Description of key information
Additional information
Justification for classification or non-classification
The DTA thermogram of chlorosulphuric acid shows only endothermic effects above 150 °C, indicating decomposition into gaseous products.
From these results it can be concluded that chlorosulphuric acid is not a self-reactive substance as defined by the UN Recommendations on the Transport of Dangerous Goods, section 2.4.2.3, and the European CLP Directive (No. 1272/2008), Annex I, chapter 2.8.
