Answer :

The use of a large excess of alcohol can shift the equilibrium in the Fischer esterification to the right.

What is Fischer esterification?

Fischer or Fischer-Speier esterification is a special type of esterification involving the formation of an ester by refluxing a carboxylic acid and an alcohol using an acid catalyst.

Influence of alcohol on the Fischer esterification

The structure, molecular weight and type of alcohol have a marked influence on the rate of esterification and the degree of conversion at equilibrium.

Another factor that can shift the Fischer esterification equilibrium to the right is temperature.

The reaction rate increases with increasing temperature.

An increase in temperature can also amplify the equilibrium production, as occurs in most steriflcation reactions, but this comes to a controlled stop due to the boiling point of the alcohol of the acid, which is avoided if the reactor is works under pressure, allowing this to increase the temperature.
