Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From December 1 to 12, 2008
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised with its purity. Validation applies, with minor restrictions due to heating rate.

Principles of method if other than guideline:
Not applicable
GLP compliance:
yes (incl. certificate)
Remarks:
Swiss GLP compliance programme (inspected on November 15 and 16, 2006 / signed on March 29, 2007)
Type of method:
method according to Siwoloboff
Specific details on test material used for the study:
Storage condition of test material: Refrigerator (between 0 and 10 °C under nitrogen)
Key result
Boiling pt.:
267 °C
Atm. press.:
95.4 kPa

Preliminary test: 548 K (275 °C) at 95.4 kPa

Determination 1: 540 K (267 °C) at 95.4 kPa

Determination 2: 540 K (267 °C) at 95.4 kPa

Executive summary:

The boiling point of the test substance was determined under GLP according to OECD 103/EU A2 guideline, Siwoloboff (capillary) method. Two main runs were performed, and the mean final temperature was retained.

The boiling temperature of test substance has been determined to be 267 ± 1 °C (540 ± 1 K) at an atmospheric pressure of 95.4 kPa.

Description of key information

Measured boiling point = 267°C under 95.4 kPa. (not corrected to normal atmP)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
267 °C

Additional information

A reliable experimental study, conducted according to a recognized OECD/EU method and under GLP, is available. Despite minor restrictions due to technical inaccuracy, it is considered as a key study. The result is retained as key data.
