【摘要】 本文研究了国产歧化松香乙烯酯的组成与各组分的分子结构。结果表明:国产歧化松香乙烯酯的主要成分是二氢枞酸和脱氢枞酸的乙烯酯,二者重量比为3:4;其乙烯酯上乙烯基在核磁共振谱图中呈现为很好的ABX系统;因为二氢枞酸有三个异构体,所以仅用光谱方法无法确定二氢枞酸乙烯酯环内双键的位置。

【Abstract】 The composition of vinyl ester of disproportionated rosin and the structures of the components were studied by GLC and various spectrums. The results showed that the vinyl ester of disproportionated rosin consisted mainly of vinyl ester of dihydroabietic acid and dehydroabietic acid in 3 : 4 (wt), their vinyl group was a typical ABX system in the NMR. The double bond on the cycle of vinyl ester of dihydroabietic acid could not be found in firmly place by it’s NMR spectrum due to having three isomers.
