Abstract
Surface tension values for 80 esters have been compiled from databases, books, and papers in the literature. The data have been carefully screened and selected, and the final dataset for each fluid has been fitted as a function of the temperature by using the Guggenheim–Katayama model, which requires two or four adjustable coefficients for each fluid. As a result, recommended correlations are proposed for each of the 80 esters, providing mean absolute deviations below 0.55 mN/m, mean absolute percentage deviations below 2.2%, and percentage deviations below 10% except for 3 data out of 1846 selected. These correlations are added to the collection of those previously proposed for different kinds of fluids, including common fluids, alcohols, refrigerants, organic acids, and n-alkanes.
期刊介绍：
The Journal of Physical and Chemical Reference Data (JPCRD) is published by AIP Publishing for the U.S. Department of Commerce National Institute of Standards and Technology (NIST). The journal provides critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. Critical reviews may also be included if they document a reference database, review the data situation in a field, review reference-quality measurement techniques, or review data evaluation methods.
