Characterization of Organic Emissions from a Wood Finishing Product - Wood Stain

The emission charaaaistics of four organic compounds (non-ane, decam, undecane, and 1, 2, 4-trimethylbenzene)from wood stain have been measured in an environmental chamber It was found that the emission patterns of the four organic compounds can be described by a two-phase model. Phase 1 represents the period when the wood stain is relatively wet. Phase 2 is when the wood stain becomes relatively dry. The changes of emission mechanisms between the two phases were reflcted by the significantly different emission rate canstants measured during the two periods and the relationship between the relative rate constant, the relative vapor pressure, and the relative diffusivity. A double-exponential model was established that can be used to predict the relative emission rates of the four organic compounds fiom the wood stain.
