| 摘 要： | 硫酸盐木素经常压和加压磺化改性后，其红外光谱特征有明显改变。常压改性的木素大分子职的磺酸基因主要定位在苯环上，而加压改性的则主要在与苯环相联接的侧链上，红外光谱说明了它们之间的不同。

| Abstract: | The infrared spectrum of sulfate ligins is distinctly changed after they are sulfonated and modified under an ordinary pressure or a compression.It is proved that.under an ordinary pressure,the sulfoacid radicals of modified lignin huge molecules are mainly joined to benzene ring while,under a compression,they are mainly joined to lateral chain linked with benzene ring.The infrared spctrum displays the differentiations between them. |

| Keywords: | lignin infraed spectrum sulfonation lateral chain sulfoacid radical |
