I know calcium ammonium nitrate (CAN) is used for cold packs. By bending a small metal plate the salt gets dissolved in water (separated pack) and this process is endothermic.
I would like to heat this calcium ammonium nitrate solution to get back anhydrous CAN. Is there a way I can do it without safety issues?
- Source 1 advices to heat it up to 210 °C.
- Source 2 mentions the possibility to decompose at 60 °C into nitrogen oxides
Do you think I can heat the mixture up to 100 °C?
