| Abstract: | Diphenyl carbonate(DPC) was synthesized by transesterification from ethylene carbonate and phenyl acetate using Ti(OBu)_4 as a catalyst.The reaction mixture was qualitatively analyzed by GC-MS.The analysis results showed that the mixture consists of DPC,2-phenoxyethyl acetate,2-acetyloxyethyl phenyl carbonate(1),ethylene diacetate and phenol.The structure of 1 was(identified) by ~1H NMR,(~(13)C NMR,) FT-IR and EI-MS. |
