Thermal Stability Evaluation of Nitroalkanes with Differential Scanning Calorimetry

The thermal stability of a set aliphatic nitroalkanes, comprising primary and secondary with short long linear chains or cyclic, was tested by differential scanning calorimetry (DSC) analysis, for comparative purposes. An exothermic decomposition phenomenon high entity occurred all compounds, no significant difference observed to depend on the structure compounds tested. A maximum recommended process temperature (TD24) avoid is estimated studied compounds. Although TD24 values are difficult access under normal conditions handling storage in R&D labs, energy higher than 500 J/g, thus, attention should be paid, especially transportation, storage, handling. Yoshida correlation more conservative modified developed Pfizer were applied DSC data predict shock sensitivity explosive propagation. With most used correlation, some nitroalkanes predicted potentially sensitive as neat substances. Pfizer-modified flags shock-sensitive. information provided herein indicates inherent reactivity these could provide suggestions about precautions laboratory. In light this information, it advisable run accelerating rate evaluation experimental testing complete hazard assessment before employment an industrial scale.
