From the viewpoint of environmental protection and sustainability, developing green synthetic processing methods for cellulose derivatives, the most abundant biomass on Earth, is crucial. In this study, allyl cellulose was synthesized under homogeneous conditions. Cellulose was first dissolved in a tetrabutylphosphonium hydroxide aqueous solution, after which the resulting solution was derivatized with allyl bromide (AllylBr) to yield allyl cellulose. Allyl cellulose with a degree of substitution (DS) of 1.66 - 2.15 was synthesized at 25℃ within 1h. The DS values of the products could be well controlled simply by adjusting the AllylBr addition rate. Overall, the studyʼs findings provide insights into the development of a facile and highly efficient energy-saving synthetic method for allyl cellulose.
