Solubility of 8-hydroxybenzoic acid in select organic solvents at 298.15 K

Experimental solubilities are reported for 2-hydroxybenzoic acid dissolved in 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol, 2-met hyl-2-propanol, 1-pentanol, 1-octanol, dibutyl ether, 1,4-dioxane, tetrahyd rofuran, ethyl acetate, butyl acetate, 2-propanone, 2-butanone, and cyclohe xanone at 298.15 K. Results of these measurements reveal that the observed solubilities in the eight alcohol solvents fall within a fairly narrow mole fraction range of each other. 2-Hydroxybenzoic acid is more soluble in bot h 1,4-dioxane and tetrahydrofuran than in any of the other alcohol, eater, or ketone solvents studied.
