никотина в токе вод ного пара непосредственно из сырь , объ сн ютс тем, что коллоидна масса (растительного материала в значительной степени адсорбирует никотин и уменьшает его летучесть с паром.Therefore, in practice, such steam distillation of nicotine is preferred to the direct extraction of its solid state alkaline tobacco with organic solvents. Difficulties that occur during the distillation of nicotine in a stream of water vapor directly from the raw material are due to the fact that the colloidal mass (of plant material largely adsorbs nicotine and reduces its volatility with steam.
Согласно, предлагаемому способу никотин отгон етс из среды, не содержащей коллоидов.According to the proposed method, nicotine is distilled off from a medium not containing colloids.
Поэтому отгонка никотина протекает быстро получаютс деетиллаты с 4-5%-ным содержанием никотича , что не может быть достигнуто при непосредственной отгонке никотина из табачного сырь .Therefore, nicotine distillation proceeds quickly with deethyls with a 4-5% nicotichic content, which cannot be achieved by directly stripping nicotine from tobacco raw materials.
Предмет изобретени Subject invention
Способ извлечени никотина из табачного сырь с применением отгонки его в токе вод ного пара, отличающийс тем, что ука107 занной обработке подвергают экстракт , получаемый при -извлечении лимонной кислоты из табачного сырь обработкой последнего разбавленными кислотами, после выделени из него (экстракта) лимонной и блочной кислот и последующего подщелачивани .A method of extracting nicotine from tobacco raw material using its stripping in a stream of water vapor, characterized in that the extract obtained by α-extracting citric acid from the tobacco raw material by treating the latter with dilute acids is subjected to processing, after isolating it from the acids and subsequent alkalinization.
