摘要
纤维素是自然界含量最丰富的可再生资源,开发一种具有应用前景、环境友好、生物可降解的新型绿色溶剂成为近年来的一项主要任务。综述了传统纤维素的溶解方法,包括铜氨溶液体系和二硫化碳/氢氧化钠(CS2/NaOH)体系,介绍了新型纤维素溶剂NMMO、离子液体等,探讨了各种体系的溶解机理及其优缺点,并在此基础上提出了溶剂法生产纤维素纤维的进展和趋势。
Cellulose is the most abundant natural renewable resources, so the development of a prospective, environmentally friendly, biodegradable solvent has become one of the main tasks in recent years. The traditional methods for dissolving cellulose are introduced, including copper ammonia solution system and carbon disulfide/sodium hydroxide （CSz/NaOH） system. The new-type cellulose solvents, sueh as N-methylmorpholine-N-oxide （NMMO）, i- onic liquid are also summarized. The dissolving mechanism, the advantages and disadvantages of various systems are discussed. The future development tendency of producing cellulose fiber is prospected.
