Exothermic reactions of DCPD and protection against them



Dicyclopentadiene (DCPD), which is usually considered inert, undergoes exothermic reactions at high temperatures. These reactions initially lower the pressure but ultimately can generate very high pressures. Adiabatic and nonadiabatic laboratory data are presented and characterized into a kinetic model. Strategies are described for safeguarding against potentially high temperatures in DCPD containing vessels and for relieving overpressures should runaway reactions occur.
