- Atm. press.:
- ca. 103 kPa
- Conclusions:
- The flash point of the test substance 3-Mercaptopropionsäure has been determined to be 124.5 °C (at pressure ~102.45 kPa).
- Executive summary:
The test material 3-Mercaptopropionsäure has been determined to have a flash point 124.5 °C (at pressure ~102.45 kPa) by using Pensky-Martens closed cup method according to method DIN EN ISO 2719:2002 (Determination of flash point - Pensky-Martens closed cup method).
Reference
Two determinations of of the flash point have been performed and the mean value of 124.5 °C has been reported (at pressure ~102.45 kPa).
Description of key information
Flash point: ca. 124.5 °C (at pressure ~102.45 kPa).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 123 °C
Additional information
The study performed in experimental laboratory (Petersen, 2004, UNA), dedicated to estimate the flash point of the test material 3 -Mercaptopropionsäure, has been chosen as a key study. The flash point has been determined to be 124.5 °C (mean value from two determinations at pressure ~102.45 kPa) by using Pensky-Martens closed cup method according to method DIN EN ISO 2719:2002 (Determination of flash point - Pensky-Martens closed cup method).
The other available supporting study (Rampy, 1973, Dow) reports the flash point to be greater than 98.33 °C. The information given in supporting study qualitatively supports the key study.
