A rapid, inexpensive, and simple high‐resolution NMR spectroscopic method is outlined for determining the content of surfactants and other low‐molecular‐weight organic compounds in detergent formulations. With simple sample preparation, quantitative results can be obtained from an internal standard and/or the method can be used as a fingerprint analysis of the surfactant composition. The NMR sample is prepared by suspending the detergent sample in deuterated acetic acid and thus dissolving surfactants and other organic compounds. Any content of carbonate will be liberated as CO2, whereas other inorganic materials are removed by centrifugation. From one‐dimensional 1H and two‐dimensional HSQC NMR spectra, the surfactant components and low‐molecular‐weight organic compounds can be identified from reference spectra. Intensities of signature signals in the one‐dimensional 1H NMR spectrum are used for quantification by comparing with an internal standard. Furthermore, it is demonstrated how 31P NMR can be used to identify and quantify phosphonate‐type chelators.

通过核磁共振波谱快速简单地鉴定和定量洗涤剂配方中的成分
概述了一种快速，廉价且简单的高分辨率NMR光谱法，用于测定洗涤剂配方中表面活性剂和其他低分子量有机化合物的含量。通过简单的样品制备，可以从内标物获得定量结果和/或该方法可以用作表面活性剂组合物的指纹分析。通过将去污剂样品悬浮在氘代乙酸中，然后溶解表面活性剂和其他有机化合物，来制备NMR样品。碳酸盐的任何含量都将释放为CO 2，而其他无机材料则通过离心去除。从一维1H和二维HSQC NMR光谱，表面活性剂组分和低分子量有机化合物可从参考光谱中识别出来。一维1 H NMR光谱中的特征信号强度通过与内标比较用于定量。此外，还证明了31 P NMR如何用于鉴定和定量膦酸酯型螯合剂。
