- Abstract
To evaluate the thermal hazards of the synthesis process of (N5)6 (H3 O) 3 (NH>)4 Cl, the heat emission behaviors of the synthesis processes including diazotization, cycloaddition and oxidative cleavage of (Ns)6 (H3O)3 (NH))4 Cl were investigated by using reaction calorimeter RC1e. The reaction thermodynamic data including exothermic heat for each step, maximum heat generation rate, heat capacity and reaction heat per unit mass were determined. The results show that the total exothermic heat of diazotization, cycloaddition and oxidative cleavage reactions are 5.624, 19.638 and -0.815kJ. The maximum heat generation rates are 25.05, 12.34 and 2.76 W. The reaction heats per unit mass are 72.85, 74. 37 and - 10. 36J/g. The adiabatic temperature rises are 27.99, 23. 15 and - 8. 08 K. Diazotization and cycloaddition reaction are exothermic controlled by dosage, and the oxidative cleavage reaction is relatively mild. Based on the above results, hazard grades of the three steps in synthesizing of (N5 (H3O)3 (NH>)4CI are all low risk.
