cellulose diacetate

Cellulose diacetate is a synthetic compound derived from cellulose, a natural plant substance. It is created by replacing some of the hydroxyl groups in cellulose with acetyl groups. This process makes cellulose soluble in certain solvents and allows it to be softened or melted by heat, enabling its use in various applications.1

Cellulose diacetate is produced through a partial reversal of the acetylation reaction of primary cellulose acetate, often using water. This results in a compound that can be dissolved in common solvents like acetone, making it suitable for dry-spinning into fibers. It can also be molded into solid plastic parts or cast into film. Historically, cellulose diacetate was used in safety film for photography and in the automotive industry for parts like tool handles and goggles due to its strength and ease of molding. Today, it is notably used for cigarette filters.12
