Hi Dhia,

Could you be more specific?

Acid with alcohol in presence of catalytic acid will offered ester.

Be specific about the synthesis of short or long carbon-chain alkyl esters.

Dear Aquar. Could you specify that kind of feedback do you expect from us?

Please specify your query and read content from published papers on enzymatic ester synthesis.

Esters are products of reactions between acids and alcohol molecules' functions which can be catalysed by brönsted acid. According to the catalysts nature and its rate which conditioned the reaction-pH and the esters rate, it's really possible to obtain citric acid's poly-ester on product.
