摘　　要：为了回收及充分利用废纸原料,用溴代1-乙基,3-甲基咪唑([Emim]Br)离子液体对废纸进行溶解实验。结果表明:适宜的溶解温度130℃,溶解时间10min,废纸与离子液体质量比为1:6,在此条件下,溶解百分率可以达到12.5%。废纸溶解再生产物的红外谱图与微晶纤维素基本吻合,说明废纸在离子液体中的溶解产物主要是纤维素,且纤维素在离子液体中的溶解属于直接溶解。In order to recover and make flail use of the waste paper which in production and life, dissolution experiments in the bromide 1-ethyl, 3- methyl limidazolium （[Emim] Br） ionic liquid carried out on paper. The results showed that, appropriate dissolution temperature was 130℃, dissolving time was 10min, paper and ionic liquid mass ratio was 1：6, in these conditions, the dissolution rate could reach 12.5%. The IR spectrum of recycled dissolved paper products were coincident with the microcrystaline cellulose, note paper the mainly dissolved production was cellulose in ionic liquid, and cellulose dissolved are directly dissolved in ionic liquids.
