Applicant's summary and conclusion
- Conclusions:
- The test item Triethylene glycol dimethanesulfonate (CAS no. 80322-82-3) in closed goldplated stainless-steel crucibles up to 500 °C showed four exothermic effects starting at temperatures of 100 °C, 160 °C, 310 °C and 370 °C, respectively, with average energy releases of -40 J/g, -920 J/g, -50 J/g and -120 J/g. In a closed glass crucible up to 300 °C the test item showed two exothermic effects starting at temperatures of 100 °C and 170 °C, respectively, with energy releases of -20 J/g and -920 J/g.
- Executive summary:
The test item Triethylene glycol dimethanesulfonate (CAS no. 80322-82-3) in closed goldplated stainless-steel crucibles up to 500 °C showed four exothermic effects starting at temperatures of 100 °C, 160 °C, 310 °C and 370 °C, respectively, with average energy releases of -40 J/g, -920 J/g, -50 J/g and -120 J/g. In a closed glass crucible up to 300 °C the test item showed two exothermic effects starting at temperatures of 100 °C and 170 °C, respectively, with energy releases of -20 J/g and -920 J/g.
Explosive Properties
Since the overall decomposition energy is above the threshold of -500 J/g, further tests on the explosive properties have to be performed.Self-Reactive Properties
Due to the fact that the decomposition energy of the exothermic effects is above -300 J/g and the onset started below a temperature of 200 °C, further tests on the self-reactive properties have to be performed.
