RESULTS Melting point value in C: >400C (No melting observed). Decomposition (yes-temperature C/ no fambiguous): No Sublimation(yes/no/ambiguous): No Remarks: Measurements of the melting point / melting range were limited to 400C, the maximum specification for the instrument used. Fine droplets were not observed to adhere uniformly or otherwise to the walls of the melting point tubes. CONCLUSIONS The melting point /melting range was not observed and therefore could not be determined. Remarks: While no meltingofthe test substance was evident, discoloration of the test samples was observed. The white powder tumed toa light brown and eventually black as temperatures rose.
