Organic chemistry synthesis esters

Date:21.06.2016, 18:46 Description: When a carboxylic acid is treated with an alcohol and an acid catalyst, an ester is formed (along with water). This reaction is called the Fischer esterification. Notes: The reaction is actually an equilibrium. In our experiment we are using an excess of carboxylic aicd (acetic acid which is also known as ethanoic acid). From the balanced chemical equation, you will also appreciate that the presence of water in the reaction mixture will drive the equilibrium to the left, favouring the formation of. K. Chakraborti, B. Singh, S. V. Chankeshwara, A. R. Patel, J. Org. Chem., 2009, 74,. Silica chloride is an efficient catalyst for esterification of carboxylic acids with alcohols as well as for transesterification of esters by both alcoholysis and acidolysis. The mechanism for proton transfer can alternatively be drawn as follows: Note that the acid is a catalyst here (regenerated at the end) and serves two purposes. First, it makes the carbonyl carbon a better electrophile (Setting up step 2) and also allows for the loss of H2O as.
