In accordance with the oOECD Guideline 102,
determination of the melting point of DTPA-MnNa3(MnDTPA)
was carried out.
The capillary tube in heated metal
block method and BÜCHI Melting Point B-565 apparatus was used. For
melting point determination a substance sample was finely ground, placed
in a capillary tube and packed tightly. The measurements were performed
in three parallel tubes. Observations of the tested material properties
changes were recorded in the temperature range investigated.
The preliminary study and
measurements were performed under atmospheric pressure of 999.7 hPa.
The study was carried out in order to determine the melting
temperature range for DTPA-MnNa3(MnDTPA)
(50.0 – 400.0°C).
In final test the three series of
boiling point measurements were performed in the temperature range
290.0 - 400.0 °C. The heating rate was 0.5°C/min. In all samples
was observed change the tint from beige to brown and
characteristic smell indicating the thermal decomposition of the sample.
The average value of initial decomposition temperature for the three samples of
is 294.25 ± 0.76 °C.
decomposes below melting and boiling point under atmospheric pressure of
999.7 hPa at 294.25 ± 0.76 °C (the average value). (Methods: EEC A.1 and
OECD No. 102; EEC A.2 and OECD No.103).
