What is the advantage of using absolute ethanol rather than using 95% ethanol in this experiment?Experiment: Theoretical Mass of Ethyl-p Aminohenzoic Acid Paper

Experiment: Theoretical Mass of Ethyl-p Aminohenzoic Acid: If the 95% ethanol was used the little amount of water present in the diluted ethanol can prevent ester formation. This is because easter the presence of water could drive the reaction to the left. i.e. instead of acids becoming esters from the Alkyl group, the esters can become acids because of the hydrogen from the water. Therefore, the use of absolute ethanol is preferred which will drive the reaction to right, rather than using any forms of diluted ethanol that could only negatively influence reaction for ester formation.Experiment: Theoretical Mass of Ethyl-p Aminohenzoic Acid Paper

Why it is important to add the sulfuric acid drop wise to the ethanolic solution of p-aminobenzoic acid?

Sulfuric acid has been proven to be the most efficient catalyst for esterification. Water is a product of the esterification reaction, where increase in water quantity would the reverse reaction and decrease the yield of the reaction. But when the reaction is performed in the presence of a concentrated sulfuric acid (hydrophyllic), it will perform as a dehydration agent that will absorb the water molecules by produced from the reaction. So in the presence of a sulfuric acid catalyst, the reaction will be driven towards the right side, which is preferable to yield more ester. Theoretical Mass of Ethyl-p Aminohenzoic Acid Paper

The reason for adding this concentric acid in drop wise is mainly to avoid the extreme reaction of the acid with the water. Because, if excessive water was produced from the ethanolic solution of p-aminobenzoic acid, the sudden addition of large quantity of concentrated sulfuric acid could lead to extreme reaction with this excessive water, and result to a large amount of heat(exothermic). This is not safe and harmful in particular due to the use of concentrated sulphuric acid. In contrast, if acid was added as drops, the reaction will be still happening in the solution though will be limited only to a smaller extent. Therefore such procedure is preferable to maintain better control. Theoretical Mass of Ethyl-p Aminohenzoic Acid Paper

Another advantage of using drop wise adding of the acid would permit us to control the acidity of the final resultant. Because, if the acid content is increased in the final solution the subsequent neutralization process happens in the presence of an alkaline would lead to an extreme reaction. Therefore adding drop wise acid is essential to control the acidity of the solution, so the stability of the reaction can be maintained throughout. Theoretical Mass of Ethyl-p Aminohenzoic Acid Paper
