The flash point is an important indicator of the flammability of a chemical. For safety purposes, many data compilations report the lowest value and not the most likely. This practice, combined with improper documentation and poor data storage method

Intelligent design of chemical-process equipment requires accurate thermophysical property values for pure components and mixtures including solutions. Databases used by practicing engineers should include the best numbers available and estimated unc

Most thermophysical-property databases (TPD) provide low-level quality control checks. This manuscript focuses on additional, higher-level data evaluations made possible by the breadth of data stored in the database. For example, thermodynamic equati

An automated property prediction package has been developed that permits rapid evaluation of group-contribution, corresponding states, empirical, and theoretical property estimation methods. The property prediction package, which is part of the DIPPR

A model, based on Helmholtz energy, that can be used to describe thermodynamics of NaCI solutions in the water near-critical region has been developed and tested as a function of temperature (350-400 °C), pressure (18-41 MPa), and solute concentrati

Vapor-phase association greatly affects the pure-component properties of carboxylic acids. This study uses density functional theory (DFT) calculations to quantify the size and distribution of oligomers present in n-aliphatic carboxylic acid vapors a

A group-contribution method has been developed to estimate the heat of sublimation (ΔHsub) at the triple point for organic solids. The correlation was developed using ΔHsub values from a training set of 218 compounds, and it was tested by comparing

Two group-contribution methods have been developed to estimate heat capacities of organic solids at ambient pressure. The power-law (PL) method utilizes an empirical temperature dependence, while the partition function (PF) method is based on the Ein

Tabulation of evaluated physical property constants and of their estimated uncertainties makes the DIPPR database a valuable tool for developing correlations for physical properties of pure fluids. In this study, we have used the DIPPR database to de

Group-contribution methods produce estimates of thermophysical properties from correlations that include summative contributions for the functional groups that make up a molecule. Accurately dividing or parsing a molecule into its constituent functio
