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.
Utility model content
Utility model object: in order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model measures the experimental provision of the real-time temperature change carrying out chemical reaction between solution under there are provided a kind of High Temperature High Pressure, the composition of the utility model experimental provision is very simple, principle is easy understand also, but sensitivity and fiduciary level but improve greatly compared to common thermometer, and the sealing property of excellence and decay resistance make the utility model be applicable to the chemical reaction of complicated condition harshness.
Technical scheme: a kind of experimental provision measuring solution chemistry reaction real-time temperature under high temperature and high pressure environment that the utility model provides, comprises feeding device, reaction unit, temperature measuring equipment and supercharging device; Stainless steel gland bonnet, Ta that described reaction unit comprises rustless steel container, coordinates with rustless steel container
2alC crucible, is provided with insulating rubber between described rustless steel container and stainless steel gland bonnet, described Ta
2alC crucible top is provided with porous ceramics thermal insulation board, 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 stainless steel gland bonnet and are fixed on Ta
2in AlC crucible; Described supercharging device and Ta
2alC crucible connects.
As improvement, described feeding device is the graduated syringe of band; Can accurate response liquor capacity situation, and the injection of solution in syringe can be entered in high-temperature high-voltage reaction container.
Beneficial effect: the experimental provision structure that the utility model provides is simple, with low cost, easy to use, and good stability, reliability is high.
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 originality adds a supercharging device, reaction pressure can be regulated to arrive required condition under, and
(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.
