Description of key information

Flash point (trimethoxyphenylsilane): 50°C to 94.3°C (closed cup)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
50 °C

Additional information

In a reliable study Dow Corning (1998) determined the flash point by Pensky-Martens closed cup method (ISO 2719:2002) to be 94.3°C. Wacker (2012) measured a flash point of 50°C in a reliable guideline study (ISO 3679). Presumably the flash point decreases with an increase of the low boiling impurities, like methanol, a hydrolysis product of the substance.
