Results and discussion

Applicant's summary and conclusion

Conclusions:
Reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) should be classified as EUH019, may form explosive peroxides.
Executive summary:

Reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) is containing ca. 30% diisopropyl ether (CAS 108-20-3) which may form explosive peroxides. According to the work experience with reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) and the official classification of DIPE, this substance should be classified with EUH019.
