Description
Summary:Knowledge of the partitioning behavior of methanol in aqueous solutions is essential for estimating VOC emissions from pulp and paper mills. In this work, we report new data for partition coefficients of methanol in aqueous solutions containing sodium carbonate and sodium sulfate. The data show a linear dependence of partition coefficients of methanol with salt concentration. This linear dependence extends also to black liquor solutions containing sodium salts from pulp and paper mills. Furthermore, the data can be extrapolated in temperature and salt concentration using an extension of the relationship proposed by Harvey in 1998.
