摘要:利用HPLC-UV研究了异海松酸(iPA)UV光固化反应产物,从中检测到了一种具有较强紫外吸收的非聚合物成分。通过硅胶柱色谱和制备型HPLC分离得到了该物质,经气相色谱分析检验,其纯度为82.6%。通过UV-vis、FT-IR、MS、1H NMR及13C NMR等光谱分析研究,该物质的化学结构被鉴定为7-羰基-8,15-异海松酸(7-O-8,15-iPA),这是异海松酸的一种氧化衍生物,与文献报道结构一致。还探讨了异海松酸发生氧化反应生成7-羰基-8,15-异海松酸的反应机理。
A non-polymerized compound with strong UV absorption was detected during investigation on UV-cured product of isopimaric acid (iPA) by HPLC-UV. The compound was isolated through silica gel column chromatography and preparative HPLC in purity of 82.6 % analyzed with GC. It was identified as 7-oxo-8,15-isopimaric acid (7-O-8,15-iPA), a kind of oxi- dized derivative of iPA, by means of spectroscopic data of UV-vis, FT-IR, MS, 1H NMR and 13C NMR in accord with the data reported in references. The formation mechanism of 7-oxo-8,15-isopimaric acid from iPA was also predicted.
