Preparation Method of Glycerol Triacetate (GTA)
Triacetin is typically synthesized through the esterification of glycerol with acetic acid. This process involves reacting glycerol with acetic acid in the presence of an acid catalyst. Here’s a simplified outline of the preparation method:
Reactants Preparation: Glycerol is mixed with acetic acid. The ratio of acetic acid to glycerol is often higher than 1:1 to drive the reaction towards the formation of triacetin.
Catalyst Addition: An acid catalyst, such as sulfuric acid, is added to the mixture. The catalyst speeds up the esterification reaction between glycerol and acetic acid.
Heating and Reaction: The mixture is heated, typically under reflux, to facilitate the reaction. The heating is maintained for several hours to ensure complete conversion of glycerol to triacetin. The reaction involves the sequential acetylation of the three hydroxyl groups of glycerol.
Removal of Excess Acetic Acid: After the reaction is complete, any excess acetic acid is removed. This can be done through evaporation or distillation.
Purification: The crude triacetin is purified to remove any unreacted glycerol, acetic acid, and other impurities. Distillation is commonly used for purification.
Quality Control: The final product is tested to ensure it meets required specifications, particularly purity and concentration.
This method results in the formation of triacetin along with diacetin and monoacetin as by-products. The proportions of these can vary based on reaction conditions and the ratio of reactants. The process can be adjusted to favor the production of triacetin specifically.

Development Prospect of Glycerol Triacetate (GTA)
In recent years, with the increasing demand for the quality of life and the continuous progress of medical technology, triacetin, as a chemical raw material with important functions, has been widely used in food, medicine, cosmetics and other fields. According to the market research report, the global triacetin market size grew from $490 million in 2014 to $650 million in 2018, and is expected to maintain a steady growth trend in the next few years.
At present, phthalate plasticizers dominated by toxic dioctyl phthalate (DOP) and dibutyl phthalate (DBP) occupy a dominant position in industrial applications, accounting for about 80% of the total plasticizer production. Now the production and consumption of plasticizers is very large, and the use is very wide, and the annual consumption is more than 2 million tons. These substances return to the natural environment causing varying degrees of pollution and harm. DOP has a potential carcinogenic risk, developed countries and regions in the world have taken corresponding measures to limit the scope of use of DOP, phase out DOP and other plasticizers and find suitable alternative products. In acute oral, long-term contact and injection experiments, triacetin showed no toxicity to human body, and the plasticizing effect was good, and it could replace DOP and other phthalic plasticizers.
Due to the accelerated elimination of toxic plasticizers and the development and promotion of new non-toxic plasticizers has become an inevitable trend. As a green, degradable and non-toxic plasticizer, triacetin can be widely used in PVC materials, PLA polyester materials, cellulose acetate, and PVAc materials, with good plasticizing effect, and can replace DOP and other phthalic plasticizers, and can achieve similar plasticizing effects of phthalic plasticizers. Therefore, the application prospect of triacetin as a plasticizer is wide and should be promoted vigorously.
