乳化降粘剂的红外光谱和核磁共振谱的分析研究

Study on Highly Effective Emulsified Viscosity Reducer FTIR and ^+H NMR

采取一系列分离方法对一种高效乳化降粘剂进行分离与纯化。用红外光谱对各组分的官能团结构进行了鉴定,用核磁共振氢谱及电喷雾离子质谱对相应组分进行了分析。推断其组分有表面活性剂烷基酚聚氧乙烯醚和N-月桂酰肌氨酸钠,在降粘剂固体含量部分中分别占26.6%和19.3%。高分子组分为聚丙烯酸丁酯,含量为9.0%。通过气相色谱-质谱分析技术对小分子助剂进行了分析,有2-乙基己醇,十二醇,十四醇。通过定性定量分析,该样品有高达27.2%的氢氧化钠及很少量的氯化钠,其余为水。

Separation and purification of a highly effective emulsified viscosity reducer were performed. The functional group of the components of the sample was characterized by FTIR. The corresponding components were indentified with ^＋H NMR and ESI-MS. It was deduced that the surfactants in the sample are 26.6% alkylphenol polyoxyethylene and 19.3% sodium lauroyl sarcosine. The macromolecule component in the sample is polybutylacrylate accounting for 9.0%. There is 27.2% NaOH in the sample and a little NaCl by qualitative and quantative analysis, and the residual is water.
