This study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability). - Executive summary:
A study was performed to determine the melting temperature of the test item according OECD Method 103 and U.S. EPA. Test Guidelines, OPPTS 830.7220. The boiling temperature was determined using the caplillary/metal block method. Subsamples of the test substance were heated (in boiling point tubes and capillaries) using a temperature-controlled metal heating block instead of a liquid bath. The temperature at which a steady stream of bubbles emerged from the open end of a capillary tube submerged in the melted/liquid test substance was recorded and accepted as the boiling point. If a range of temperatures was noted between the first emergence of bubbles from the capillary tube until a steady stream emerged, a boiling range was reported. During the definitive boiling point testing the test substance samples provided a corrected mean boiling point of 180.4 ± 0.1°C (453.6K) and a mean corrected boiling range from 174.7 ± 0.9°C (447.9K) to 180.4 ± 0.1°C (453.6K) - for the three tests. Upon melting, the test substance was clear and light yellow. Upon removal from the instrument (at test termination), the test substance was amber in color.
