In this investigation, a kinetic study of the thermolysis of N‐(benzyl)‐N ́‐(tert‐butoxycarbonyl) sulfamide to yield benzylsulfamide in an efficient manner was performed. The thermolysis reaction was monitored in helium flow by thermogravimetry at different heating rates between 0.2 and 10 oC/min. The activation energy value was obtained from the Kissinger‐Akahira‐Sunose isoconversional method and theoretical calculations (from Transition State Theory). The reaction model of the process was studied by means of the master‐plot method. Results obtained from experiments of thermolysis performed under the melting point temperature of N‐(benzyl)‐N ́‐(tert‐butoxycarbonyl) sulfamide fit with an Avrami‐Erofeev model whereas data found for experiments at higher temperatures fit with first order model. Isothermal experiments were simulated at 115, 120 and 130 oC using the model‐free method, employing only the activation energy value.
