- Executive summary:
The melting point of 2 -sec-butylphenol was determined using differential scanning calorimetry (DSC). The study followed OECD Guideline 102 (Melting Point/Melting range) and EU Method A.1 (Melting / Freezing Temperature). As a safety precaution for the DSC cell, a preliminary test was performed using a thermogravimetric analyzer (TGA). In the main study, three tests were performed. According to the DSC curves obtained, the melting temperature of the test substance was 10°C (283 K) at 101.1 kPa.
Reference
Preliminary test:
From 175°C upwards the weight of the sample decreased significantly. At 226°C the sample weight has decreased by 25%. After the experiment, there was no residue onserved in the sample container. The test substance had evaporated from the sample container.
Main study:
First experiment:
During cooling (not reported on detail), no effects were observed which were due to crystallization of the test substance. During heating, a glass transition at approximately -75 °C and an endothermic peak between 175 °C and 250°C was observed. The extrapolated onset temperature of the latter peak was 228.43°C. This effect was attributed to boiling of the test substance. After the experiment it was observed that the test substance has evaporated from the sample container.
Second experiment:
During cooling (not reported on detail), no effects were observed which were due to crystallization of the test substance. During heating, a glass transition was observed at approximately -75°C as well as an exothermic peak between -50°C and -25°C and two endothermic peaks. The first endothermic peak was observed between 0°C and 25°C. The extrapolated onset temperature of the peak was 9.12°C. Melting of the test substance caused this effect. A second ensothermic peak was observed between 175°C and 250°C. The extrapolated onset temperature of this peak was 229.04°C. This effect was caused by boiling of the test substance. After the experiment it was observed that the etst substance has evaporated from the sample container.
Third experiment:
During cooling (not reported on detail), no effects were observed which were due to crystallization of the test substance. During heating, a glass transition was observed at approximately -75°C as well as an exothermic peak between -50°C and -25°C and an endothermic peak between 0°C and 25°C. The exothermic effect was caused by crystallization of the test substance. The endothermic peak with an extrapolated onset temperature of 9.96°C was caused by melting of the test substance. After the experiment, a colourless celar liquid residue remained in the sample container.
