Abstract
Methods of separating chitin from a chitinous biomass that contains chitin and non-chitin material by a chemical pulping process that uses a protic ionic liquid or a composition comprising acid and base precursor molecules are described. Also described are methods for purifying chemically pulped chitin resulting in a pure chitin material with a high molecular weight and a higher degree of acetylation in comparison to traditional pulping and ionic liquid extraction based methods.
