The spontaneous polymerization, i.e, runaway, of acrylic acid during storage is a serious problem which may endanger life and facilities. In respond to a starting polymerization, effective emergency measures are necessary. For these investigations, a polytropic reactor setup, namely, an isoperibolic reactor is introduced to offer a rational access to restabilization studies. Furthermore, safety diagrams are created where the used amount of stabilizer is plotted against the polymerization progress in terms of the rising temperature. Such diagrams display the minimum required amount of the shortstopper (RESTAB™) for terminating a runaway polymerization. The suitability of the reaction setup is investigated using unstabilized acrylic acid.
