摘要: 树脂酸是松香的主要成分,歧化松香质量的好坏,主要取决于树脂酸的组分及其含量.本文测定了五种树脂酸——枞酸、新枞酸、左旋海松酸、长叶松酸和脱氢枞酸的1H、13C、DEPT谱.并通过二维HMQC以及HMBC相关谱和模型化合物分别对其谱图的归属进行了详细的探讨.

关键词: 树脂酸, 歧化松香, 二维相关谱

Abstract: Resin acid is the main component of rosin, the quality of the disproportionated rosin is dependent on the amount of resin acid. The 1H NMR, 13C NMR,DEPT(θ=3/4π) spectra of abietic acid, neoabietic acid, levopimaric acid, pulustic acid and dehydroabietic acid have been determined. We also have assigned all peaks in the spectra by HMQC and HMBC coherenec spectra.

Key words: Resin acid, Disproportionated rosin, Two dimension coherence spectra
