Effect Of High Pressure Homogenization (HPH) On The Rheological Properties Of Pineapple Leaf Cellulose/[BMIM]Cl Solution

Due to the intermolecular and intramolecular strong hydrogen bonds, cellulose possesses high crystallinity, hardly dissolves in ordinary solvents. In the meanwhile, the cellulose, hemicelluloses and lignin were woven into compact structure, that is one of the reasons that natural cellulose poorly soluble in water and other organic solvent [1] Swatloski et al in 2002 first explicitly pointed out that ionic liquid, 1 - butyl 3 - methyl imidazole chloride salt ([Bmim]Cl) had good solubility of cellulose. The ionic liquids, with their excellent physical and chemical property, cause more and more concerns of people increasingly [2].You can take advantage of the ionic liquid ([Bmim]Cl) good solubility of cellulose by microwave heating way to dissolve cellulose in ionic liquids [3] [4]. As a new type of high-efficient green solvent, ionic liquid has unique properties, which is different from the traditional solvent. The highly effective and safe homogeneous treatment of pineapple leaf cellulose under microwave irradiation was reported in this paper. The rheological properties of pineapple leaf cellulose / [BMIM]Cl had a great change after the high pressure homogenization (HPH). Effect of high pressure homogenization on the rheological properties of pineapple leaf cellulose / [BMIM]Cl solution was investigated by rotational rheometer MARS III Haake (Germany).
