Abstract

Surface tension values for 82 ethers have been compiled from databases, books, and papers in the literature. The data were carefully screened, and finally, 2122 values were selected. Each fluid dataset has been fitted with the Guggenheim–Katayama correlation with two, four, or six adjustable parameters, except diphenyl ether, for which the data taken from different sources clearly disagree. Thus, recommended correlations are proposed for 81 ethers. The proposed correlations provide mean absolute deviations equal to or below 0.5 mN/m and mean absolute percentage deviations below 2.6% for 79 ethers. Moreover, percentage deviations below 9.5% are obtained for all the selected data of 78 ethers. 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 esters.

醚表面张力的推荐相关性

82种醚的表面张力值已经从数据库、书籍和文献论文中编译出来。数据经过仔细筛选，最终选出2122个值。每个流体数据集都与两个、四个或六个可调参数的Guggenheim-Katayama相关性进行了拟合，但来自不同来源的数据明显不一致的二苯基醚除外。因此，提出了81种醚的推荐相关性。所提出的相关性为79种醚提供了等于或低于0.5 mN/m的平均绝对偏差和低于2.6%的平均绝对百分比偏差。78种醚所选数据的百分比偏差均小于9.5%。发现的最大偏差是由于从不同来源获得的数据之间的不一致，而不是相关性模型的数学形式不充分。这些相关性被添加到先前提出的不同流体的相关性集合中，包括普通物质、醇类、制冷剂、有机酸、正构烷烃和酯类。

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.
