- Conclusions:
- Boiling point of DOTG can not be determinated since the product is decomposed at T > 195°C
- Executive summary:
A study was performed in to investigate the boiling point of the test substance DOTG (1,3 - di-o-tolylguanidine) and was conducted according to OECD Test Guideline 103.
The boiling point of DOTG can not be determinated since the product is decomposed at T > 195°C
Reference
Description of key information
decomposition of DOTG at T > 195°C
Key value for chemical safety assessment
- Temperature of decomposition (state purity):
- 195 °C
Additional information
According to three QSARs analysis and based on the chemical structure, the boiling point of DOTG (1,3 -di-o-tolylguanidine) will be in the range in the range 297 -402°C. these values are calculated without taking into account any decomposition.
Nevertheless, the product is not stable and according to two studies made with OECD 103, the product is decomposed at T > 195°C.
