Abstract:
The compound of resol resin dimer was isolated and prepared from resol resin crosslinker by gel permeation chromatography. The obtained fraction was analyzed by high performance liquid chromatography with purity over 95%, and identified by mass spectrometry,
1H-nuclear magnetic resonance (NMR),
13C-NMR and DEPT. With the compound as standard substance, the content of dimer in samples used in Shengli oilfield was 117.4 g/L under the following chromatographic conditions: C
18 column, gradient elution of methanol/water and detection wavelength 270 nm. The results indicate that the method is an accurate and reliable technique for determing resol resin dimer in the samples.
