Abstract

Experimental solubilities are reported for 3,4-dimethoxybenzoic acid dissolved in 16 alcohol, 5 alkyl alkanoate, 5 alkoxyalcohol and 6 ether
solvents. The measured solubility data were correlated with the Abraham solvation parameter model. Mathematical expressions based on
the Abraham model predicted the observed molar solubilities to within 0.083 log units.

Key words: 3,4-dimethoxybenzoic acid solubility, alcohol solvents, alkyl acetate solvents, alkoxyalcohol solvents, solute descriptors.
