| Abstract: | It is studied that the composition of vinyl ester of rosin and the structures of the components by GLC and various spectrums. The results show that the vinyl ester of rosin consists mainly of vinyl abietate, vinyl palustrate and vinyl dehydroabietate in 11 : 3 : 2 (wt.), their vinyl group is a typical ABX system in the ~1H-NMR. |
