Case Study

Molten Iron(III) Chloride Hexahydrate Used for Hydrolysis to Prepare Cellulose Nanocrystals

Yang, Weisheng, et al. ACS Sustainable Chem. Eng. 2023, 11, 27, 10172-10182.

Acid hydrolysis pretreatment of lignocellulosic fibers with ferric chloride hexahydrate (FeCl3·6H2O) enables economical and environmentally friendly production of cellulose nanocrystals (CNCs).
Preparation Process
· During the treatment of molten FeCl3·6H2O, the degree of polymerization (DP) of cellulose fibers decreased sharply, and at the same time cellulose I transformed into cellulose II microcrystals.
· Molten FeCl3·6H2O rapidly hydrolyzes cellulose fibers within 5 minutes at 80°C, resulting in a rapid decrease in polymerization from 922 to 196 and a water-insoluble solid (WIS) retention rate of 80.1%.
· CNCs were successfully produced from the mechanical disintegration of the WIS with a low energy input. Hence, the yield of CNCs is consistent with that of the WIS.
· Moreover, FeCl3·6H2O was easily recycled from the hydrolysate after hydrolysis, with a high recovery of 94.0-94.5 wt %, using simple concentration and crystallization technologies.
