Description
Technical field
The utility model belongs to the chemical experimental instrument technical field, particularly a kind of laboratory volatile oil extractor.
Background technology
Volatile oil claims essential oil again, and English is essential oils, be present in a class in the plant have aromatic odour, can with wet distillation come out and with the general name of the not miscible volatility oily composition of water.Volatile oil is mixture, and its component is comparatively complicated; Mostly be colourless or the pale yellow oily liquid body, fragrance that many tools are special or sharp flavor; Proportion is soluble in dehydrated alcohol, ethers, chloroform, dithiocarbonic anhydride and the fatty oil between 0.850-1.180, is insoluble in water.
According to the volatilization oil properties, mainly from plant, extract and make by steam distillation and milling process.
Steam distillation is that the plant material that will contain volatile oil is placed on water proof heating in the vacuum tank, evaporates the volatile oil composition in the plant, and utilizes the type of cooling to make it to become liquid, separates according to the difference of the proportion of water and volatile oil, density again.
Milling process is that the plant material that will contain volatile oil squeezes, and through whizzer oily water separation is extracted volatile oil.
In addition, also can adopt grease partition method, and infusion method etc.The grease partition method is with the preferable part of fat absorption Scent, handles through alcohol, and stirs with machine, treat vaporized alcohol after, what stay is fragrant volatile oil.Infusion method is that plant materials such as flower are immersed in the deep fat, and the volatile oil in the plant is discharged, and refines with the distillation method extraction to get final product again.
In above-mentioned each method, the most frequently used is steam distillation, and most volatile oil all is to extract in this way to make.Steam distillation extracts the lab setup (as shown in Figure 1) of volatile oil and mainly is made up of 3 parts: water vapor generation device 1(is a water distilling apparatus), receiving trap 2(is volatile oil extractor, mainly comprise airway 4, inclined legs 5, graduated tube 6 and liquid storage tube 7, wherein airway 4 comprises vertical component 41 and sloping portion 42 again, the length summation of vertical component 41 and sloping portion 42, is that the total length of airway is usually greater than 5cm) and condensing works 3(prolong).
Water distilling apparatus 1(wherein also is volatile oil extractor or water vapor generation device sometimes) quality the extraction efficiency of volatile oil etc. is produced direct and significant influence.At present in the water distilling apparatus that the laboratory is used always, water vapor generation device adopts the single port flask usually, be difficult to guarantee lasting water vapour supply, minimizing along with the water yield in the water vapour producer, need to add once more for the distillation water, so just cause distillatory to interrupt, can not guarantee to distill the concrete time mensuration and fuel-displaced peak times scope accurate mensuration.
In addition, its receiving trap 2(is a volatile oil extractor) airway 4(or be the water vapour conduit) longer, condensation easily takes place in the air guide process, the volatile oil yield is reduced, also prolonged extraction time.Particularly when the higher material of distillation boiling point, before steam reaches side pipe, can not cooled off by the external world and reflux, cause and to distill.
The utility model content
Goal of the invention of the present utility model is: extract the problem of the lab setup existence of volatile oil at above-mentioned steam distillation, a kind of new laboratory volatile oil extractor is provided, can conveniently add for the distillation water, improve extraction efficiency etc.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:
A kind of laboratory volatile oil extractor, primary structure comprises water distilling apparatus, receiving trap and condensing works, and receiving trap comprises airway, inclined legs, graduated tube and liquid storage tube, and airway comprises vertical component and sloping portion; Wherein:
Water distilling apparatus is the flask with two openings, and opening I wherein is connected with receiving trap, and the opening II connects the long tube that a length is 10-30cm, can add from the long tube top for the distillation water.
The opening II of flask is used mainly as adding for the distillation water in the above-mentioned water distilling apparatus, the long tube of its connection can prevent also that simultaneously the water vapour that contains volatile oil from leaking from the opening II of flask, therefore, the length of this long tube is extremely important, too weak point does not then reach the effect that prevents that water vapour from leaking, oversize then waste material, increase cost, operation is also more inconvenient simultaneously.And, leaking by the opening II in order more effectively to prevent the water vapour that contains volatile oil, the long tube that is connected with the opening II can be preferably the prolong that matches.
Simultaneously, owing to add by the long tube that is connected with the opening II of flask for the distillation water, engler distillation in not needing in the interpolation process, can effectively guarantee the water vapour supply that continues, can guarantee to distill the concrete time and fuel-displaced peak times scope accurate mensuration, and can effectively improve the extraction efficiency of volatile oil.
Further preferred, the vertical component length of the airway of its receiving trap is 1-2cm.Promptly shorten the length of this part, and the length of inclined legs and graduated tube can remain unchanged even is longer.Behind the contraction in length of airway, in the air guide process, be difficult for condensation takes place, the volatile oil yield improved, and shorten extraction time; Be particularly suitable for the higher material of distillation extraction boiling point.
The beneficial effects of the utility model are:
The utility model laboratory volatile oil extractor, change flask into by single port flask with two openings with water distilling apparatus, and its opening II is connected with a long tube, can conveniently add for the distillation water, engler distillation in not needing, can effectively guarantee the water vapour supply that continues, can guarantee to distill the concrete time and fuel-displaced peak times scope accurate mensuration, and can effectively improve the extraction efficiency of volatile oil.
