内容記述 | To clarify the thermal hazards of acrylic acid runaway polymerization, the amount of energy release and the products in each event of the polymerization sequence were investigated. The thermal hazard was analyzed using accelerating rate calorimetry (ARC), Karl-Fisher titration, and thermogravimetry-differential thermal analysis-mass spectrometry (TG-DTA-MS). The present study revealed that acrylic acid generates water, which increases the impact of tank destruction when the tank filling level is more than 15%. In addition, the Michael addition reaction of acrylic acid induces the monomer to polymerize due to its exotherm and produce Michael adducts, which generate larger amounts of gases and water than does the monomer. Therefore, the accumulation of Michael adducts increases the frequency of crack initiation in the tank, as well as the potential for tank destruction, due to the presence of monomer and water in the tank at a lower filling level than in the case of monomer alone. The present study determined that the accumulation of Michael adducts is the worst case scenario for accidents caused by acrylic acid. | |||||
