Engineers in performing process design require thermodynamic properties of substances. Selected thermodynamic properties, which are boiling point, freezing point, density of liquid, refractive index, critical properties, acentric factor, heat capacity of gas, vapor pressure, water solubility, and Henry's law constant are often required in engineering practice.; This work involved a deep insight into chemical journals, books, databases, web pages and estimation methods to predict thermodynamic properties. Property correlations have been developed for the thermodynamic properties. The correlation constants and estimated data are presented in tabular format especially applicable for rapid engineering usage. The agreement between correlation and data is good.; Correlations for water solubility of olefins, diolefins, and acetylenes are presented in this work. Henry's law constant for these hydrocarbons in water have also been ascertained. Representative values for Henry's law constant (atm/mol fraction) are 22190.4 for 1-pentene (C5H10), 4269.3 for isoprene (C5H8), and 1379.02 for 1-pentyne (C5H8).; The results for water solubility and Henry's law constant can be used for environmental applications. |
