What is Tributyl Citrate Used For?
Tributyl citrate (TBC) is a citric acid ester, a colorless oily liquid, soluble in most organic solvents. Tributyl citrate (TBC) manufacturers use citric acid and butanol in the presence of a catalyst to produce tributyl citrate (TBC). People use tributyl citrate (TBC) and its downstream product Acetyl Tributyl Citrate(ATBC) as safe and non-toxic plasticizers. As a plasticizer, since it has strong solubility, oil resistance, light resistance, and has good mold resistance. So, it has good compatibility with most cellulose, polyvinyl chloride, polyvinyl acetate, etc., and we mainly use TBC as a plasticizer for cellulose resins and vinyl resins. How to produce High Purity Tributyl Citrate Plasticizer? Firstly, we need to distillation separation, secondly, neutral washing, so reduce the acid value and water to reduce the hydrolysis reaction.
Tributyl Citrate is commonly used as a non-toxic plasticizer in a variety of applications, including:
- Non-toxic PVC granulation: Used extensively in the production of non-toxic PVC products, TBC plasticizer enhances flexibility and durability while complying with health and environmental standards.
- Food packaging: Its non-toxic nature makes it ideal for packaging materials that come into contact with food.
- Medical products: Tributyl Citrate is employed in the manufacturing of medical supplies, where safety and resistance to chemicals are essential.
- Children’s toys: The non-toxic characteristics of TBC make it a preferred choice for toy production, eliminating the risks associated with phthalate-based plasticizers.
Applications of Tributyl Citrate in Polymers
Tributyl Citrate (TBC) is widely used as a plasticizer in polymer systems, particularly in the production of flexible PVC and vinyl resins. The benefits of Tributyl Citrate in PVC products include enhanced low-temperature resistance, good water and mildew resistance, and increased plasticizing efficiency. This makes TBC plasticizer a highly effective and eco-friendly option for various polymers, ensuring optimal performance in both industrial and consumer products.
Benefits of Tributyl Citrate in PVC Products
Compared to traditional plasticizers such as phthalates, Tributyl Citrate offers several advantages:
- Non-toxic and safe: Ideal for products in contact with sensitive environments, such as food packaging, medical supplies, and children’s toys.
- Low volatility and high efficiency: Provides long-lasting flexibility and durability to PVC products.
- Enhanced resistance: Tributyl Citrate improves water resistance, mildew resistance, and low-temperature performance in plastics, making it suitable for a range of demanding applications.
- Environmental sustainability: Unlike phthalates, TBC is biodegradable and has a lower environmental impact.
Compare Tributyl Citrate with Other Plasticizers
When comparing Tributyl Citrate to traditional plasticizers such as phthalates (e.g., DOP, DBP), TBC stands out due to its non-toxic nature and superior environmental profile. While phthalates are being phased out due to health concerns, TBC is increasingly used in food-grade and medical applications. Additionally, TBC plasticizer offers improved resistance to temperature and solvents, which makes it an excellent alternative in critical applications like children’s toys and medical devices.
Tributyl Citrate vs Acetyl Tributyl Citrate
Both Tributyl Citrate (TBC) and Acetyl Tributyl Citrate (ATBC) are citrate-based plasticizers used in non-toxic and food-grade applications. TBC is primarily used in PVC, vinyl resins, and other polymers. In contrast, ATBC has better compatibility with cellulose acetate. It is also preferred for its added flexibility in colder conditions. The choice between TBC and ATBC depends on the product’s specific requirements, such as exposure to extreme temperatures or the need for increased flexibility.

How are Tributyl Citrate (TBC) produced?
How factories to produce TBC ?
Citric acid reacts with butyl alcohol through esterification reaction, as well as distillation purification under the action of catalyst to generate citrate esters.
Do ester compounds need to be neutralized and washed with water to remove the catalyst after esterification?
Is it necessary to neutralize and wash with water to remove the catalyst?
If manufacturers use a catalyst that has good catalytic activity and can remove it from the system, then it doesn’t need neutralization and water washing, or a catalyst that forms a homogeneous phase with the ester at the reaction temperature and precipitates in a solid state after lowering the temperature.
What is esterification?
What is esterification?
Indeed, the carboxylic acid reacts with alcohol in the presence of a small number of catalysts (concentrated sulfuric acid, dry hydrogen chloride, strong acid type ion exchange resin) to form esters. Therefore, manufacturers call this reaction esterification. In short, esterification is a reversible reaction, and when equilibrium generated, a certain number of reactants and products are present.
What are the functional groups of citrate esters ?
What are the functional groups of citrate esters ?
The functional group of citrate esters is also -COO-. Dehydration of carboxyl group (-COOH) and hydroxyl group (-OH) form it in deed.
What are the applications of Tributyl Citrate (TBC)
What are the applications of TBC
Indeed, US FDA approved the main varieties of TBC and acetyl ATBC as safe and non-toxic plasticizers. Furthermore, citrate ester as a plasticizer, has strong solubility, oil resistance, light resistance, and has good mold resistance. In addition, it has good compatibility with most cellulose, polyvinyl chloride, polyvinyl acetate, etc.. As well as people mainly use TBC as a plasticizer for cellulose resins and vinyl resins. Most inportantly, TBC is the raw material for producing ATBC.
How to calculate the original consumption ratio of Tributyl Citrate (TBC)?
How to calculate the original consumption ratio of TBC ?
Suppliers in China calculate the reaction as follows: Citric acid is a tricarboxylic acid. One molecule of citric acid reacts with three molecules of monol to produce a molecule of TBC. By multiplying the coefficients for the reaction with their molecular weights, they determine the ratio of raw material consumption. Therefore, the ratio between the three products reflects the raw material consumption ratio.
What is the most commonly used cost-effective plasticizer ester?
Commonly used and cost-effective plasticizer
Indeed, manufacturers think that the most cost-effective plasticizers are dibutyl phthalate and dioctyl phthalate.
What esters can be used as mosquito repellents
What esters we can use as mosquito repellents
The ester offered from suppliers in China is Dimethyl phthalate
How are esters chemically named?
How do we chemically name esters?
In short, the word “ester” can be preceded by the corresponding carboxylic acid and alcohol names. The word “alcohol” can generally be omitted, that is, “some” acid “some” ester. But the ester of polyols, generally put the “acid behind, called” an alcohol an acid ester.”
How to increase the yield of ester?
How to increase the yield of ester?
In factories, heating and adding a catalyst only speed up the reaction. However, this doesn’t change the composition of the balanced material. To increase ester yields, manufacturers and suppliers in China often add extra carboxylic acids and alcohols. They also remove the water formed during the reaction. If the ester produced has a low boiling point, factories can steam the ester out of the mixture. This shifts the equilibrium, improving the ester yield. For example, in the industrial production of ethyl acetate, factories use excess acetic acid. They steam out the ethyl acetate and water azeotrope (water 8.6%, ethyl acetate 91.4%, constant boiling point 70.45℃). This shifts the balance. Factories then add more acetic acid and ethanol and continue steaming ethyl acetate and water for continuous production.
What is saponification?
What is saponification?
People call the hydrolysis of esters in alkali solution as saponification reaction. The reason is because the advanced fatty acid salt obtained by alkaline hydrolysis of grease is the reason of soap.
