- Test procedure:
- step 2
- Max. rate of gas release:
- 0 L/kg min
- Identity of evolved gas:
- not applicable as no gas evolved
- Remarks on result:
- no reaction with water observed
- Interpretation of results:
- highly flammable
- Remarks:
- Migrated information
- Conclusions:
- The test item reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) is classified as not flammable in contact with water.
In accordance to the Technical Guidance on Information Requirements / CSA, section 7.1.10, the flammability of liquids is primarily defined by the flash point of the substance. According to the flash point and boiling point of reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA), the test item is highly flammable. - Executive summary:
Throughout the test for flammability in contact with water, the test item reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) showed negative results. The test item did not show any gas evolution at all.
Therefore, the test item reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) is classified as not flammable in contact with water.
In accordance to the Technical Guidance on Information Requirements / CSA, section 7.1.10, the flammability of liquids is primarily defined by the flash point of the substance. According to the flash point and boiling point of reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA), the test item is highly flammable.
Reference
The test item “2-propanol and 2-butanol production, distn. residues” is considered as not flammable in contact with water.
No gas evolution was observed throughout the experiment.
Description of key information
In accordance with Annex 1 to Regulation (EC) No 1272/2008, “2-propanol and 2-butanol production, distn. residues” is classified as highly flammable, H225.
Based on experimental results, the test item “2-propanol and 2-butanol production, distn. residues” is classified as not flammable in contact with water.
Key value for chemical safety assessment
