| Abstract: | The mechanism of the lactone ring opening of Crystal Voilet Lactone was investigated by means of 13C NMR.The structure of triphenylcarbenium ion and its stability were analyzed.The equilibrium constant between the lactone form and carboxyl form was obtained from 13C NMR data.The machanisms of opening and closing of the lactone ring in different conditions wcre discussed. |
