yes (incl. QA statement)

Type of method:

differential scanning calorimetry

Specific details on test material used for the study:

Sponsor's identification: Amine C8
Description: dark brown liquid
Batch number: T7-271109
Date received: 21 September 2010
Expiry date: 31 December 2011
Storage conditions: room temperature in the dark

Key result

Boiling pt.:

>= 223 - <= 383 °C

Atm. press.:

101.04 kPa

Decomposition:

no

Remarks on result:

other: Partial boiling from 223 to 383°C. A dark brown residual stain remained in the crucible, most likely due to non-volatile components in test item.

Thermograms and thermographic data for determinations 1 and 2 are shown in Attachments and in the tables below

Thermographic Data Determination 1

Thermal Event	Interpretation	Temperature
		ºC	K
Broad endotherm	Partial boiling	223 to 382	497 to 655

Atmospheric pressure: 101.04 kPa

Thermographic Data Determination 2

Thermal Event		Interpretation		Temperature
			ºC		K
Broad endotherm		Partial boiling		224 to 383		498 to 656

Atmospheric pressure: 101.04 kPa

Overall result:

The test item was considered to partially boil from 223 to 383ºC (497 to 656 K), leaving a dark brown residual stain in the crucible possibly due to non-volatile components in the test item. 

Conclusions:

The test item was determined to partially boil from approximately 223 to 382ºC (497 to 655 K) at 101.04 kPa.

Executive summary:

The test item was determined to partially boil from approximately 223 to 383ºC (497 to 656 K) at 101.04 kPa, by differential scanning calorimetry, using ASTM E537-86, designed to be compatible with Method A2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Description of key information

The test substance was determined to partially boil from 223 to 383ºC at 101.04 kPa, by differential scanning calorimetry, using ASTM E537-86, designed to be compatible with EC test method A.2, under GLP conditions (Butler and White, 2010).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

223 °C

Additional information

No fixed boiling temperature is obtained; the onset of the boiling range is proposed for use in the CSA.
