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:
- 2011-10-24 till 2011-10-31
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Version / remarks:
- adopted 27 July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- dated 31 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Version / remarks:
- dated August 1996
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- > 400 °C
- Atm. press.:
- 1 013.25 hPa
- Remarks on result:
- other: No boiling point according to the criteria described in the guideline could be observed up to 400 °C.
- Conclusions:
- No boiling point according to the criteria described in the guideline could be observed up to 400 °C for potassium hexadecyl hydrogen phosphate.
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 method A.2, OECD TG 103 and OPPTS 830.7220 08.1996. The determination of the boiling point was performed by visual judgement using the capillary method according to Siwoloboff. In two preliminary tests up to 400 °C a change of appearance and consistency of the test item was observed, but a boiling point according to the criteria described in the guideline was not observed. An additional main test was performed in the temperature range from 230 °C up to 400 °C with a heating rate of 1 °C. At start temperature the test item was liquid. During the test the colour of the test item changed from colourless to milky white. No clear boiling point as described in the guideline could be observed.
