Surface Reaction Rate of Ozone and Alpha-terpineol on Polyvinylchloride and Glass
Abstract
Alpha-terpineol reacts rapidly with ozone in the gas phase but also adsorbs strongly to indoor surfaces. in this study, we quantify the effective reaction rate of terpineol with ozone on two representative indoor surfaces: glass and polyvinylchloride (PVC). We found that when these surfaces are equilibrated with α-terpineol over a range from 27ppb to 66ppb, they consume ozone about 100 times faster than they do when there is no α-terpineol. the reaction probability of ozone and adsorbed α-terpineol is at least 10 times higher than the gas phase reaction probability and the second order reaction rate constant is approximately 10-14 cm4 molecule-1 s-1 regardless of substrate or relative humidity. Extrapolating to the surface-area-to-volume ratio typical of indoor environments, ozone consumption rate by surface reactions with α-terpineol are about equal to that due to gas-phase reactions with α-terpineol.
