A sustainable homogeneous transcarbamoylation/transurethanization protocol for cellulose modification with methyl N-substituted carbamates was developed. The protocol utilizes the superbase ionic liquid [mTBNH][OAc], not only as a green reaction medium, but also as a promotor of the transformation. This approach allows to obtain different cellulose carbamates with controllable degrees of substitution. The solubility of the obtained materials from the newly developed method was compared with the solubility of materials obtained from the isocyanate approach, where some intrinsic trends were observed.

在超强碱-酸共轭离子液体中通过氨基甲酸甲酯的转氨甲酰化/转氨基甲酸酯化制备纤维素氨基甲酸酯


开发了一种可持续的均质转氨甲酰化/转氨基甲酸酯化方案，用于用 N-取代氨基甲酸酯进行纤维素改性。该方案利用超强碱离子液体[mTBNH][OAc]，不仅作为绿色反应介质，而且作为转化的促进剂。这种方法可以获得具有可控取代度的不同纤维素氨基甲酸酯。将通过新开发的方法获得的材料的溶解度与通过异氰酸酯方法获得的材料的溶解度进行比较，观察到一些内在趋势。
