Problems solved by technology

With the advancement of science and technology, in addition to the deployment of sabinene in daily chemical flavors, sabinene can also be used as a synthetic raw material for food flavors. The content of sabinene in camphor oil is about 10∼15%. The method of distillation is used for the synthesis of sabinene in camphor oil. The sabinene is separated, and the purity of the separated sabinene is generally 70%-80%, and the sabinene with a purity close to 80% is called high-purity sabinene, and the distillation method makes it difficult to further improve the sabinene purity
[0004] At present, the application of camphor oil is concentrated on the rough extraction of crude oil. If the extraction process adopts steam distillation extraction, it is easy to cause the destruction of active components in camphor oil, resulting in a significant decrease in sabinene content; if the extraction process adopts the solvent extraction method Soxhlet extraction method, ultrasonic method, etc., because they involve the use of organic solvents, will cause great harm to the environment and safety

Embodiment 1

[0031]One embodiment of the present invention is a method of separating high purity thyene from the oil oil, comprising the step of: step a, refining the oil branch leaf, distilled with water vapor, condenses, and the oil is separated. Ethen oil; this mode of operation is performed by existing essential oil refining equipment, and its operation is a conventional manner, and then dried and pulverized and pulverized, and mixed with aqueous solution of sodium chloride. The existing water vapor distillation apparatus is distilled, continuously heated, is condensed by a condensing apparatus to obtain a liquid, and then a layer of oily material is taken, and the amount of anhydrous sodium sulfate is added to obtain an oil. It is to be noted that the oil fuel is usually within 1.5 hours of extraction time, and there is an increase in the extraction time with the increase of the extraction time, and the extraction time increases with the increase of extraction time. The reason why the gas t...

Embodiment 2

[0039]Based on the above embodiment, another embodiment of the present invention is that the second condenser is condensed when it is condensed against the light phase gas, and the content of more than 85% is stored in the material receiving tank by the optometry. The volatiles produced during the working process are output to the buffer tank through fine hydrazine, and the camrhyl liquid in the wafer is trapped, and the fine hydrazine is trapped to the abether liquid through the optometry to the material receiving tank. Its second condenser output of the extract is trapped to the thyristor liquid, and its form is transparent. Since the process is in a vacuum environment, there is a negative pressure flow in the gas phase flow, and the volatile material is prevented by the buffer tank and the fine hydrazine from flowing to the negative pressure device, and the gas phase output by the condenser can be subjected to a secondary separation of hot hydrazine. The liquid separated liquid c...

Embodiment 3

[0041]Based on the above embodiment, another embodiment of the present invention is that the pressure of 4000 Pa in the rectification column is 4000Pa, and the rectification column temperature in the rectification column is 70 degrees Celsius, the evaporation temperature of the column is 80 degrees Celsius, and the reflow ratio controller The reflow ratio is 5 to 1, the distillation time is 1 hour, the obtained liquid, the content of the thye is 70%; since the oil fuel is usually within 1 hour, within 1.5 hours, if the fine When the distillation time is less than 1 hour, the tamamob oil does not meet the relevant requirements in the extraction rate. The molecular distiller is a scraper film molecular distiller, and the scraper rotation speed is 400 r / min, since the film speed has a certain effect on the product yield, if the speed is less than 400R / min, the thickness of the formed film is large, the heat transfer is uneven, Efficiency and yield will decrease. Among them, the fee...

Abstract

The invention discloses a method and device for separating high-purity sabinene from cinnamomum longepaniculatum oil. The method comprises the following steps: refining cinnamomum longepaniculatum branches and leaves to obtain cinnamomum longepaniculatum oil, preheating the cinnamomum longepaniculatum oil, putting the preheated cinnamomum longepaniculatum oil into a rectifying tower, enabling the cinnamomum longepaniculatum oil to be in countercurrent contact with steam generated by a tower kettle to obtain crude sabinene liquid, processing the crude sabinene liquid by using a reflux ratio controller according to a set reflux ratio to obtain liquid to be refined, sending the liquid to be refined into a molecular distiller for secondary separation to obtain light-phase gas and heavy-phase liquid, injecting the heavy-phase liquid into a rectifying tower, and allowing the light-phase gas to pass through a second condenser so as to obtain sabinene liquid with a content larger than 85%. The device comprises the rectifying tower, a tower kettle, a first condenser, the reflux ratio controller, a distillation storage tank, the molecular distiller, a second condenser, a buffer tank and a material receiving tank, The problem that the purity of sabinene is lower than 80% when sabinene is extracted from cinnamomum longepaniculatum in an existing distillation mode is solved in the invention.

Description

Technical field[0001]The present invention relates to olene utilization and deep processing, and more particularly to methods and apparatus for separating high purity thread from tamamine oil.Background technique[0002]The shape of the oil is like a camphor, but the oil and camphor are different species, and the ingredients of the arambic oil have a large difference, the roots, branches, leaves and woods can extract soil. The main component of the oil is in accordance with leafellin and a terpenoid, and there is a inglene, a fridge or the like. With oil extracted with oil, it is mainly extracted by the oil in the oil, specifically, the taman oil is an aromatic essential oil secreted by the oil of the oil.[0003]In the oil, there is a plurality of components, except for the main components of 1,8-eucalyptus and a terpenoids, which can also be separated from a by-product. With the advancement of scientific and technological, amnee can also be used as a synthetic raw material for eating ...
