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.

Standards

(1)GB 51283-2020: Fire Protection Standard for Engineering Design of Fine Chemical Enterprises

(2)GB/T 22232-2008: Determination of Thermal Stability of Chemical Substances - Differential Scanning Calorimetry

(3)GB/T 17802-2011: Thermal Analysis Test Method for Kinetic Constants of Thermally Unstable Substances

(4)SN/T 3078.1-2012: Guidelines for the Evaluation of Thermal Stability of Chemicals - Part 1: Accelerated Calorimetry

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.
