| 摘 要： | 通过多种核磁共振（NMR）技术（包括1H NMR、定量13C NMR、DEPT135、1H-1H COSY、1H-1H NOESY、1H-13C HSQC和1H-13C HMBC）技术，对季戊四醇硬脂酸酯润滑剂的组成进行了表征.结果表明：该润滑剂主要成分是单季戊四醇四硬脂酸酯，同时还含有少量的单季戊四醇三硬脂酸酯、单季戊四醇双硬脂酸酯、双季戊四醇硬脂酸酯和三季戊四醇硬脂酸酯，以及微量的多季戊四醇硬脂酸酯.

| Abstract: | A pentaerythritol stearate sample with unknown composition was analyzed by nuclear magnetic resonance (NMR) spectroscopy (i.e., 1H NMR, quantitative 13C NMR, DEPT135, 1H-1H COSY, 1H-1H NOESY, 1H-13C HSQC and 1H-13C HMBC). The results indicated that the sample contained mainly monopentaerythritol tetrastearate, but also had small amounts of monopentaerythritol tristearate, monopentaerythritol distearate, dipentaerythritol stearate and tripentaerythritol stearate, as well as a trace amount of multipentaerythritol stearate. |
