Abstract:
Micro- and nano-sized cellulose fibers can be prepared from various of techniques. Chemical pretreatments followed by low energy mechanical treatments were well-studied technique due to its simplicity and high-efficiency.
The main problems of chemical pretreatment were corrosion from acid or alkaline solution and chemical waste treatment. In this work, a mixture of zinc chloride (ZnCl2) - lactic acid (LA) was prepared as deep eutectic solvent
(ZnCl2-LA DES) for pretreatment of lignocellulose materials. The ZnCl2-LA DES has high solid loading capability,
low-corrosion, reusability and environmentally friendly profiles. Under optimum condition, ZnCl2-LA DES can be used for pretreatment of lignocellulose materials. The pretreated fibers can be isolated to micro- to nano-sized fibers by low energy mechanical treatment. Furthermore, we can isolate lignin from lignin-rich solution by precipitation methods. The used ZnCl2-LA DES was then purified and can be reused up to 5 times. The Zinc ions can be isolated from the used solvent by simple precipitation from solution for recycling and the left solution was 100% biodegradable. With ZnCl2-LA DES pretreatment technique, we can design a simple procedure to isolate valuable chemical goods from lignocellulose materials with low environment impact
