Description
Technical field
The utility model relates to a kind of nitrogen protection reaction units.
Background technique
For being exposed to the compound of easy in inactivation or organic reaction under moisture or oxygen atmosphere, need to protect in nitrogen atmosphere
Lower reaction can just be able to high yield and generate object.It is carried out since organic reaction would generally add organic solvent, therefore reaction vessels
Bottleneck should not use rubber bottle stopper, and existing laboratory nitrogen protection device in the port of reaction vessels mostly by directly setting
Set threeway glass valve and by the valve connection nitrogen balloon, but the cooperation leakproofness of threeway glass valve and bottleneck compared with
Difference is easy to cause helium leak.
Utility model content
To solve the above problems, the utility model proposes a kind of nitrogen protection reaction unit, good airproof performance, and structure letter
It is single, easy for installation, at low cost, it can be used as the assistant experiment tool of laboratory anhydrous and oxygen-free organic reaction.
The utility model proposes a kind of nitrogen protection reaction units, including flask, cork, bilateral piston and nitrogen gas
Ball；The connection of the bottleneck of the cork and flask, the cork are equipped with through-hole；The bilateral piston is the piston for including transverse direction
Head, the first siphunculus with connection at the top of piston head, and the second siphunculus with piston head bottom connection, second siphunculus and institute
Through-hole interference fit is stated, which extends to the neck of flask through the through-hole, and the nitrogen balloon is logical with described first
Pipe connection.
Further, the junction of the nitrogen balloon and the first siphunculus be equipped with fixing clamp or sealing sticker, further plus
Strong sealing.
Further, first siphunculus and the second siphunculus are glass tube, since the second siphunculus of glass material extends to bottleneck
It will not be influenced by reactant.
Further, the piston head is ground glass piston head, is integrally formed with the first siphunculus and the second siphunculus.
Further, the cork is taper mesa-shaped, is applicable in various sizes of bottleneck, guarantees to be interference fitted with bottleneck,
It is sealed, and cork is not influenced vulnerable to volatile solvent.
Further, the flask is round-bottomed flask, boiling flask or three-neck flask.
The beneficial effects of the utility model：The utility model burns nitrogen balloon by bilateral piston, cork and round bottom
Bottle is connected, and is in reaction system under the protection of nitrogen, thus completely cut off the influence of vapor and oxygen to experiment in air,
Good airproof performance, nitrogen air inflow can be adjusted by piston head, improve the reaction yield of object, and structure letter to greatest extent
It is single, easy for installation, at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As follows in conjunction with attached drawing, application scheme is further described：
Referring to attached drawing 1, a kind of nitrogen protection reaction unit, including flask 1, cork 3, bilateral piston 2 and nitrogen balloon
4.The flask 1 is round-bottomed flask.The cork 3 is taper mesa-shaped, and the cork 3 plug connects in the bottle mouth position of flask 1 with it
It connects, the cental axial position of the cork 3 is equipped with through-hole 31.The bilateral piston 2 is the piston head 21 for including transverse direction, with piston head
First siphunculus 22 of 21 top connection, and the second siphunculus 23 with 21 bottom connection of piston head, first siphunculus 22 and
Bipass 23 is glass tube, and the piston head 21 is ground glass piston head.Second siphunculus 23 and 31 interference of through-hole
Cooperation, second siphunculus 23 extend to the neck of flask 1 through the through-hole 31.Nitrogen, lower end are full of inside the nitrogen balloon 4
Gas outlet is set in 22 upper end of the first siphunculus, connect sealing with the first siphunculus 22 using 4 natural resiliency of nitrogen balloon, and adopt
Junction is wrapped in sealing sticker 5 and further seals fixation, or is added fixing clamp in the junction and be sealed fixation.
In use, first reactant 6 is placed in flask 1, then the cork 3 for having plugged bilateral piston 2 is fixed on flask 1
Then nitrogen balloon 4 is set in 22 upper end of the first siphunculus to being interference fitted by bottleneck, plug, be wrapped in connection with sealing sticker 5
Place, then by the air inflow of the adjusting nitrogen of rotary-piston head 21, can be reacted.
Nitrogen balloon 4 is connected by bilateral piston 2, cork 3 with round-bottomed flask 1, is made by this nitrogen protection reaction unit
Reaction system is under the protection of nitrogen, thus completely cut off the influence of vapor and oxygen to experiment in air, good airproof performance,
The reaction yield of object is improved to greatest extent, and structure is simple, easy for installation, at low cost.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Same, approximate or technology deduction, replacement, improvement for making based on this etc., are regarded as the protection scope of this patent.
