| Research Abstract |
In order to develop a prediction method of the vapor concentrations of multicomponent organic solvents in the work environment, we measured vapor concentrations emitted from a vessel temporally. A model for predicting multicomponent organic vapor concentrations were developed based on theories of the vapor-liquid equilibria and mass transfer rate. The experimental vapor concentrations were in good agreement with the predicted ones for 2 to 4 component of organic solvents.
