松香树脂酸乙烯酯的研究(Ⅱ)——松香树脂酸乙烯酯组成与结构的研究
STUDIES ON THE VINYL ESTER OF ROSIN (Ⅱ) ——Study on Composition and Structure of Vinyl Ester of Rosin
【摘要】 研究了国产特级松香树脂酸乙烯酯的组成与各组分的分子结构。结果表明国产特级松香树脂酸乙烯酯的主要成分是枞酸乙烯酯、长叶松酸乙烯酯和去氢枞酸乙烯酯，三者间重量比为１３∶３∶２，其连接在羧基上的乙烯基在核磁共振谱图中呈现为很好的ＡＢＸ系统。
【Abstract】 Composition of vinyl ester of rosin and structures of the components were studied by GLC and various spectra. Results show that vinyl ester of rosin consists mainly of vinyl abietate, vinyl palustrate and vinyl dehydroabietate in 11∶3∶2 (wt), their vinyl groups show a typical ABX system in the 1H NMR spectra.
