| 摘 要： | 运用~(13)C-NMR法直接测得沥青芳香度f_a,同时应用红外光谱法(IR)测得1600cm~(-1),460cm~(-1),1380cm~(-1)吸收峰的吸光度,然后对两者关联,建立了f_a的光谱计算方程。该方程适用于一般精确度的沥青和渣油的f_a值的计算,误差不大于5.5%,与B-L法结果也较为一致。

| Abstract: | The relation between aromaticity Obtained by the method of ~(13)C-NMR and absorbance at 1600 cm~(-1), 1460 cm~(-1), 1380 cm~(-1) obtained by the method of IR spectrometry is studied. The equation of spectral calculation for f_a is established which can be used for calculating f_a of asphalts and residual oil with higher accuracy, the errors being less than 5.5% and the values obtained in agreement with that calculated by B-L method. |
