Abstract
Methyl ethyl ketone peroxide (MEKPO), the topic material, has been extensively applied as
an initiator and cross–linker during polymerization, but it has also induced many severe
accidents on a global scale. The innovative objective of an isothermal kinetic evaluation was
to determine the basic characteristics of reactive chemicals to prevent serious runaway
accidents. Therefore, we endeavored to demonstrate the reaction model and kinetic
parameters, such as activation energy (Ea), and frequency factor (A), by the thermal activity
monitor III (TAM III) under three isothermal situations of 70, 80, and 90°C, in terms of 31
mass% MEKPO and with 99 mass% acetone. The results showed that MEKPO could liberate
a great quantity of heat during an exothermic reaction. In addition, acetone could alleviate the
degree of exothermic runaway while being added with MEKPO.
