A method for determining the thermal hazards of reactive chemicals using DSC measurement! Glass vials are the sample containers.
This document is a technical note explaining the determination of SADT (Self-Accelerating Decomposition Temperature) using a small-scale reaction calorimeter with a mL size (glass vial). We attempted SADT simulation using azobisisobutyronitrile (AIBN) to determine the thermal hazards of reactive chemicals through DSC measurements. In this note, we used a mL size small-scale reaction calorimeter, with a heating rate of 0.025 to 0.20 K/min, which is approximately 1/20 of the typical DSC measurement range of 0.5 to 8 K/min. We encourage you to read it. [Published Data (Excerpt)] - DSC data for 1 mg of AIBN (azobisisobutyronitrile) at 5 K/min - Heating rate of 0.025 K/min - Heating rate of 0.050 K/min - Heating rate of 0.20 K/min - Predictions of what kind of DSC measurement data can be obtained *For more details, please download the PDF or feel free to contact us.

Company information
Our company works in the field of thermal safety evaluation to prevent thermal runaway accidents involving chemical substances. To achieve this, we analyze reaction kinetics parameters from thermal measurement data of a few milligrams of chemical substances and provide a measurement and analysis system that enables thermal safety evaluation when the chemical substances are scaled up to kg to 1000 kg. Additionally, we offer an evaluation system that combines isothermal microcalorimeters (IMC) for lithium-ion batteries and DSC with AKTS analysis software, allowing for comprehensive measurement of the entire battery.
