Purified cellulose is subjected to an acetylation reaction in acetic anhydride excess, which is used as an
acetylating agent; acetic acid is used as a solvent, and either sulfuric acid or perchloric acid is used as a catalyst [10,11].
We hypothesized that the acetate buffer used for enzymatic hydrolysis may act as an
acetylating agent to chemically convert morphine to 6AM.
(12) Cellulose acetate was produced through homogeneous acetylation of cellulose from SCB cellulose, which uses acetic anhydride as
acetylating agent, acetic acid as solvent, and sulfuric acid as catalyst (13).
