CAS number: -
TGA EXPERIMENT (PRELIMINARY TEST)
From 325°C upwards the weight of the sample
decreased significantly. At 385°C the sample weight had decreased by
25%. After the experiment, a black brown molten residue remained in the
sample container. Residue was observed on the lid of the sample
container. The change of the colour indicated reaction and/or
decomposition of the test substance.
DSC EXPERIMENT 1
During cooling, a glass transition was
observed between -60°C and -80°C. During heating, a glass transition was
observed between -75°C and -50°C. The inflection point of the glass
transition was -61.76°C. From 225°C an exothermic followed by an
endothermic effect was observed. The effect was due to reaction and/or
decomposition of the test substance. After the experiment, a brown
residue remained in the sample container.
DSC EXPERIMENT 2
Similar results as with Experiment 1 were
obtained. The inflection point of the glass transition was -61.46°C.
After the experiment, a brown residue remained in the sample container.
DSC EXPERIMENT 3
To investigate if the test substance did
react during the glass transition the temperature program was stopped at
200°C. The inflection point of the glass transition was -61.64°C. After
the experiment the sample appeared to have been unchanged, i.e. no
decomposition and/or evaporation were observed.
The glass transition temperature of
the substance was calculated as the average from Experiment 1
(-61.76°C), Experiment 2 (-61.46°C) and Experiment 3 (-61.64°C): -62°C.
Differential Scanning Calorimetry experiments were performed in a GLP
study according to EC A.1, OECD 102 and OPPTS 830.7200. The substance
PEMP product is a liquid at room temperature. The substance has no
melting/freezing point in the range -90 to 25°C. From three experiments,
a mean glass transition temperature of -62°C was obtained. Reaction
and/or decomposition was observed at temperatures > 225°C.
No melting/freezing point in the range -90 to 25°C (EC A.1, OECD 102,
OPPTS 830.7200: DSC)
Glass transition temperature: -62°C.
The value of -20°C is the lower limit for melting/freezing point
determination according to Column 2 of Annex VII to REACH and was
therefore chosen as the key value for CSA.
