Description of key information

The flash point of reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) was measured under GLP and according to the test guideline EU A.9. The mean of two independent determinations at standard pressure was - 4.5°C

Key value for chemical safety assessment

Flash point at 101 325 Pa:
-4.5 °C

Additional information

The flash point of reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) was measured under GLP and according to the test guideline EU A.9. The mean of two independent determinations at standard pressure was - 4.5°C.

Hence, the reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA is

classified with F, R11 (highly flammable) according to DPD or as Flam. liquid cat. 2, H225 (highly flammable liquid and vapor) according to the CLP regulation.
