Remarks:

As the test material decomposed, no value for the boiling temperature could be determined however, using an adaptation of the Stein and Brown method (MPBP for Windows version 1441, 2000 US. Environmental Protection Agency), the boiling temperature was calculated.

Results

As the test material decomposed, no value for the boiling temperature could be determined experimentally. However using an adaptation of the Stein and Brown method (MPBP for windows version 1.41, 2000 U.S. Environmental Protection Agency), the boiling temperature was calculated to be 543 °C.

Conclusions:

The test material has been determined to melt with evidence of gradual decomposition at 481 ± 0.5 K at 101.05 to 101.62 kPa. As the test material decomposed, no value for boiling temperature could be determined. A calculated value of boiling temperature gave a result of 543°C.

Executive summary:

Melting/Freezing Temperature and Boiling Temperature. Melted with evidence of gradual decomposition at 481 ± 0.5 K, at 101.05 to 101.62 kPa by differential scanning calorimetry, using ASTM E537-86, Methods Al and A2 of Commission Directive 92/69/EEC. No value for boiling temperature could be determined. A calculated value of boiling temperature gave a result of 543^oc.
