Additional information
A study was conducted according to OECD test guideline 103, Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item. First differential scanning calorimetry was used. The test item was weighed out into a closed glass crucible under an inert atmosphere (nitrogen) and at ambient temperature. The filling height of the test item was approximately 10 mm. The sample tube was then put into the apparatus. The apparatus has a metal block with electrical heating system for the heating of the tubes. The tubes were heated to the set point of the measurement. Subsequently the fused boiling capillary, containing an air bubble in the lower part of the sample tube, was dipped in the sample tube after the test item was melted. From the set point the tube was heated with a constant heating rate to the maximum temperature. The maximum temperature of the equipment is limited to 400 °C. Set point and maximum temperature were chosen according to the results of the DSC measurements.
