Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2002
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Study was carried out according to generally valid and internationally accepted testing guidelines and under GLP. Test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Version / remarks:
- 1995
- Deviations:
- yes
- Remarks:
- tested sample quantity was < 100 ml
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 1992
- Deviations:
- yes
- Remarks:
- tested sample quantity was < 100 ml
- Principles of method if other than guideline:
- not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspection date : 28/29 November 2002; validity : till 17 July 2004
- Type of method:
- distillation method
- Atm. press.:
- 936 hPa
- Decomposition:
- yes
- Decomp. temp.:
- > 250 °C
- Conclusions:
- Sodium Chlorate decomposes when liquified at 93.6 kPa (i.e. > 250°C).
- Executive summary:
The Boiling point of test item was determined according to EU method A.2. / OECD 103 guideline (using distillation method) and under GLP.
Sodium Chlorate decomposes when liquified at 93.6 kPa (i.e. > 250°C).
Therefore, no boiling point can be determined using this method.
Reference
Preliminary assay:
180 g of the test item were liquefied at approximately 275°C. The test item solidify in the round flask.
Thus, the test item was placed directly in the test flask and was melted (less than 100 ml was obtained). The liquid obtained was brown/red.
After 25 minutes of heating, the vapour temperature was approximately 135°C; the test was stopped because of solidification of the test item in the test flask.
No distillation range could be determined under the experimental conditions.
Description of key information
Decomposes > 250°C at 936 hPa
Key value for chemical safety assessment
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.
