title: [Study on highly effective emulsified viscosity reducer FTIR and +H NMR].
abstract: 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.
