EC number: 939-512-2
CAS number: 85681-55-6
Expt 1: Two small endothermic effects were observed: between 35°C and
67°C and between 67°C and 130°C. An exothermic effect started at about
175°C, probably caused by reaction or decomposition of the test
substance. After the experiment, the sample had a light-yellow colour
(original colour: white). The sample appearred to have not been molten,
but the particles had coalesced. Weighing showed that the sample had
lost 3% of its mass.
Expt 2: A small endothermic effect was observed between 35°C and 60°C.
The DSC-curve recorded during the second run of the second experiment
(25°C - 65°C) showed no heat effect. After the experiment, the
consistency of the sample had not changed. The sample had lost 1% of its
mass. It is very likely that the endothermic effect was caused by
evaporation of a small part of the test substance, possibly volatile
Expt 3: Two small endothermic effects were observed: between 35°C and
61°C and between 61°C and 122°C. The DSC-curve that was recorded during
the second run of the third experiment (25°C - 155°C) showed three small
endothermic effects: between 48°C and 67°C, between 67°C and 82°C and
between 93°C and 132°C. After the experiment the sample appeared not to
have been molten, but the particles coalesced. The colour of the sample
had not changed. The sample had lost 1% of its mass.
Expt 4: Two (small) endothermic effects were observed: between 38°C and
63°C and between 63°C and 125°C. An exothermic effect started at about
163°C, probably caused by reaction or decomposition of the test
substance. After the experiment, the sample had a light-yellow colour.
The sample appeared to have not been molten, but the particles had
coalesced. The sample had lost 1% of its mass.
In a melting/boiling point study performed in accordance with EC Method
A1 and OECD Guideline No 102 using Differential Scanning Calorimetry
(DSC) no melting or boiling temperature could be determined for the test
material. Reaction or decomposition started at 163°C - 175°C.
The substance decomposes without melting starting at 163°C - 175°C.
