This testing device structure is simple, and sensitivity is compared with reliable degree and is but improved greatly in ordinary thermometer.
Description
Technical field
The utility model relates to a kind of experimental provision measuring solution chemistry reaction real-time temperature under room temperature, belongs to scientific experiment studying technological domain.
Background technology
Neutralization reaction in chemical reaction usually adopt titrimetry to determine time point is completely carried out in reaction, use the temperature difference before and after alcohol thermometer assaying reaction, therefore experiment also exists larger error simultaneously.Simultaneously strong acid (example hydrochloric acid, nitric acid etc.) and highly basic (as NaOH etc.) also can corrosion reaction containers, cause experimental provision serviceable life not freely, poor stability.
Summary of the invention
Goal of the invention: in order to overcome above-mentioned the deficiencies in the prior art, the object of the invention is to a kind of experimental provision measuring the real-time temperature change carrying out chemical reaction under room temperature between solution.
Technical scheme: a kind of experimental provision measuring solution chemistry reaction real-time temperature under room temperature provided by the invention, comprises feeding device, reaction unit, temperature measuring equipment; Porous ceramics thermal insulation board, Ta that described reaction unit comprises rustless steel container, coordinates with rustless steel container
2alC crucible, described rustless steel container and Ta
2aerogel is filled with between AlC crucible; Described temperature measuring equipment comprise be connected to each other with Ta
2the thermopair of AlC protective sleeve and smart temperature display; Described feeding device and thermopair pass porous ceramics thermal insulation board and are fixed on Ta
2in AlC crucible.
As improvement, described feeding device is the graduated syringe of band.
Improve as another kind, described porous ceramics thermal insulation board is the thermal insulation board of mullite fiber material.
Beneficial effect: experimental provision structure provided by the invention is simple, and sensitivity and fiduciary level but improve greatly compared to common thermometer.
Specifically, relative to prior art, there is following outstanding advantage:
(1) the utility model has selected the Ta with excellent heat conducting performance
2alC is as temperature sensor protecting cover, and the sensitivity that can not affect thermopair but adds decay resistance, Ta
2alC is compared to other common thermocouple protective sleeves (SiO
2protective cover for thermocouple is hydrofluoric acid resistant not, Al
2o
3protective cover for thermocouple is acid and alkali-resistance not) there is excellent heat conducting performance, very sensitive to the change of temperature, compared with common thermocouple, with Ta
2alC is that the thermopair of protective sleeve has resistance to strong acid (example hydrochloric acid, nitric acid etc.) and highly basic (as the NaOH etc.) performance of corroding, stability and the reliability of the utility model long-term work under very harsh environment can be ensured, make measured data more accurately credible;
(2) the utility model adopt temperature measuring equipment comprise be connected to each other with Ta
2the thermopair of AlC protective sleeve and smart temperature display, smart temperature display can record the change of this temperature of reaction, simultaneously owing to setting the time interval of data record, complete required time can also be carried out by open-and-shut knowing reaction, the severe degree of reacting and carrying out can also be inferred;
(3) consumption of reactant liquor when apparatus of the present invention can allow researcher or Students in Teaching understand the essence of neutralization reaction heat better and determine more accurately to react completely, the fields such as R&D units, ordinary higher learning school's teaching, middle school teaching that are adapted at are promoted.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention measures the experimental provision of solution chemistry reaction real-time temperature under room temperature.
Embodiment
Below in conjunction with accompanying drawing the present invention made and further illustrating.
Under measurement room temperature, the experimental provision of solution chemistry reaction real-time temperature, is shown in Fig. 1, comprises feeding device 1, reaction unit 2, temperature measuring equipment 3; Porous ceramics thermal insulation board 5, Ta that reaction unit 2 comprises rustless steel container 4, coordinates with rustless steel container 4
2alC crucible 6, rustless steel container 4 and Ta
2aerogel 7 is filled with between AlC crucible 6; Temperature measuring equipment 3 comprise be connected to each other with Ta
2the thermopair 8 of AlC protective sleeve and smart temperature display 9; Feeding device 1 and thermopair 4 pass porous ceramics thermal insulation board 5 and are fixed on Ta
2in AlC crucible 6.Feeding device 1 is the graduated syringe of band.Porous ceramics thermal insulation board 5 is the thermal insulation board of mullite fiber material.
Principle of work: under apparatus of the present invention being put into the stationary temperature condition needed for experiment; Open sensitive thermometer switch and set the time interval of recording temperature, such as, with 10
-3second, 10
-2second, 10
-1second, within 1 second, 10 seconds, record and storing temperature data for the time interval, and " temperature---time " change curve can be drawn with this data post; In device to be injected solution temperature consistent with environment after again by syringe solution inject reaction vessel can obtain experimental data.
Concrete, when measuring neutralization reaction heat and completeness is carried out in titration measuring reaction, feeding device is two.
When measuring the experiment of neutralization reaction heat: be filled with strong acid solution and strong base solution respectively in feeding device, open separating funnel knob simultaneously and flow down smoothly by solution; Sensitive thermometer can record the change of this hybrid reaction temperature, simultaneously owing to setting the time interval of data record, can also carry out complete required time by open-and-shut knowing reaction, namely can infer the severe degree of reacting and carrying out.
With titration measuring reaction carry out completeness determine time: two feeding devices are equipped with two kinds of reaction solutions respectively, now a feeding device is opened, wherein solution is flowed down smoothly, finely tuning another feeding device switch again makes dropwise drip, because sensitivity of the present utility model is high, can change according to except reacting the color self had or except precipitation generation, the end of a period point of reaction can also be determined according to the situation of change of temperature of reaction.
