Abstract
The utility model discloses an organic solvent concentration real-time determining device in reaction, comprising a sampling container, a light source and a light intensity tester, wherein the sampling container is communicated with a reaction tank, the light source is positioned at one side of the sampling container and has solution characteristic wavelength, and the light intensity tester is used for measuring the light intensity difference at two sides of the sampling container. Therefore, since the sampling container communicated with the reaction tank is adopted, the steps of sampling from the reaction tank by a cuvette and pouring the sampled solution into the reaction tank can be saved, the device not only can obtain the concentration numerical value of the solution in real time, but also can not influence the reaction progress, and the data is continuous.
Description
Technical field
The utility model relates to organic solvent concentration determination technical field in the reaction, more particularly, relates to organic solvent concentration The real time measure device in a kind of reaction.
Background technology
At present, in experimentation, measuring the testing tool that organic solution concentration is adopted in the reaction is spectrophotometer.Specific practice is that measurement organic solution absorbance then selects this organic solution to demarcate at the absorbance numerical value of characteristic wave strong point with wavelength change earlier.
There is following some deficiency in this mode:
1, efficient is low
Since be artificially at interval certain hour from reaction tank, take out sample and pack into behind the cuvette, delivers to again and carry out length scanning in the spectrophotometer, so measuring speed is very slow.
2, the progress of influence reaction
Solution after test finishes in the cuvette must be poured reaction tank again into, has therefore influenced normally carrying out of reaction.
3, test data is discontinuous
Finish to measurement and draw data from taking out sample, again to sample is poured into the time that reaction tank needs a few minutes, so the tester can not see the variation that solution concentration is in good time.
The utility model content
Technical problem to be solved in the utility model is to provide organic solvent concentration The real time measure device in a kind of reaction, and it can obtain continuous test data apace, and does not influence the progress of reaction.
For solving the problems of the technologies described above, the technical solution of the utility model is: organic solvent concentration The real time measure device in a kind of reaction is provided, comprise the sampling container that is communicated with reaction tank, be positioned at described sampling container one side and have described solution characteristic wavelength light source, measure the light intensity test instrument of described sampling container both sides light intensity difference.
More specifically, described sampling container and described reaction tank form closed circuit by pipeline.
More specifically, described closed circuit is provided with ebullator.
More specifically, described light source is a led light source.
Like this owing to adopt the sampling container be communicated with reaction tank, the Therefore, omited employing cuvette from reaction tank, take a sample, and the solution of will taking a sample is poured the step of reaction tank into, not only can obtain the concentration numerical value of solution in real time, also can not influence the progress of reaction, and data also be continuous.
Description of drawings
Fig. 1 is the principle of work synoptic diagram of the utility model one preferred embodiment;
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 1, be a preferred embodiment of organic solvent concentration The real time measure device in the utility model reaction, this determinator comprises the sampling container 2 that is communicated with reaction tank 1, be positioned at described sampling container 2 one sides and have the described solution characteristic wavelength (wavelength X of ie in solution during to the light absorption maximum
Max) light source 3, measure the light intensity test instrument 4 of described sampling container 2 both sides light intensity difference.Like this, owing to adopt the sampling container 2 that is communicated with reaction tank 1, the Therefore, omited prior art adopt cuvette from reaction tank 1, to take a sample, and the solution of will taking a sample is poured the step of reaction tank 1 into, not only can obtain the concentration numerical value of solution in real time, also can not influence the progress of reaction, and data also are continuous.
In the present embodiment, in order to quicken the circulation of solution between sampling container 2 and the reaction tank 1, with the uniform relatively reaction solution of acquisition concentration, and then make test result more accurate, described sampling container 2 and described reaction tank 1 form closed circuit by pipeline.In order to quicken organic solvent, on described closed circuit, also be provided with ebullator 5 the flowing of described closed circuit.And, by the duty of Control Circulation pump 5, can make the organic solvent in the closed circuit have different flow velocitys.
Described light source 3 is LED (Light Emitting Diode; Light emitting diode) light source, this be because.Led light source has the narrower characteristics of wave amplitude, and different led light sources has different wavelength, can corresponding different organic solvents.Therefore can select different led light sources for use at different organic solvents, this has also omitted needs to measure earlier the step of organic solution absorbance with wavelength change in the prior art.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
