摘　　要：为制备纤维素与木质素,以芒杆为原料,在75％～80％的1,4-丁二醇水溶液中添加少量助剂,并在190℃～ 210℃条件下反应150 min制备得到纤维素和高沸醇木质素．高沸醇溶剂法制得的纤维素可用于造纸及加工成其他 纤维素产品,高沸醇木质素较好地保持了木质素的化学活性,灰分含量低于木质素磺酸盐,通过进一步改性具有广 阔的应用前景．1,4-丁二醇可以回收循环使用．In order to establish a new method for making cellulose and lignin from reed, a high boiling solvent （HBS） pulping process with aqueous solvent of 1,4-butanediol is investigated. Reed is pulped with 75～80% aqueous solution of 1,4- butanediol containing a small amount of catalyst at 190～210℃ for 150 minute. HBS reed pulp is suitable for making paper. Water-insoluble HBS lignin is separated from the liquor reaction mixture by water precipitation. Recovery high boiling solvent （RHBS） is able to recycle as a pulping solvent indicating that the HBS method is a pulping process of reed with saving resources and non-pollution. HBS lignin has better chemical activity and lower ash content than lignin suifonate.
