Determination of the Boiling Point
The purpose of this study was to evaluate the boiling
point of (2Z)-2-Fluor-3-(morpholin-4-yl)acrylaldehyd (FMA) by the
capillary method using an electronic controlled heating system.
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
The determination of the boiling point was performed by
visual judgement using the capillary. At about 200 °C to 265 in the
preliminary tests, the colour changing to black was observed and the
test item melted. To confirm the results from the preliminary tests, the
test was performed three times with the new sample and with the heating
rate of 0.5 °C/min; start temperatures were: 215 °C, 220 °C and 225 °C
and end temperature was 265°C. Due to this observation, a decomposition
process at approximately 220 °C is assumed. A clear normal boiling
point, as defined in the guideline with a current stream of bubbles
evolving from the capillary, was not observed.
Conclusion: In conclusion, for
(2Z)-2-Fluor-3-(morpholin-4-yl)acrylaldehyd (FMA) no boiling point
according to the criteria described in the guideline could be observed
up to 400 °C. The atmospheric pressure was 99.08 kPa. This
study is classified acceptable and satisfies the guideline requirements
for boiling point studies.
