Cellulose Triacetate (CTA), identified by its CAS number 9012-09-3, is a synthetically modified polymer derived from cellulose. Its unique characteristics stem from a rigorous acetylation process, distinguishing it from partially acetylated cellulose derivatives like cellulose acetate. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer in China, specializes in the production of high-purity CTA, catering to diverse industrial demands.

The chemical foundation of CTA lies in cellulose, a natural polymer composed of repeating glucose units. In the production of Cellulose Triacetate, cellulose undergoes esterification with acetic anhydride, typically in the presence of an acid catalyst. This reaction replaces nearly all of the available hydroxyl groups (–OH) on the glucose units with acetyl groups (–OOCCH3). The degree of substitution is key; in CTA, at least 92% of the hydroxyl groups are acetylated, leading to the molecular formula C40H54O27 and a molecular weight of approximately 966.84 g/mol. This complete acetylation is what confers CTA its superior properties.

Physically, Cellulose Triacetate typically presents as a granular solid. Its appearance can range from white to a slightly yellow hue, indicating purity levels. A key characteristic is its melting point, generally falling between 120-160°C, which defines its processing window for applications like film extrusion or fiber spinning. The density is approximately 1.29 g/cm³. Solubility is generally limited in common solvents, often requiring specific organic solvents like chloroform for dissolution, which is critical for processes like solution spinning for fibers or casting for films.

The production process, involving the complete acetylation of cellulose, results in a polymer that exhibits significantly improved thermal resistance compared to cellulose acetate. This enhanced stability makes CTA highly valuable for applications requiring resistance to heat, such as in specialty films used in photography and LCD displays. Furthermore, CTA fibers are known for their excellent wrinkle resistance and ability to hold pleats, making them desirable for the textile industry. These specific Cellulose Triacetate properties are a direct outcome of its chemical structure.
