Automatic Reaction Calorimeter

This instrument is a professional testing instrument that simulates the specific process of chemical reactions on a liter scale, and measures and controls important process variables. It can simulate the real situation of batch or semi-batch reactions in a factory under laboratory conditions.

Applications

This instrument simulates real-world intermittent or semi-intermittent reactions in a factory, measuring the exothermic heat flow of samples within the reactor in real time. It obtains information on the total exothermic heat, specific exothermic heat, real-time conversion rate, and material accumulation, automatically calibrating the specific heat capacity and heat transfer coefficient of the material system. It then calculates the adiabatic temperature rise of the target reaction and the maximum temperature the system can reach after runaway, thereby assessing the hazard level of the reaction process and providing a basis for process optimization and scale-up. It is widely used in reaction process design, process optimization and scale-up, process safety assessment, and scientific research on reaction thermodynamics in fields such as fine chemicals, pharmaceuticals, agricultural fertilizers, and third-party safety assessment.

Features

1. It offers three calorimetry methods: heat - flow, power - compensation, and reflux, allowing users to choose according to their needs.

2. It supports multiple operation modes such as isothermal, constant - temperature, and scanning.

3. Optional glass normal - pressure reaction vessels, glass medium - pressure reaction vessels, and metal high - pressure reaction vessels are available.

4. It has an external database, and one system supports the interchange of multiple sets of reaction vessels.

5. With high - power heating and cooling units, it features fast temperature - control response and high - precision exothermic measurement.

6. Automatic feeding control can be achieved by mass or volume measurement.

7. It can accurately measure and obtain process - safety - related data such as reaction heat - flow, reaction enthalpy, conversion rate, specific heat capacity of samples, adiabatic temperature rise, and the maximum temperature that an out - of - control system can reach.

8. The Chinese - language software platform enables flexible programming of experimental procedures, real - time monitoring of key reaction - process data, and online modification of experimental procedures and parameters.

9. It can display the temperature inside the vessel, the temperature of the jacket, the mass of the added materials, and other test status information in real - time.

10. The safety thresholds for key parameters and states can be set. In case of reaction out - of - control, it can be quickly cooled with one click, and it will issue alarms and automatically stop in case of abnormal states, effectively ensuring safety.

11. It can automatically generate and save charts and data, and export experimental analysis reports.

Optional reactor types: Glass atmospheric pressure reactor, glass medium pressure reactor, metal high pressure reactor

Functional components: High-power heating/cooling unit, automatic feeding control unit (supports mass/volume measurement)

Auxiliary modules: External database module, Chinese experimental software platform

Test Procedures

1. Pre-Experiment Preparation

Select a suitable reactor (glass atmospheric/medium pressure or metal high pressure)

Install the stirrer, temperature sensor, and condenser

Connect the heating/cooling circulation system

Initialize the software and set experimental parameters (temperature, stirring rate, injection strategy)

2. Calibration Procedure

Heat Flow Method: Baseline measurement → Power calibration → Baseline recovery → Recalibration (obtain UA value)

Power Compensation Method: Set jacket temperature → Built-in heater compensates to maintain zero temperature difference → Directly measure compensated power

3. Reaction Testing

Add the base material and start stirring for preheating

Pre-reaction calibration (establish heat loss baseline)

Start the reaction (manual/automatic feeding), monitor temperature, pressure, and heat flow in real time

Post-reaction calibration (calculate total heat release)

Data Recording: Enthalpy change, adiabatic temperature rise, maximum reaction rate time (MTR)

4. Safety Precautions

High-pressure experiments must use a dedicated reactor (such as a Calvet reactor). (Type) Strongly exothermic reactions require safety interlocks and emergency cooling. Wear protective equipment; ensure good ventilation in the experimental area. Regularly check the oxygen bomb's seal (it is recommended to replace the sealing ring every six months).
