Solubility of Anthracene in Ternary Methyl tert-Butyl Ether + Alcohol + Heptane Solvent Mixtures at 298.15 K

Abstract

Experimental solubilities are reported for anthracene dissolved in ternary methyl tert-butyl ether + 1-propanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 2-propanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 1-butanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 2-butanol + 2,2,4-trimethylpentane, and methyl tert-butyl ether + 2-methyl-1-propanol + 2,2,4-trimethylpentane solvent mixtures at 25°C and atmospheric pressure. Nineteen compositions were studied for each of the five solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of the combined NIMS/Redlich-Kister equation. Computations showed that the model predicted the observed solubility behavior to within an overall average absolute deviation of about 1.7%, which is comparable to the experimental uncertainty of (1.5%.

Solubility in Binary Solvent Mixtures: Anthracene Dissolved in Alcohol + 2-Methyl-1-butanol Mixtures at 298.2 K

“…The predictive expression for the ternary solvent mixture is a mole fraction average of the logarithmic solute solubilities in the three pure solvents [(x A sat ) B , (x A sat ) C , and (x A sat ) D ] plus a Redlich-Kister summation term for each solvent pair. The documented success [11][12][13][14][15][16] of eq 3 in predicting anthracene solubilities in more than 60 different ternary solvent systems illustrates the need for measured solute solubilities in binary solvent mixtures.…”

“…More recently, Deng et al . − and Pribyla et al. − have shown that the S i coefficients determined by regressing experimental anthracene data in binary alkane + alkane, alkane + alcohol, alcohol + alcohol, alcohol + ether, and alkane + ether solvent mixtures allows one to predict anthracene solubilities in ternary alkane + alkane + alcohol, alkane + alcohol + alcohol, and alkane + alcohol + ether solvent mixtures. The predictive expression for the ternary solvent mixture is a mole fraction average of the logarithmic solute solubilities in the three pure solvents [( ) B , ( ) C , and ( ) D ] plus a Redlich−Kister summation term for each solvent pair.…”
