In the ESI+ mode the compound isolated from fraction III/9 showed a pseudo-molecular ion of m/z 261 ([M + 1]+) as well as sodium and potassium adducts with m/z 283 and m/z 299, respectively, thus suggesting a molecular mass of 260 Da.

在 ESI+模式下，从子馏分 III/9中提取出来的化合物分别出现了伪分子离子 m/z 261 ([M + 1]+)和纳钾加合物 m/z 283 and m/z 299，这样就暗示了260 Da 的分子质量。

Accordingly, as catalyst of light oil sweetening,the binuclear cobalt sulfonate phthalocyanine was selected in this paper. Due to the double active centers in a plane, bi-CoSPc not only increases the solubility in alkaline, but also avoids its dimerisation, which expects to increase the catalyst activity in sweetening process.

为此，本文选用双核酞菁钴磺酸盐作为轻质油品脱臭催化剂，该催化剂具有平面双核的分子结构，这不仅增加了其在碱液中的溶解度，同时也减弱了二氧加合物的形成趋势，有望在轻质油品催化氧化脱臭工艺中具有更高的催化活性和使用寿命。
