Atmospheric pressure:Determinations1and 2:  100.2 kPa,Determinations3 to 8:  100.0 kPa

Determinations 1 and 2 were used as a preliminary assessment. Further determinations (Determinations 3 to 8) were used to concentrate on specific areas of interest. Analysis of the thermograms combined with the weight loss of the residue established that the test item lost volatiles between 60 and 300 °C (333 to 573 K), the test item then decomposed from approximately 330 °C (603 K). As the test item decomposed, no value for boiling point could be determined. 

 

Overall result:The test item lost volatiles between ambient and 300 °C (298to573 K),andthen decomposed from approximately 330 °C (603 K)at100 kPa. As the test item decomposed, no value for boiling point could be determined.

Conclusions:

The test item lost volatiles between 60 and 300 °C (333 to 573 K), and then decomposed from approximately 330 °C (603 K), at 100 kPa. As the test item decomposed, no value for boiling point could be determined.

Executive summary:

The general physico-chemical properties of μ(5-amino-1,3,3-trimethylcyclohexylamine-N,N')hexafluorodiboron have been determined. 

BoilingPoint.The test item showed theloss ofvolatiles between60and 300 °C (333– 573 K),and thendecomposed from approximately 330 °C (603 K)at 100 kPa. As the test item decomposed, no value for boiling point could be determined. The procedure used was designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

330 °C

Additional information

Decomposition started to occur at 330 degC and therefore boiling point could not be determined
