Synthesis principle of CAS No 77 94 1 tributyl citrate
We produce CAS No. 77 94 1 tributyl citrate by heating citric acid and n-butanol in the presence of a small amount of acidic catalyst. The catalysts include concentrated sulfuric acid, dry hydrogen chloride, and strong acid ion exchange resin.
We call this reaction as esterification. Esterification is a reversible reaction. When equilibrium is reached, there are a certain number of reactants and products. For example, when the same 1 mole of citric acid and 3 moles of n-butanol react in the presence of a small amount of sulfuric acid, part of the citric acid and n-butanol are converted into CAS No 77 94 1 tributyl citrate when equilibrium is reached.
This process mainly involves the following steps:
Raw material selection
The synthesis of CAS No 77 94 1 tributyl citrate mainly uses citric acid and n-butanol as raw materials. Citric acid is an organic acid, while n-butanol is an alcohol. The two react under specific conditions to form esters.
Catalyst effect
In the synthesis process of CAS No 77 94 1 tributyl citrate, the catalyst plays a key role. People use concentrated sulfuric acid as a catalyst in the traditional production process. But this method has many disadvantages, such as many side reactions, low product purity, and severe equipment corrosion. Therefore, researchers have made efforts to develop new catalysts and improve the synthesis process and product quality. The new catalysts include such as p-toluenesulfonic acid, inorganic salts, heteropoly acids, and solid superacids.
The optimal process conditions for the synthesis of CAS No 77 94 1 tributyl citrate include acid-alcohol ratio. Also the conditions include catalyst dosage, reaction time, reaction temperature, etc.
In summary, the synthesis of tributyl citrate is a process of combining citric acid and n-butanol through an esterification reaction. Most importantly, the selection of catalysts and the conditions of use have an important influence on the quality and performance of the product.
