Adiabatic Calorimeters: Utilizing Heat Transfer in Controlled Environments
The adiabatic calorimeter is a professional instrument used for testing the heat of explosion of compounds and the reaction heats and thermal runaway processes between the components of metastable materials. By maintaining the environmental temperature equal to the reaction system temperature, it measures the heat behavior of the sample under adiabatic conditions, obtaining thermodynamic and kinetic data of the chemical reaction process in adiabatic state, and inferring important parameters such as TD24, TMRad, and SADT. The adiabatic calorimeter is mainly used in the fields of compound product processes and safety control, and it analyzes the thermokinetic data and thermal runaway processes of the reaction.
Applications of adiabatic calorimeters
Adiabatic kinetic analysis of nitrating products
The TAC-500AE adiabatic accelerating calorimeter integrates various reaction kinetic analysis methods. In situations where the reaction mechanism model is unclear, to avoid errors caused by mismatched preset models, the conversion rate method can be selected for parameter fitting. For reactions with a clear n-level reaction kinetic equation, the rate constant method can be directly used for fitting.

Cleaning Tips
Sample chamber cleaning
After completing the experimental test, raise the furnace cover and connect the air compressor to the instrument’s cooling hole to quickly cool the instrument to a safe temperature. Open the pressure relief valve to release high-pressure gas. Using the provided wrench, remove the sample chamber, pour the liquid or solid samples or products into the waste liquid tank, and clean the sample chamber with alcohol or other organic solvents. If conditions allow, use an ultrasonic cleaning machine to prevent cross-contamination between experiments.
Pipeline and joint cleaning
The instrument is equipped with two sets of exhaust pipelines. After each experiment, dismantle the pipelines used in the experiment and replace them with backup pipelines to continue the experiment, thereby improving the overall efficiency of the experiment. Clean the disconnected pipelines with an organic solvent that is mutually soluble with the experimental sample and air dry. If conditions allow, use an ultrasonic cleaning machine.
Furnace cleaning
If there are incidents such as sample chamber explosion, sample overflow during the sample chamber loading and unloading process, please clean the furnace in a timely manner to prevent the furnace from being exposed to corrosive liquids for a long time, which may damage the furnace’s thermocouple.
