内容記述 | Acrylic acid is a monomer that has been responsible for a number of severe explosions worldwide as a result of thermal runaway. The present work was intended to lead to an improved understanding of the kinetics of the thermal polymerization and Michael addition reaction (MAR) of acrylic acid. Sealed cell differential scanning calorimetry was carried out, and the kinetics of the thermal polymerization of acrylic acid were assessed on the basis of the model-free Friedman method. In addition, microcalorimetry using a Thermal Activity Monitor IV apparatus was conducted to determine the kinetic parameters for the MAR. The rate constant for the MAR was found to be k (s^−1) = 3.45 × 10^5 × exp (− 9.48 × 10^3/T (K)), while the activation energy was 78.8 kJ mol^(−1). The progress of the MAR was fitted with an n-order reaction model, and the reaction order as well as the rate constant was determined to be linearly proportional to temperature. By employing a modified n-order reaction model in which the reaction order was a linear function of temperature, we obtained a reaction rate equation for the MAR that closely reproduced the experimental results over a wide temperature range. | |||||
