新型锦纶工业丝油剂的组成及结构剖析

摘要

A comprehensive analysis on the imported nylon industrial yarn oil is conducted through silica gel column chro-matography,IR spectroscopy,1H-NMR spectroscopy and ESI-TOF-MS spectrometry. 1H-NMR and ESI-TOF-MS are used to explore the distribution of polyoxyethylene (EO) and determine the structure of fatty acid esters with long alkyl chain. The result shows that oil is consist of water (21%), tetradecane (12%), octadecenoate decyl ester(42%), octadecenoate ethoxylate ether(4)(10%) and oleic acid ethoxylate ether(12)(15%). This method is widely used to determine the ingredients and proportions and gives reference for the development of the polyamide fibre oil.%结合运用硅胶柱色谱法、红外光谱法、核磁共振光谱法和电喷雾飞行时间（ESI-TOF-MS）质谱法，对一种国外新型锦纶工业丝油剂样品进行剖析，探究用1H-NMR和ESI-TOF-MS计算油酸聚氧乙烯酯类（EO）的分布及长碳链脂肪酸酯类结构的方法，确定油剂主要由水（21%）、十四碳烷烃（12%）、十八烯酸癸酯（42%）、油酸聚氧乙烯酯（4）（10%）和油酸聚氧乙烯酯（12）（15%）组成。此剖析方法对确定未知纺织油剂的成分和比例具有广泛的通用性，为下一步新型工业丝油剂的复配及研发提供依据。
