The solubility of adipic acid in methanol, ethanol, propanol, isopropanol, n-butanol, tert-butanol, acetone, 1,4-dioxane, acetic acid, and water was measured within the 0–60°C temperature range. Fumaric acid is a key intermediate in the tricarboxylic acid cycle for organic acid biosynthesis in humans and other mammals. Solvents that have a carbonyl functional group showed a very large increase in acid solubility… The modified Apelblat equation was more accurate than the … The trans isomer possesses a dipole moment. The acids studied were palmitic, stearic, oleic, elaidic, petroselinic, petroselaidic, linoleic, stearolic, arachidic, eicosenoic, behenic, erucic, and brassidic. This principle is often referred to as "like dissolves like," which means that polar molecules will generally dissolve well in polar solvents and non-polar molecules will generally dissolve in non-polar solvents.
