Thermographic Data – Determination 1

 

Thermal Event	Interpretation	Temperature
		ºC	K
Endotherm	Melting	21.3 to 33.2	294 to 306

Thermographic Data – Determination 2

 

Thermal Event	Interpretation	Temperature
		ºC	K
Endotherm	Melting	21.4 to 32.9	295 to 306

Overall melting range: 21.3 to 33.2 °C (294 to 306K)

Discussion:

The test item melting took place over a significant temperature range, resulting in a broad endotherm on the thermograms. Therefore, a temperature range was considered more appropriate as the overall result.

Conclusions:

Under the study conditions, the melting range of the test substance was determined to be 21.3 to 33.2 °C (294 to 306 K).

Executive summary:

A study was conducted to determine the glass transition temperature of the test substance, trichloro(N,N-dimethyloctylamine)boron using differential scanning calorimetry according to OECD Guideline 102 and EU Method A.1 in compliance with GLP. Aliquots of test item were placed in aluminum crucibles. The crucibles were subjected to a thermal program from 5 °C to 50 °C at 20 °C/min. The appearance of the samples (residue) was recorded after the test. Under the study conditions, the melting range of the test substance was determined to be 21.3 to 33.2 °C (294 to 306 K) (Harlan, 2014).

Description of key information

The melting point was determined accordng to differential scanning calorimetry method based on OECD Guideline 102 and EU Method A.1. (Harlan, 2014).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:

21.3 °C

Additional information

The melting range of the test substance was determined to be 21.3 to 33.2°C.
