Abstract
Surface tension values for 79 esters, including aromatics, polyfunctional, and glycerides, have been compiled from databases, books, and papers in the literature. The data have been carefully screened, and finally, 1517 values were selected. Each fluid dataset has been fitted with the Guggenheim–Katayama correlation with two or four adjustable parameters. Recommended correlations are proposed for each ester, providing mean absolute deviations below 0.50 mN/m for 77 of them, mean absolute percentage deviations below 1.7% for 76 of them, and percentage deviations below 10%, except for four data out of the 59 selected for tricaprylin. The highest deviations found are due to the disagreement between the data obtained from different sources and not to an inadequate mathematical form of the correlation model. These correlations are added to the collection of those previously proposed for different fluids, including common substances, alcohols, refrigerants, organic acids, n-alkanes, and 80 other esters.
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.
