Hi I'm trying to precipitate bisphenol A (its a measurable amount, not ppm like in water bottles). It has a 120g/L solubility in water, so I'm using ethanol as the solvent. I'm trying to find some sort of hydroxide that's soluble in ethanol but the resulting X2C15H14O2 that's insoluble in ethanol. Any suggestions? I tried doing a spectrophotometry analysis, reacting it with Iron(III) Chloride, but other compounds in the sample discolored it. My Teacher recommended  using Pb(OH)2 because PB(OH)C6H5 is insoluble (he said because the reaction with phenol is similar to the reaction with bisphenol). But It might not be soluble in ethanol.
