What is Tributyl Citrate (TBC)
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.

FAQ
What is Tributyl Citrate (TBC)?
What is Tributyl Citrate (TBC)?
In short, tributyl citrate (TBC) is a citric acid ester, a colorless oily liquid, soluble in most organic solvents. Indeed, tributyl citrate (TBC) manufacturers use citric acid and butanol in the presence of a catalyst to produce tributyl citrate (TBC). Further more, US FDA approved tributyl citrate (TBC) and its downstream product acetyltributyl citrate (ATBC) as safe and non-toxic plasticizers.
How are esters classified?
How are esters classified?
According to the chemical structure. People divided them into: (1) Phthalate esters; (2) Aliphatic dibasic acid esters; (3) Phosphate esters (4) Epoxy compounds; (5) Polymeric plasticizers; ( 6) Benzene polyester; (7) Chlorine-containing plasticizer; (8) Alkyl sulfonate ester; (9) Polyol ester; (10) Other plasticizers.
How are Tributyl Citrate (TBC) produced?
How factories to produce Tributyl Citrate (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 Tributyl Citrate (TBC)
Indeed, US FDA approved the main varieties of tributyl citrate (TBC) and acetyltributyl citrate (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., and people mainly use TBC as a plasticizer for cellulose resins and vinyl resins. Most inportantly, tributyl citrate is the raw material for producing acetyltributyl citrate (ATBC).
How to calculate the original consumption ratio of Tributyl Citrate (TBC)?
How to calculate the original consumption ratio of Tributyl Citrate (TBC) ?
Suppliers in China calculate as follows: Since citric acid is a tricarboxylic acid, if the alcohol involved in the reaction is a monol, then one molecule of citric acid reacts with three molecules of a monol to produce a molecule of tributyl citrate. So, if we multiply the coefficients corresponding to the chemical reaction in their respective molecular weights, therefore, the ratio between the three products is the ratio of raw material consumption.
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 catalyst can only accelerate the reaction speed, but has no effect on the composition of the balanced material. In order to increase the yield of esters, manufactuers and suppliers in China often added excessive carboxylic acids and alcohols, or they constantly removed the resulting water from the reaction mixture. If the boiling point of the ester produced is very low, as a result, factories can steam ester out. In short, the equilibrium has changed to improve the yield of ester. For example, the industrial production of ethyl acetate in factories use excessive acetic acid, factories or suppliers in China steamed the generated ethyl acetate and water azeotrope (water 8.6%, ethyl acetate 91.4%, constant boiling point 70.45℃) out. So that the balance has changed, and then factories continue to add acetic acid and ethanol, continue to steam ethyl acetate and water, continuous production.
What is saponification?
What is saponification?
People call the hydrolysis of esters in alkali solution as saponification reaction, which is because the advanced fatty acid salt obtained by alkaline hydrolysis of grease is the reason of soap.
