Cellulose is dissolved using DMAc/LiCl and a reagent system is added to promote the acylation of an appropriate acid anhydride or free carboxylic acid. One reagent system includes N,N-dicyclohexylcarbodiimide (DCC) and 4-pyrrolidinopyridine (PP). Another reagent system includes p-toluene sulfonyl chloride (TsCl) and pyridine (Py).application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/98/233/055/0.pdf8296934536/58536/63536/64536/115536/119536/124C08B3/10C08B3/025523398
