Results and discussion

Boiling point

Decomposition:

ambiguous

Decomp. temp.:

ca. 399.5 °C

Remarks on result:

other: No boiling point as described in the guideline could be observed. At 399.5 °C the test item was light black. Due to this a decomposition process is suspected.

Any other information on results incl. tables

The determination of the boiling point was performed by visual judgement using the capillary method.

In the preliminary tests up to 400 °C the test item changed the colour from yellow to dark yellow/orange and melted. No boiling point as described in the guideline could be observed. At 399.5 °C the test item was light black. Due to this a decomposition process is suspected.

Applicant's summary and conclusion

Conclusions:

The Boiling point was determined in a GLP guideline study according to OECD 103, EU method A.2 and OPPTS 830.7220 without deviations on the registered substance itself. The capillary method according to Siwoloboff is a suitable method for boiling point determinations. Hence, there is no indication given that the results are not reliable.
In the preliminary tests up to 400 °C the test item changed the colour from yellow to dark yellow/orange and melted. No boiling point as described in the guideline could be observed. At 399.5 °C the test item was light black. Due to this a decomposition process is suspected.
In conclusion, for Octadecanoic acid, reaction products with tetraethylenepentamine no boiling point according to the criteria described in the guideline could be observed up to 400 °C.

Executive summary:

The determination of the boiling point of Octadecanoic acid, reaction products with tetraethylenepentamine was performed by visual judgement using the capillary method according to OECD 103, EU method A.2 and OPPTS 830.7220.

In the preliminary tests up to 400 °C the test item changed the colour from yellow to dark yellow/orange and melted. No boiling point as described in the guideline could be observed. At 399.5 °C the test item was light black. Due to this a decomposition process is suspected.

For Octadecanoic acid, reaction products with tetraethylenepentamine no boiling point according to the criteria described in the guideline could be observed up to 400 °C.
