Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope is not limited by the specific implementation.
A kind of Experiment of Organic Chemistry water segregator, it is specific as shown in Figure 1, including collector tube 1, the top of collector tube 1 is equipped with
First adapter 2, bottom end is equipped with return tube 3, and return tube 3 is connected to collector tube 1；The side of collector tube 1 is equipped with steam pipe 4,
The upper end of steam pipe 4 is connected to the upper end of collector tube 1, and lower end is connected to the lower end of return tube 3；On collector tube 1 with 4 phase of steam pipe
Pair side be equipped with return pipe 5, one end of return pipe 5 be connected to the lower end of collector tube 1, the upper end company of the other end and return tube 3
It is logical；
Return pipe 5 has upper pipes and lower end pipe, and is connected between upper pipes and lower end pipe by tee tube 6, tee tube 6
Third liquid outlet be communicated with drainpipe 7；Drainpipe 7 is equipped with the first valve 8, and the lower section of tee tube 6 is located on return pipe 5
Place is equipped with the second valve 9, and return tube 3 is equipped with third valve 10, and third valve 10 is located at the top of return pipe 5；Return tube 3
Bottom end be equipped with the second adapter 11.
In the utility model when in use, water segregator is fixed on to the top of reaction vessel by fixed device, and
It is connected with condenser pipe on first adapter 2, is connected with reaction vessel on the second adapter 11.Reaction vessel is in heating reaction process
In, organic solvent in the moisture and system of generation high temperature evaporation together is escaped up from steam pipe 4, into collector tube 1, collection
The air cooling effect of liquid pipe 1 collects in collector tube 1 after can making a part of Mixed Gas Condensation, and the mixed gas not being condensed exists
Be condensed pipework condensation in uphill process, flows back into collector tube 1.
Collector tube 1 can by condensate liquid water and organic solvent separate, to guarantee that organic solvent can flow back into instead
Container is answered, and by-product water is then collected separately, and organic reaction is not continued to participate in.
Collector tube 1 works as condensation before use, the first valve 8, the second valve 9 and third valve 10 are in closed state
When the density of organic solvent is greater than the density of water in liquid, organic solvent is located at the lower part of collector tube 1, and water is then located at collector tube 1
Top, when condensate liquid savings in collector tube 1 to it is a certain amount of when, the layering of organic solvent and water is obvious, and when water layer
Lowest order is in return pipe 5 hereinafter, opening the first valve 8, and the second valve 9 and third valve 10 is kept to close, at this time can be with
By the water put aside in collector tube 1 be discharged, until drain into water layer highest order it is concordant with return pipe 5 when, opening third valve 10, simultaneously
