Interpretation of results:
GHS criteria not met
Conclusions:
No signs of an explosive reaction could be observed in any of the tests.
In the test for thermal sensitivity, the test item evaporated through the orifice and burned (duration 1:27 – 1:35 minutes), but no explosion was observed.
Therefore, the test item "2-propanol and 2-butanol production, distn. residues" is considered as “not explosive under the conditions of guideline EU A.14”.
Executive summary:

The explosive properties of "2-propanol and 2-butanol production, distn. residues" were determined following EU A.14.

In the test for thermal sensitivity, no explosion was observed.

In the test for mechanical sensitivity (shock), no explosion was observed when using a force of 40 J.

The test for mechanical sensitivity (friction) was not performed due to the liquid nature of the test item.

The test item “2-propanol and 2-butanol production, distn. residues” can be considered as “not explosive under the conditions of guideline EU A.14”.

Description of key information

The explosive properties of “2-propanol and 2-butanol production, distn. residues” were determined following EU A.14.

In the test for thermal sensitivity, no explosion was observed.

In the test for mechanical sensitivity (shock), no explosion was observed when using a force of 40 J.

The test for mechanical sensitivity (friction) was not performed due to the liquid nature of the test item.

The test item “2-propanol and 2-butanol production, distn. residues” can be considered as “not explosive under the conditions of guideline EU A.14”.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The tests performed under GLP and according to the Guidance EU A.14 were negative, indicating that “2-propanol and 2-butanol production, distn. residues” is not explosive.

Justification for classification or non-classification

The tests performed under GLP and according to the Guidance EU A.14 were negative, indicating that the test item is not explosive.

However, “2-propanol and 2-butanol production, distn. residues” is containing ca. 30 - 50% di-isopropyl ether (CAS 108-20-3) which may form explosive peroxides. According to the work experience with “2-propanol and 2-butanol production, distn. residues” and the official classification of DIPE, this substance should be classified with EUH019.
