一种金属洗涤剂的NMR分析

Dissection of a Cleaning Agent for Metals by NMR

提出利用NMR及其它实验手段对一种金属洗涤剂进行配方剖析的方法。该金属洗涤剂是由多种表面活性剂复配的产品,文中主要利用1H NMR和13C NMR对金属洗涤剂中的各组分尤其是各表面活性剂组分进行定性分析,并利用1H NMR特征峰对各组分进行定量分析。本法相对简便、准确。此方法同样适用于由非表面活性剂组成的其它精细化工产品。

A method for the dissection of a practicl cleaning agent for metals by NMR and other experi- mental methods is presented. The cleaning agent is a product composed of diversified surfactants. The ^1H NMR and ^13C NMR spectra were used to identify each of the components of the cleaning agent, and the characteristic peaks of their ^1H NMR spectra were used for their quantitative analysis. The developed method could also be applied to the analysis of other fine chemical products composed of non-surfactants.
