Results and discussion
Boiling point
- Key result
- Boiling pt.:
- 259 °C
- Atm. press.:
- 101.3 kPa
Any other information on results incl. tables
The determination of the boiling point was performed by visual judgement using the capillary.
At about 268.5 °C in the preliminary tests, the number of air bubbles increased. To confirm the result obtained in the preliminary tests, the determination of the boiling point was performed three times, heating quickly up to 350 °C and afterwards slowly using a heating rate of 0.5 °C/min.
A clear normal boiling point, as defined in the guideline with a current stream of bubbles evolving from the capillary, was observed at a heating temperature of 368.9 °C.
Applicant's summary and conclusion
- Conclusions:
- In conclusion, using the capillary method according to EU A.2, OECD 103, OPPTS 830.722 the test item Fluorpyridonitril started boiling at 368.9 °C (642.0 K) at normal pressure (101.325 kPa).
- Executive summary:
Title:Fluorpyridonitril: Determination of the Boiling Point
Purpose:
The purpose of this study was to evaluate the boiling point of
Fluorpyridonitril by the capillary method using an electronic controlled heating system.
Guidelines/Recommendations:
This study was based on the procedures indicated by the following internationally accepted methods:
Commission Regulation (EC) No.440/2008 laying down test methods pursuant to Regulation (EC) No.1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) (originally published as Council Regulation (EC) No.440/2008, corrigendum according to Official Journal of the European Union (EN) dated June 3, 2008, L 143/55), Annex, Part A, A.2.: “Boiling Temperature”, Official Journal of the European Union, L 142, Volume 51, 31 May 2008
Organization for Economic Co-operation and Development (OECD), Guidelines for Testing of Chemicals, Guideline No.103, “Boiling Point”, adopted July 27, 1995
Product Properties Test Guideline OPPTS 830.7220 of the United States Environment Protection Agency (EPA), August 1996
Results:
The determination of the boiling point was performed by visual judgement using the capillary.
At about 268.5 °C in the preliminary tests, the number of air bubbles increased. To confirm the result obtained in the preliminary tests, the determination of the boiling point was performed three times, heating quickly up to 350 °C and afterwards slowly using a heating rate of 0.5 °C/min.
A clear normal boiling point, as defined in the guideline with a current stream of bubbles evolving from the capillary, was observed at a heating temperature of 368.9 °C.
Conclusion: In conclusion, using the capillary method according to EU A.2, OECD 103, OPPTS 830.722 the test item Fluorpyridonitril started boiling at 368.9 °C (642.0 K) at normal pressure (101.325 kPa).
This study is classified acceptable and satisfies the guideline requirements for boiling point studies.
