Key result
Boiling pt.:

Atm. press.:
> 990 - < 1 020 hPa

Preliminary test:

The test item was heated at a rate of 20°C/minutes from 17°C to 26°C. At this temperature, the test item lost 70% of his weight.

Main study:

5 experiments have been performed with the DSC apparatus.

An endothermik peak have been observed during 4 experiments. In one experiment, the quantity of sample used was too low to observed a clear peak.

2 experiments have been performed with a closed container with a lid possessing a small hole. In order to confirm the boiling temperature obtained, two ingestigations with a closed sample container have been performed.

An accurately measured boiling temperature was not possible. Therefore a boiling range was given. The boiling point was determined as the lowest and highest boiling temperature obtained from the experiments using a closed container with a small hole in the lid.

Conclusions:
The test item boiling is include between 18.84 °C and 23.29°C at 990-1020 hPa.
Executive summary:

The boiling point of the test item was determined with Differential Scanning Calorimetry (DSC) according to recognized guidelines (OECD Guideline 103,EU Method A.2 and EPA OPPTS 830.7220) and GLP.

No deviations from the guidelines have been observed during the test.

The boiling point range have been obtained based on two measurements performed between 900 and 1020 hPa.

The test item boiling is include between 18.84 °C and 23.29°C .

Description of key information

The boiling point of the test item was determined with Differential Scanning Calorimetry (DSC) according to recognized guidelines (OECD Guideline 103,EU Method A.2 and EPA OPPTS 830.7220) and GLP.

No deviations from the guidelines have been observed during the test.

Key value for chemical safety assessment
