Eco-friendly polysorbate aqueous solvents for efficient dissolution of lignin†
Abstract
Herein green, low energy consuming and inexpensive solvents (polysorbate/H2O (Tween-80/H2O)) were developed, which could be readily prepared, instantaneously dissolve lignin without any heating, and hardly disrupt the structure of lignin. The facile lignin dissolution can be ascribed to the interaction between the Tween-80 chain and molecular chain of lignin.
