Determination of Abraham model correlations for describing solute transfer into the methyl butyrate mono-solvent at 298 K

ABSTRACT

Experimental mole fraction solubilities have been determined for 27 crystalline nonelectrolyte organic compounds and for one organometallic compound (ferrocene) dissolved in methyl butyrate at 298.15 K. The crystalline compounds cover a wide range of polarity and hydrogen-bonding character. Abraham model correlations were derived by combining the solubility data measured in the current study with published values retrieved from the chemical and engineering literature. The mathematical correlations determined in the current study were found to back-calculate the observed solubility data to within standard deviations of 0.10 log units (or less).
