Applicant's summary and conclusion
- Conclusions:
- The GLP study was performed according to EU method A.2 without deviations and therefore reliability of Klimisch 1 has been assigned. Boiling point has been determined to be 299°C.
- Executive summary:
The boiling point at 299 °C of the test substance was determined in a GLP test according to EU method A.2 using the distillation method. The test item was filled in a distillation flask and heated up until beginning of boiling. Due to the melting point of 128 °C the temperature in the gas-room of the distillation flask was read off, when the vapour front reached the thermocouple in the gas-room and condensed there.
The atmospheric pressure at the time of measurement was 1028 hPa. The temperature of the thermocouple of the gas-room was 300 °C when the vapour began to condensate. The temperature of the liquid was 298 °C at this time. A temperature correction according to Sidney-Young gives a boiling point at normal pressure of 299 °C.
