Solubility of Benzoic Acid in Pure Solvents and Binary Mixtures : 75-09-2. As for why benzoic acid is soluble in low-polarity solvents like dichloromethane, a lot of it has to do with the formation of dimers, in which the hydrogen bonding ability of the COOH groups are pretty much used up. Mixing of Solvents . PERTINENT MOLECULES. 24. It has a role as an antimicrobial food preservative, an EC 3.1.1.3 (triacylglycerol lipase) inhibitor, an EC 1.13.11.33 (arachidonate 15-lipoxygenase) inhibitor, a plant metabolite, a human xenobiotic metabolite, an algal metabolite and a drug allergen.It is a conjugate acid of a benzoate.

After a while, a formation of two layers was observed. I teach organic 1 lab and this is literally one of the labs students have to do (separating solid mixture of carboxylic acid and a "neutral" organic compound). The primary reason benzoic acid dissolves only slightly or poorly in cold water is that, because of a polar carboxylic group, the bulk amount of the benzoic acid molecule is non-polar.
