[求助] [BMIM]Cl IL (12.5 g)是怎么配的？有没有人了解这种试剂？已有1人参与

[BMIM]Cl IL (12.5 g) was heated at 130 C and cellulose (0.5 g) slowly added and allowed to completely dissolve for 2 h. Under vigorous stirring at room temperature, the cellulose IL solution was added dropwise, at the rate of 1 mL min1, into water to obtain cellulose spheres. The cellulose spheres were washed several times with water to remove the IL, until testing with AgNO3 solution showed no Cl was present. The cellulose spheres were divided into two parts: One part was dried overnight at 30 C to form solid cellulose spheres (SCS); the other part was frozen at 10 C for 5e6 h. The frozen spheres were immersed three times in ethanol for about 2 h each time, and then dried overnight at 30 C to form porous cellulose spheres (PCS).
