NINGBO INNO PHARMCHEM CO.,LTD. offers valuable insights into Glycerol Triacetate, commonly known as Triacetin. This section delves into its synthesis, fundamental properties, and its widespread importance across numerous industrial applications.

The synthesis of Glycerol Triacetate is primarily achieved through the esterification of glycerol with acetic acid or acetic anhydride. Historically, this process involves reacting glycerol with acetic acid, often in the presence of an acid catalyst, driving the reaction towards the formation of the triester. Modern methods may employ catalysts and advanced techniques like microwave irradiation to optimize yield and purity, achieving up to 99% conversion. The efficiency and cost-effectiveness of these synthesis routes are crucial for meeting market demand. The availability and price of acetic acid and glycerol are key factors influencing the final cost of Triacetin.

Chemically, Glycerol Triacetate (C9H14O6) is a triglyceride, representing the triester of glycerol and acetic acid. It is characterized by its colorless, oily liquid form, a relatively high boiling point, and a low melting point. Its excellent solubility in organic solvents, coupled with slight solubility in water, makes it highly versatile for various applications. Key physical properties include a density of approximately 1.16 g/mL and a flash point around 140-148°C, indicating its stability and manageable handling characteristics.

The industrial significance of Triacetin is vast. It is widely employed as a plasticizer in polymers like PVC and cellulose acetate, imparting flexibility and durability. In the food industry, it serves as a solvent for flavors and a humectant, approved by regulatory bodies. Its role as a pharmaceutical excipient includes functions as a humectant, plasticizer, and solvent in drug formulations. Additionally, it finds use as a fuel additive to improve engine performance and as a component in cosmetics and other specialty chemicals.
