塑料脱模剂一组分的光谱分析

Spectral Analysis of a Compound in Mould Release Agent of Plastics

柱层析色谱分离性能优良的新型塑料脱模剂 ,纯化后得一主要未知组分。用元素分析、红外光谱、核磁共振氢谱研究其结构特征 ,对其盐酸酸化前后红外光谱吸收峰及核磁谱带进行了归属分析并确定结构。结果表明 ,该组分为一表面活性剂N ,N 二羟乙基十二烷基胺。这为新型脱模剂的产品开发提供了依据。

This paper reported the structure of a main unknown compound which was isolated and purified by column chromatography from a new mould release agent used in plastics. Elemental analysis, infrared spectra and H-1 nuclear magnetic resonance spectrum were used to study the structure characters. The structure was then confirmed by. assigning infrared absorbing peaks and nuclear magnetic spectral bands of this compound and its hydrochloric acid-treated compound. It showed to be a surfactant, N, N-dihydroxyethyl. dode-cylamine. The result provides useful information for developing new mould release agents.
