Solubility of anthracene in binary alkane + 1-propanol and alkane + 1-butanol solvent mixtures

Abstract

Experimental solubilities are reported for anthracene dissolved in 12 binary mixtures containing l-propanol or l-butanol with hexane, heptane, octane, cyclohexane, methylcyclohexane, and 2,2,4-trimethylpentane at 25 OC. Results of these measurements are used to test two mathematical representations based upon the combined nearly ideal binary solvent (NIBS)/Redlich-Kister equation and modified Wilson model. For the systems studied, the combined NIBWRedlich-Kister equation was found to provide the better mathematical representation, with deviations between experimental and back-calculated values being on the order of f1.5 % or less.

“…The various S i "curve-fit" parameters can be evaluated via least-squares analysis. Published papers (Zvaigzne et al, 1993;Zvaigzne and Acree, 1994; have reported the calculated S i parameters for anthracene dissolved in eight of the nine sub-binary solvent systems, as well as the measured mole fraction solubilities in 1-propanol (x A sat ) 0.000 591), 2-propanol (x A sat ) 0.000 411), 1-butanol (x A sat ) 0.000 801), 2-butanol (x A sat ) 0.000 585), 2,2,4-trimethylpentane (x A sat ) 0.001 074), and cyclohexane (x A sat ) 0.001 553). Solubility data for the ninth binary solvent system was reported several years prior to the development of the combined NIBS/Redlich-Kister equation.…”

“…The model constants of eqs 1 and 2 along with the experimental solubility of anthracene in monosolvents were employed to calculate the solubilities. All calculated C m Sat solubilities were compared with the corresponding experimental values, and the mean deviation (MD) was calculated as an accuracy criterion by: (3) in which N is the number of data points in each set. Tables 1 and 2 list the experimental solubilities of anthracene, along with the back-calculated solubilities using eqs 1 and 2 and the densities of the respective saturated solutions.…”

“…The calculated model constants and MD values were computed and listed in Table 3 in which the solubilities were calculated with a reasonable MD (5.1 %), and this finding is in agreement with previous results. [3][4][5] Literature Cited…”

“…2 Anthracene, a simple PAH as a model solute, is the subject of a number of solubility studies, and experimental solubility data of anthracene in binary and ternary solvent mixtures have been reported in alcohols, ethers, alkenes, esters, and aromatic compounds by Acree and co-workers. [3][4][5][6][7][8][9] The authors did not study the solubility of anthracene in solvent mixtures containing ketones, nor has the effect of interactions between ketone and alcohol and ester cosolvents been thoroughly investigated in regards to the solubility of a dissolved solute.…”
