This Automatic Reaction Calorimeter 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 Automatic Reaction Calorimeter 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.
