Decomp. temp.:

> 300 °C

Remarks on result:

other: Reaction and/or decomposition of the test substance were observed above 300°C (573K): boiling of the test substance was not observed below the temperature at which reaction and/or decomposition started.

Any other information on results incl. tables

Preliminary test: From approximately 350°C upwards the weight of the sample decreased significantly. At 407°C, the sample weight had decreased by 25%. After the experiment, a charred residue was observed on the lid of the sample container and a black molten residue (original colour: dark purple) remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test substance.

 

Main study: During the first experiment an endothermic peak was observed between 25°C and 75°C. The extrapolated onset temperature of the peak was 45.05°C. Melting of the test substance was most likely the reason for the effect. Starting at 300°C a relatively broad endothermic effect was found due to reaction and/or decomposition of the test substance (observed between 300°C and 375°C). After the experiment, a dark purple molten residue remained in the sample container.

Applicant's summary and conclusion

Conclusions:

Reaction and/or decomposition of the test substance were observed above 300°C (573K): boiling of the test substance was not observed below the temperature at which reaction and/or decomposition started. Therefore, Custom Red #3 has no boiling temperature.
