The origins of phenolphthalein lie in the German chemical industry during the heyday of artificial dye discovery in the late 19 th century. An organic molecule made of only carbon, hydrogen and oxygen, it was first synthesised in 1871 by Adolf von Baeyer, who combined phenol and phthalic anhydride in the presence of sulfuric acid or zinc chloride - the same method that is still used for. Phenolphthalein is a triphenylmethane salt whose three aromatic rings produce a red chromophore in basic and neutral solutions. The conjugation is disrupted in acidic solutions resulting in a clear solution. Thus phenolphthalein is an effective acid base indicator for titrations of mineral acids, organic acids and alkalis Preparation of Phenolphthalein: it is prepared by condensation of phthalic anhydride with two equivalents of phenol under acidic conditions. Uses of Phenolphthalein: it is used to produce 2-(4,4'-dihydroxy-benzhydryl)-benzoic acid. The reaction occurs with reagent zinc, sodium hydroxide and solvent H 2 O with other condition of heating for 96.
