Guaiacol carbonate C??? ??, ??, ??

??

Guaiacol Carbonate is used in method for preparing Polycarbonate Polyol and compound comprising the Polycarbonate Polyol.

Purification Methods

Crystallise the carbonate from EtOH. It is estimated by bromination to the monobromo guaiacol carbonate m 178o (from EtOH) [Chernoff J Am Chem Soc 51 3073 1929]. [Beilstein 6 H 776, 6 I 386, 6 II 784, 6 III 4233.]
