Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>In addition to polypropylene, acrylonitrile, and carbonyl alcohol, propylene oxide is the fourth major derivative among propylene derivatives and one of the important basic organic chemicals. A thermal stability test of catalyst, methanol, and hydrogen peroxide (H₂O₂) was conducted via differential scanning calorimetry (DSC). Propylene epoxidation with H₂O₂ over catalyst, methanol, and propylene evenly mixed by specific pressure was carried out, and then the runaway reaction under adiabatic conditions was further simulated by the vent sizing package 2 (VSP2) to measure temperature and pressure data with respect to time of the runaway excursion. Finally, the apparent activation energy of H₂O₂ and propylene oxide reaction was obtained via temperature variation equation to evaluate the degree of potential hazard in industry.</p> </abstract>
