Applicant's summary and conclusion

Conclusions:
Disodium-naphthalene-1,5-disulphonate monohydrate showed no exothermic decomposition up to 500 °C.
Executive summary:

With a screening DTA (based on DIN 51007) A sample of disodium-naphthalene-1,5-disulphonate monohydrate in a melted glass container was heated up in a DTA oven with a linear rate of 3 K/min up to 500 °C.

Disodium-naphthalene-1,5-disulphonate monohydrate showed no exothermic decomposition up to 500°C.
