摘要
为了回收烟蒂的醋酸纤维(CA),用氯代1-烯丙基-3-甲基咪唑([AMIM]Cl)离子液进行了溶解和回收烟蒂CA试验。结果表明:①适宜的溶解温度137℃,溶解时间70min,在此条件下,20g[AMIM]Cl可溶解0.76gCA;②纯CA与回收品的FT-IR谱图一致;③[AMIM]Cl离子液体可以循环使用5次。
In order to reclaim cellulose acetate tow（CA）from cigarette butts,an experiment on dissolving and reclaiming CA in 1-allyl-3-methyl imidazole chloride ionic liquid（[AMIM]Cl）was conducted.The result showed that：1）appropriate dissolving temperature and time were 137 ℃ and 70 minutes,under which 20 g [AMIM]Cl could dissolve 0.76 g CA;2）the infrared spectrograph of pure CA agreed with that of reclaimed product;3）[AMIM]Cl ionic liquid could be used repeatedly for 5 times.
