ABSTRACT

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 to 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.
