A melting point tube was filled in triplicate withtest substanceDechlorane Plus 25, Intertek Reference10467868. As the test substance was a fine powder, it was not ground further before analysis.
An initial test was performed in triplicate using a temperature gradient of30°C to 400°C at a rate of 10°C/min. The test substance, a fine white powder, was observed to change colour to a light brown colour at 350°C, which then slowly darkened in colour as the temperature increased further until the test substance was observed to be black, indicating full decomposition at 380°C. No melt was observed. Due to the observed decomposition, a repeat test, over a narrower and slower temperature range, normally used to provide accurate melting point data, was not performed.

A melting point tube was filled in triplicate withtest substanceDechlorane Plus 515, Intertek Reference 10467870. As the test substance was a fine powder, it was not ground further before analysis.
An initial test was performed in triplicate using a temperature gradient of30°C to 400°C at a rate of 10°C/min. The test substance, a fine white powder, was observed to change colour to a light brown colour at 340°C, with spots of darker colour appearing at approximately 360°Cuntil the test substance was observed to be black, indicating full decomposition at 376°C. No melt was observed. Due to the observed decomposition, a repeat test, over a narrower and slower temperature range, normally used to provide accurate melting point data, was not performed.
Description of key information
