Description
Technical field
The utility model belongs to natural products purification technique field, be related to it is a kind of can integration operation laboratory apparatus, especially
It is related to a kind of extraction of collection and steam distillation is separated into integrated experimental provision.
Background technology
There is various animals and plants in nature, contain a large amount of natural organic-compound, wherein mostly
The natural products that number is present in animals and plants each section tissue plays very important effect to human lives and production.So such as
What comes out these natural product extractions useful to the mankind and further purifying concentration is particularly important, early in 18th century
Mid-term, due to the requirement of the progress and social development of science and technology, the mankind have tentatively grasped extraction and the separation skill of natural products
Art, but latter stage in 18th century purer organic matter could be extracted from organism.For example, extracting winestone in earliest slave grape juice
Acid, extraction urea etc. in urine, until today, people are also extracting the natural production such as essential oil, alkaloid, flavones from animals and plants
Object.
Currently to there are many kinds of the extracting methods of natural products in animals and plants, for example, soxhlet extraction；Solvent extraction method；
Ultrasonic extraction；Microwave loss mechanisms etc., experiment at present is Soxhlet extractor using more extracting method.Soxhlet extractor is
Using the principle of reflux and the siphon of solvent, required natural component in solid mixture is continuously extracted, extraction is worked as
When the solvent liquid level got off that flows back in cylinder is more than the siphon of Soxhlet extractor, the solvent extracted in cylinder can flow back to round-bottomed flask
It is interior, that is, siphon has occurred.With the raising of temperature, it may appear that flow back again, before each siphon, the solid material for extraction is all
Can extraction preferably be impregnated by hot solvent, solvent can be recycled, and the waste of solvent is reduced.Its disadvantage is：Soxhlet extraction
Device price is costly；It is easy to be broken during use that whole experiment process is caused to terminate, some unnecessary losses can be brought；
The raw material of extraction must be wrapped up with filtration paper cylinder；The folding of filtration paper cylinder needs the time to complete, and causes the extension of experimental period；
If excessively tight to extraction raw material wrapping, can cause fully contact between raw material and solvent so that product cannot be by
It is completely dissolved out；Likewise, the product extracted easily and effectively cannot carry out isolating and purifying can lead to that extraction is greatly reduced
Rate.The structure of existing Soxhlet extraction device is as shown in Figure 1.
The method that liquid isolates and purifies at present mainly distill, including steam distillation, air-distillation, vacuum distillation, plus
Pressure distillation and molecular distillation etc., steam distillation is to be passed through insoluble by vapor or be insoluble in the organic matter of water so that is had
Machine object at a lower temperature, as temperature gradually increases organic matter and the equal rapid evaporation of water in raw material, generates mixed vapour,
Organic matter is allowed to be distilled off together with vapor.The structure of existing steam distillation device is as shown in Fig. 2, its device exists
Certain shortcoming, such as：Steam evaporator is unable to continuous supplementation moisture during the work time can lead to the vapor generated
Air Bubble Size differs, and speed speed differs, and is unfavorable for the progress of experiment；The existing steam evaporator used is mostly iron flask, is made
With can get rusty too long, and iron flask inconvenience is connect with grass tube；Its extraction process time is longer, temperature is high, open system,
Destruction and the volatilization loss of thermally labile component and oxidizable ingredient are easily caused in the process；Existing steam distillation can only be collected into
With the product that vapor evaporates together, and remaining fixedness product can be wasted；Under normal circumstances in order to concentrate
Distilled out product, mixed solution is also first taken out to be then transferred to afterwards in other distilling apparatus again steamed with purifying
It evaporates so that the product extracted is further concentrated.
Air-distillation is the common method of separation and purification of liquid organic matter, has different boilings using different liquid
Point is to separate two or more component.The solvent used in extraction process can be removed by distillation, allows and is carried
The natural products obtained further concentration and purifying, to improve the purity and yield of natural products.Certain higher boilings are natural
It is heated under product normal pressure and is also not up to the phenomenon that boiling point decomposition, oxidation has just occurred or polymerize, in order to avoid these phenomenons
Vacuum distillation can be used.From the point of view of current decompression distilling apparatus, each section instrument is single to be assembled shared by use
Space it is bigger, cause the waste of lab space, connect the longer holding for being unfavorable for vacuum condition of pipeline of each section.It is existing
The structure of vacuum distillation apparatus is as shown in Figure 3.
From currently to animals and plants in from the point of view of the extraction purification of natural organic matter and the instrument and equipment of concentration, to most natural
The extraction purification of organic matter and concentration are all single progress step by step, to realize and quickly complete extraction purification and to concentrate this several
The integration operation of a experimental procedure is relatively difficult.More set experimental instrument and equipments must be assembled in order to reach experiment purpose,
It is more complicated time-consuming in experimentation, cause certain wasting of resources, while cover experimental provision using more pendulum can be occupied
Between emptying, lead to the waste of lab space.These experimentations are concentrated in conjunction with the extraction and purifying of natural organic-compound
Principle and feature, the extraction purification of natural organic matter and concentration are innovatively connected and designs a kind of collection and extracts and water
Steam distillation is separated into integrated experimental provision, has certain urgency and practicability.
