【Abstract】 The 13CNMR spectra of resorcin-formaldehyde resins synthesized with different catalysts are analyzed. According to quantitative calculation, it is assured that the main connection pattern of -CH2- group in resorcin-formaldehyde resins is ortho-pata (4(6)-6(4))connection. Moreover, the effects of different catalysts on the vacuum ratio of different position carbons of resorcin benzene ring are compared and probed. At the same time, IR spectra,which can be tested rapidly and cheaply, are used to replace 13CNMR spectra to testify the effects of different catalysts on the structure of the resorcin-formaldehyde resins.更多还原
