The caffeine reference
standard had a reported melting point of 237 °C. The calibration
confirmation test resulted in a measured melting point of 237.0 °C. The
result was considered acceptable.
The benzophenone and
anthraquinone reference standards had reported melting ranges of 49 to
51 °C and 284 to 286 °C, respectively. Routine tests were conducted with
both reference standards on
the day of the definitive test with Phosflex 61B. The test using
benzophenone resulted in a measured
melting range of 49.1 to 49.8 °C. The test using anthraquinone resulted
in a measured melting
range of 284.5 to 285.6 °C. The results for both reference standards
were within the reported ranges, and the performance of the melting
point instrument was considered acceptable.
The first boiling
point/range approximation test resulted in a measured boiling point of
>400°C. The second
approximation test also resulted in a measured range of >400 °C. These
results were used to determine the range of temperatures used in the
A steady stream of bubbles
was not observed emerging from the boiling point capillaries at temperatures
up to 400 °C. All three subsamples of the test substance turned dark
amber upon reaching the end of the run. The maximum operating
temperature of the melting point instrument was 400
°C; therefore, the mean boiling point was determined to be >400 °C (>673
The boiling point of Phosflex 61B was determined using a Büchi
metlingpoint device according to OECD Guideline 102 and EPA OPPTS
820.7220 under GLP. The boiling point at 762 mm Hg was found to be > 400
degrees Celsius: samples turned dark amber .
The boiling point was determined to be >400 degrees Celsius at 762 mm Hg.
