松香树脂酸乙烯酯的研究——马来海松酸乙烯酯的合成与结构的研究

Studies on the vinyl ester of rosin——study on the synthesis and structures of vinyl maleopimarate

研究了马来海松酸乙烯酯的合成反应条件与产物的分子结构。结果表明马来海松酸乙烯酯可以在有机锡和一些稀土金属盐的催化下合成出来。马来海松酸乙烯酯上的乙烯基在核磁共振谱图中呈现为很好的ＡＢＸ系统，其他光谱特征与马来海松酸相同。

The conditions of synthesis for vinyl maleopimarate and the structures of the products were studied.The results show that vinyl maleopimarate can be synthesized in the presence of organotin compound and some rare earth salts.The vinyl group in the vinyl ester is a typical ABX system in NMR,other spectral characteristics are the same as in maleopimaric acid.
