摘要
本文研究了定量测定1-羟乙基-2-烷基-2-咪唑啉的方法。该法以氯仿为溶剂,用红外光谱测定样品在1600cm^(-1)处的吸光度。当样品中烷基咪唑啉的含量为2~30gL^(-1)时,其吸光度与浓度呈线性关系。方法的标准差偏为0.80~1.20%。
Quantitative determination method for(l-hydro-xyethyl)-2-alkyl-2- imidazoline was developed.Chloroform as solvent, absorance of solution of sample containing alkylimidazoline was determined at 1600 cm-1 by IR. There is a linear relationship between absobance and concentration of solution in the range of 2-30gL-1. The standard derivation of this method is 0.80-
