The world's first shared database on the thermal stability of chemicals has been established

The database is under development (aiming to build the world's first shared database of chemical thermal stability, currently 1500 chemical tests have been completed), and the first phase (2024-2025) plans to complete the thermal stability experimental tests of 2828 hazardous chemicals in the National List of Hazardous Chemicals (2018 edition). The center shares the starting temperature and total decomposition energy of these experimental tests free of charge at home and abroad (please refer to the English page for the English report), and the complete experimental report requires member points in exchange (DSC test report examples, including sample details, DSC spectra, reaction kinetics that can be further derived from the spectra). Members' points can be purchased directly (to support post-testing) or in exchange for providing the site with non-repetitive response incident data (which will be available after phase 1 is completed).

 Please note: The data contained in the RCSC experimental test database is obtained based on the specific samples of a supplier. During the test process, we have tried our best to ensure the reliability of the data, but we still do not exclude the data differences introduced by supplier differences, sample impurities, long-term storage deterioration, test method errors, human errors, etc.Therefore, we recommend only using RCSC experimental test data as a reference.We are not liable for any loss arising from any reason.

Remark：

1. The DSC test conditions of this database refer to ASTM E537-24. The test parameters of most DSC experiments are glass capillary crucible, 0~400℃, 10℃/min, repeated twice, the headspace is nitrogen, and the sample leakage is less than 5% (test parameters are subject to the experiment report).

2. The Center discloses two key parameters free of charge: initial temperature and total energy. The starting temperature can help judge the possibility of decomposition reaction of the chemical in a certain process (except storage) (when the maximum temperature of the normal process or the temperature of the hot medium is lower than the starting temperature of DSC by 100℃, the probability of the decomposition reaction causing a safety accident is low; When high, it is recommended to do more specific reaction safety risk analysis; The self-catalytic strength of the decomposition reaction needs to be analyzed in the storage condition, which is not consistent with the simple method of 100℃); The total energy can help to determine roughly how dangerous the decomposition reaction is when it occurs (especially if the total energy of the chemical explosion is greater than 1000J/g)chemicals，According to the total mass, the damage range of the explosion can be quickly calculated).
