Description
Technical Field
The utility model belongs to the experimental facilities field, concretely relates to nitrogenous class compound technology improves desolventizing device.
Background
In a micro organic chemical reaction, particularly in a milligram-scale or milliliter-scale reaction, because the feeding and reaction solvents of the reaction are very little, the sample after the reaction is subjected to desolventizing treatment by using desolventizing equipment in the existing laboratory, such as a rotary evaporator and the like, and the solvent is hardly desolventized and completely removed without paying attention, so that only a trace sample is hardly visible on the wall of a flask, and the sample is difficult to collect. Particularly, in the case of nitrogen-containing compounds, the sample is easily destroyed or decomposed during drying.
Disclosure of Invention
The utility model aims at providing a desolventizing device for improving the process of nitrogenous compounds, which can more conveniently process the desolventizing of trace chemical products, based on the prior art.
The technical scheme of the utility model is that:
a technological improvement desolventizing device for nitrogen-containing compounds comprises a sample tube, a needle head, a flanging plug and an explosion-proof ball, wherein one end of the flanging plug is connected with an opening of the sample tube, the other end of the flanging plug is connected with a gas inlet of the explosion-proof ball, and two foldable skirt edges of the flanging plug are respectively wrapped on the outer walls of the opening of the sample tube and the gas inlet of the explosion-proof ball; the needle head is inserted into the plug cover of the turnover plug, the needle tip part of the needle head is positioned in the sample tube, and the connecting part of the needle head is positioned in the explosion-proof ball.
In one embodiment, the sample tube is a U-shaped tube.
In another embodiment, the sample tube is a 5mL U-shaped sample tube.
In one scheme, two foldable skirt edges of the flanging plug seal the sample tube and the explosion-proof ball.
In one scheme, the flanging plug is a flanging plug synthesized by natural rubber materials with acid-base resistance, organic solvent resistance and temperature resistance.
In one scheme, the needle head is connected with a sample tube and an explosion-proof ball which are separated by a flanging plug.
The utility model has the advantages that:
the utility model discloses a desolventizing device is improved to nitrogenous class compound technology can conveniently handle the desolventizing of the nitrogenous class compound sample of milligram level or milli upgrading, can not influence the quality of sample, the processing and the taking out of the sample of being convenient for.

FIG. 2 is an exploded view of an assembly of the present invention;
in the figure, 1-sample tube, 2-needle, 3-turnover plug and 4-explosion-proof ball.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in the figure, the improved desolventizing device for the process of the nitrogenous compound comprises a sample tube 1, a needle head 2, a turnover plug 3 and an explosion-proof ball 4. Wherein the flanging plug 3 is also called a flanging rubber plug and is synthesized by acid-base-resistant organic solvent-resistant and temperature-resistant natural rubber materials. The sample tube 1 is a 5mL U-shaped sample tube, which can be made of glass or plastic.
One end of the flanging plug 3 is connected with the opening of the sample tube 1, the other end of the flanging plug 3 is connected with the gas inlet of the explosion-proof ball 4, two foldable skirt edges of the flanging plug 3 are respectively wrapped on the outer walls of the opening of the sample tube and the gas inlet of the explosion-proof ball, and the two foldable skirt edges seal the sample tube 1 and the explosion-proof ball 4.
The needle head 2 is inserted on the plug cover of the turnover plug 3, the needle tip part of the needle head is positioned in the sample tube 1, and the connecting part of the needle head is positioned in the explosion-proof ball 4. The needle is connected with a sample tube 1 and an explosion-proof ball 4 which are isolated by a turnover plug 3.
When the device is used, a nitrogen-containing compound micro-sample dissolved in an organic solvent is firstly loaded into the sample tube 1, and then the sample tube 1 is connected with the flanging plug 3 and sealed by the foldable skirt. The top connecting end of the explosion-proof ball 4 in the device is connected to a rotary evaporator, the height and the position of the water bath or the oil bath are adjusted to enable a part of the sample tube 1 to be positioned in the water bath or the oil bath, and desolventizing treatment is carried out. The desolventized sample is located in the sample tube and can be conveniently collected or directly stored in the sample tube.
