IR and NMR studies showed that phenolphthalein salts formed in the K2CO3-DMSO system existed as lactone-type structures while salts in the KOH-DMSO system existed predominantly as quinone-type structures. These structural features were useful in the explanation of the polymerisation mechanism of phenolphthalein in different systems.
