Soxhlet extraction is a kind of classical way of extract compounds from solid matter, extracts and realizes by apparatus,Soxhlet's.This method is utilized solvent refluxing, and solid matter is continuously extracted by neat solvent, has not only saved solvent extraction efficient but also high.Apparatus,Soxhlet's structure commonly used as shown in Figure 1, extraction will be extracted when extracting and be placed in the filter paper cover after solid material is pulverized, put into apparatus,Soxhlet's, the connected round-bottomed flask that extractant is housed in heating bottom, solvent boiling back steam rises with the extractor arm, behind connected condensing tube condensation, splash into extractor, contact with extract and to extract, when the solvent face surpassed the siphon pipe highest point, the solvent siphon that the contains extraction component bottle that flashes back so repeated, make extract constantly by pure solvent extraction, extraction component is enriched in the flask.Patent of invention CN201500467U has announced a kind of apparatus,Soxhlet's that is incubated, and structure by bilayer sleeve heat collecting type apparatus,Soxhlet's, utilizes solvent to evaporate the steady temperature that the heat that produces keeps solvent as shown in Figure 2.
Traditional apparatus,Soxhlet's is subjected to the temperature effect of the environment of placing, and the solution heat constantly is lost in the air in the cavity, and temperature decreases; Simultaneously, the extractant Steam Heating that cavity bottom is risen, temperature rises to some extent.More than two kinds of factor actings in conjunction, can cause the continuous variation of extraction temperature, influence the stability of extraction efficiency and extraction process.Though patent CN201500467U has partly solved the extraction temperature problem of unstable, because cavity is extracted the solvent vapo(u)r heating, extractant remains on higher temperature, is not suitable for the extraction of temperature unstable material.
Summary of the invention
The object of the present invention is to provide a kind of Temperature Control Type apparatus,Soxhlet's that can control the extraction process temperature.
The present invention is by the following technical solutions:
A kind of Temperature Control Type apparatus,Soxhlet's, comprise outer tube and interior pipe that suit forms, one end of outer tube is provided with the temperature control liquid-inlet, the other end is provided with the temperature control liquid outlet, the outer tube below is provided with the ground link, be provided with arm between interior pipe top and the ground link, interior pipe bottom is provided with siphon pipe, siphon pipe inserts in the ground link after passing outer tube rising inflection, be provided with coiled pipe between outer tube and the interior pipe, in the interlayer of the body of coiled pipe between outer tube and interior pipe, the import and the outlet of coiled pipe are positioned at pipe, the import of coiled pipe is higher than the outlet of arm, the height that sample was placed in the pipe in the outlet of coiled pipe was higher than.
The import of described coiled pipe and outlet are convenient to place sample in the inside pipe near the madial wall of interior pipe.
The import of described coiled pipe is an infundibulate.
The upper end ground of pipe is connected with condenser pipe in described, and the ground link is connected with round-bottomed flask, the import of coiled pipe be positioned at that condenser pipe exports under.
The present invention is provided with the outer tube of suit outside interior pipe, the interlayer circulation has temperature control liquid between outer tube and the interior pipe, guarantee in making and hold certain temperature, be provided with coiled pipe between outer tube and the interior pipe, in the interlayer of the body of coiled pipe between outer tube and interior pipe, the solvent of condensing reflux is managed in flowing into behind coiled pipe, and condensed like this solvent also is controlled at certain temperature through temperature control liquid, thereby makes extraction process carry out under the temperature of needs.
The concrete operation principle process of the present invention is: the upper end of interior pipe connects condenser pipe, the ground link of outer tube below is connected with round-bottomed flask, temperature control liquid enters the inner and outer pipes interlayer by the temperature control liquid-inlet of outer tube, interlayer is full of, flow out from the temperature control liquid outlet again, enter interlayer once more through after the adjustment, temperature control is carried out in circulation; The heating round-bottomed flask, solvent vaporization in the round-bottomed flask enters condensing tube condensation after arm rises, condensate liquid refluxes and splashes into the coiled pipe import, through pipe in returning behind the solvent temperature control in the interlayer sample is extracted, when the extract in the interior pipe reached siphonal peak, extract was returned in the round-bottomed flask by siphon, so repeatedly, make extract constantly by pure solvent extraction, extraction component is enriched in the extraction that realizes in the flask sample.
The present invention can be per sample to the requirement of extraction temperature, select suitable temperature control liquid, by temperature control liquid is remained on steady temperature, internally pipe and coiled pipe heat or cool off temperature control, thereby the temperature of extract in the pipe in the control, guarantee the stability of extraction process, the material higher to temperature stability, adopt higher temperature to extract, improve extraction efficiency,, can adopt lower temperature to extract for the relatively poor material of temperature stability, avoid it that chemical change takes place, realize the extraction process temperature controlling.
