PREDICTION OF SATURATED VAPOR PRESSURE WITH SIMPLE STRUCTURE PROPERTY- PROPERTY RELATIONSHIPS

摘要

Pure component vapor pressure data are essential for process and product design, in assessing the environmental impact of a chemical compound and in modeling some types of toxicity (Dearden, 2003). At present, vapor pressure data are available only for a small fraction of the compounds of interest to the chemical industry. Even if the data are available they may not cover the full temperature range of interest. In product design vapor pressure values may be required for substances that have not been synthesized yet. Thus, prediction of saturated vapor pressure data is often essential.
