Product Features
The free acid and water content in our product CAS No 77 89 4 acetyl triethyl citrate is low, ensuring that the hydrolysis reaction is not easy to occur.
Principle of hydrolysis reaction for CAS No 77 89 4
The hydrolysis reaction of esters is a reversible reaction. When there is a large amount of water, people can make the reaction complete. Equimolar esters and water form a balanced mixture in acidic or neutral solutions, while in alkaline solutions, since hydroxide ions are strong nucleophiles, once carboxylic acids are generated, they immediately form salts with the base, destroying the equilibrium and allowing the hydrolysis reaction to proceed to the end.
Properties of esters
When esters such as CAS No 77 89 4 react with alcohols under the catalysis of hydrochloric acid or sodium alcohol, we can generate another alcohol and ester. People called this reaction as transesterification. Transesterification is also reversible. For example, triethyl citrate reacts with n-butanol to produce tributyl citrate and ethanol.
Esters can react with ammonia to form amides. For example, people acetylate triethyl citrate to produce CAS No 77 89 4 acetyl triethyl citrate.
Esters can react with Grignard reagents to form tertiary alcohols.
Esters are easier to reduce than carboxylic acids. In synthesis, people often reduce carboxylic acids to alcohols through esters. The most commonly used reducing agent is sodium plus ethanol. The resulting alcohol is either the alcohol used in the original esterification reaction or the primary alcohol generated by the reduction of the acyl group.
Conditions for the hydrolysis of CAS No 77 89 4
The conditions for the hydrolysis of esters include acidic conditions and alkaline conditions.
Under acidic conditions, ester hydrolysis usually involves heating with dilute sulfuric acid, which is an incomplete hydrolysis and a reversible reaction. For example, we can convert acetyl triethyl citrate back to citric acid and ethanol.
