Description of key information
The product has a exothermic decomposition energy (at 271.2°C) of 84.7 J/g.
Additional information
A Differential Scanning Calorimetry was performed to know the behaviour of the test substance during a heating procedure under nitrogen and at the atmospheric pressure.
A exothermic peak was observed at 271.2°C, the decomposition energy of this exothermic event was 84.7 J/g.
The Regulation (EC) No.1272/2008 of the European Parliament and of the Council on classification, labeling and packaging of substances and mixtures specifies that when the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500°C, a substance or mixture shall not be classified as explosive.
Based on the results obtained with the Differential Scanning Calorimetry analysis. We can also concluded that the test item is not self reactive substance.
Indeed, the exothermic decomposition energy is lower than 300 J/g, so according to "Recommendations on the transport of dangerous goods Manual of tests and Criteria Fifth revised revision edition 2009" the test item should not be classified as auto reactive material.
An analogue substance "Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda" show a similar behaviour in function of the temperature. Indeed, a decomposition around 300°C as for the test substance. The enthalpy difference observed for the decomposition of the test substance is a little higher that for the analogue substance. But these parameters are lower than 85 J/g for the both substances.
