Abstract: Milled-wood lignins from whole cotton stalk and cotton stalk core respectively were isolated and purified through ball-milling,etc.These lignins were analyzed by means of ultraviolet spectroscopy, infrared spectroscopy and 13CNMR. The results indicated that lignins of cotton stalk are of guaiacyl-syringyl-parahydroxy phenylpropane(GSH) type. There are less parahydroxy phenylpropane and more syringyl units in lignin of cotton stalk bark and more syringyl and guaiacyl units in lignin of cotton stalk core.
Key words: cotton stalk, milled wood lignin, spectroscopic analysis
