Now when phthalophenone is hydrolyzed with alkalies it yields mono-carboxy tri-phenyl carbinol which on reduction yields mono-carbozy tri-phenyl methane and this by loss of carbon dioxide yields tri-phenyl methane. This means that phthalophenone is a lactone inner anhydride of mono-carboxy tri-phenyl carbinol and a true tri-phenyl methane derivative as shown in the reactions below. Now, also, phthalophenone by nitrating yields a di-nitro compound which by reduction yields a di-amino derivative and this by the diazo reaction has the two amino groups replaced by hydroxyls. The result is phenol phthalein, which is therefore also a lactone inner anhydride of mono-carboxy di-hydroxy tri-phenyl carbinol. All of these relationships may be represented by the following ...
