Surface tension of four oxygenated fuels: experiment and correlation

In this work, a pendant drop apparatus was developed and tested by the surface tension measurement of toluene. Then, the surface tensions of 2-Methoxyethanol, 2-Methoxyethyl ether, 2-Ethylhexyl acetate and Diethyl succinate were measured in the temperature range from (303.15-393.15) K. The surface tension correlations were developed as a function of temperature with the experimental data, and the average absolute deviations were 0.041 mN m−1, 0.064 mN m−1, 0.041 mN m−1 and 0.052 mN m−1 for 2-Methoxyethanol, 2-Methoxyethyl ether, 2-Ethylhexyl acetate and Diethyl succinate, respectively.
