[Bmim]Cl双水相体系对猪皮皮粉溶解性能的研究
The Dissolvability of Pigskin Hide Powder in the [Bmim] Cl Aqueous Two-phase System
摘要
Abstract
[Bmim]Cl was synthesized by n-butyl bromide and N-methylimidazole, with acetone as the solvent. [Bmim] Cl, salt and deionized water were mixed to form ionic liquids aqueous two-phase system which dissolved pigskin hide powder. The different kinds of salt and the different mass fraction pigskin hide powder were studied and characterized respectively, influencing the dissolvability of pigskin hide powder in ionic liquids aqueous two-phase system. It showed that salt in the aqueous two-phase system for K2HPO4 and for 62.5 mg/mL dissolved pigskin collagen when it was best. What' s more, when the dosage of pigskin hide powder was 11%, the solution had already saturated. FT1R spectra was used to observe the recycled ionic liquids and the regeneration of pigskin collagen. The recycled ionic liquid was well, and the , regeneration of pigskin collagen of the secondary structure of collagen didn' t changed.关键词
