Additional information

There are no available data on the boiling point of hydroxylammonium nitrate. However read across data for hydroxylamine, hydroxylammonium sulphate, and hydroxylammonium chloride were available. Hydroxylamine has a boiling point of 58°C whereas hydroxylammonium sulphate has a boiling point of 102°C. Hydroxylammonium sulphate and hydroxylammonium chloride are both quoted to decompose at temperatures above 120°C. It is likely that hydroxylammonium nitrate will also decompose at temperatures above 120°C and have a similar boiling point to hydroxylamine.
