Description
Как известно, дл извлечени эвгенола и других фенолов из соответствующих эфирных масел последние обрабатывают раствором щелочи, превраща таким образом фенолы в фенол ты , водные растворы которых в дальнейщем отдел ютс от непрореагировавщей части масла и подкисл ютс дл выделени свободных фенолов.As is known, to extract eugenol and other phenols from the corresponding essential oils, the latter are treated with an alkali solution, thus converting the phenols into phenols, the aqueous solutions of which are further separated from the unreacted part of the oil and acidified to release free phenols.
Согласно насто щему изобретению, щелочной обработке дл извлечени фенолов подвергают смесь паров воды и эфирных масел, получаемую при отгонке последних из эфироносов в токе вод ного пара.According to the present invention, a mixture of water vapor and essential oils is obtained by alkaline treatment for the extraction of phenols, which is obtained by distilling the latter from ether beads in a stream of water vapor.
Этот способ обладает значительным преимуществом по сравнению с обычной щелочной экстракцией эфирных масел в жидкой фазе, особенно в случае переработки эвгенольного базилика , так как таким путем содержащиес в эфироносах фенолы могут быть извлечены почти без потерь. Как известно , уд. вес масла эвгенольного базилика весьма близок к уд. весу воды (1,01 -1,02). Вследствие этого при отгонке масла образуетс устойчива эмульси , котора очень плохо расслаиваетс . Это влечет за собой значительные потери масла (а следователь-, но, и эвгенола), которое в виде эмульсии выводитс из приемников. Если же примен ть щелочную экстракцию эфирных масел в паровой фазе, то потери свод тс к минимуму.This method has a significant advantage compared to the conventional alkaline extraction of essential oils in the liquid phase, especially in the case of processing eugenol basil, since in this way the phenols contained in the ether lines can be extracted almost without loss. As you know, beats. The weight of Eugenolian basil oil is very close to the beats. weight of water (1.01 -1.02). As a result, during the distillation of the oil, a stable emulsion is formed, which splits very poorly. This entails a significant loss of oil (and therefore, but also of eugenol), which in the form of an emulsion is removed from the receivers. If, however, alkaline extraction of essential oils in the vapor phase is used, the losses are minimized.
Дл щелочной экстракции можно примен ть водные растворы едких щелочей , концентраци которых должна быть не ниже 20%.For alkaline extraction, aqueous solutions of caustic alkalis can be used, the concentration of which should not be lower than 20%.
Можно также воспользоватьс дл св зывани фенолов известковым молоком или даже примен ть сухой гидрат окиси кальци .You can also use calcium milk to bind the phenols with lime milk, or even use dry calcium hydroxide.
При этом выпадет твердый и плохо растворимый в воде эвгенол т кальци .This will precipitate solid and poorly soluble calcium eugenolate in water.
Дл того, чтобы предотвратить разложение фенол тов при действии пара, необходимо, чтобы щелочь в поглотительном аппарате находилась в значительном избытке.In order to prevent the decomposition of phenols under the action of steam, it is necessary that the alkali in the absorption apparatus be in a considerable excess.
В частности дл эвгенол та необходимое количество щелочи к концу отгонки должно быть пе ниже тройного количества щелочи, теоретически необходимого дл св зывани всего эвгенола .In particular, for an eugenolate, the necessary amount of alkali by the end of the distillation should not be lower than the triple amount of alkali, theoretically necessary for the binding of all eugenol.
