Prout-tompkins model
Webb24 aug. 2009 · Therefore, a methodology has been developed that allows for calibration of a single-reaction global kinetics model using One Dimensional Time to Explosion (ODTX) … WebbTompkins (1944) and Avrami-Erofeev (1939-1961) models. Burnham et al. (1996) compared these two models numerically and found that a simple mathematical extension of the Prout-Tompkins model, which we have called the 3-parameter or narrow profile model, gives a convenient form to fit this type of reaction model.

Webb15 juli 1985 · The first stage (∼ 290°C) is exothermic overall and the second (∼ 620°C) is endothermic. Kinetic studies of the first stage of the decomposition in vacuum led to the introduction of the Prout—Tompkins equation (ln (α/ (1 − α)) = kt + c) and a mechanism involving branching nuclei to account for this autocatalytic behaviour.
