    Abstract: A process for recycling cellulose acetate ester waste comprising the steps of : providing a reactor, adding cellulose acetate ester waste and a hydrolyzing agent to the reactor to create an agent/waste mixture followed by hydrolyzing the cellulose acetate ester waste by agitating and heating the agent/waste mixture for a period of time to create a hydrolyzed mixture. The hydrolyzing agent is then distilled and/or separated from the hydrolyzed mixture followed by separating and removing solid material from the hydrolyzed mixture to create a water soluble product stream which includes monosaccharides, polysaccharides, partially hydrolyzed cellulose, acetic acid, or combinations thereof. The water soluble product stream is then collected.

    Abstract: Instilling an acidic catalyst to a reaction mixture can be beneficial during the acylation of cellulose. Methods described herein can comprise preparing a reaction mixture comprising an acylating agent and cellulose, instilling a catalyst comprising an acid to the reaction mixture at an overall catalyst loading level of about 1% or less by weight of the cellulose, and reacting the cellulose with the acylating agent in the presence of the catalyst, thereby forming an acylated cellulose.
