Concentrated sulphuric acid. It is H2SO4 in a concentration of probably 6M or above.

The chemical equation is:CH3COOH + C2H5OH ↔ CH3COOCH2CH3 + H2OConcentrated sulfuric acid act as a catalyst.

a ml of 36n or 18m sulphuric acid should weigh approx 1.84g. This is because conc sulphuric acid's density is 1.84g/ml
When mixing conc. sulfuric acid and water, add acid to water and not vice-versa as that releases lot of energy resulting in injuries.

sulfuric acid or sulphuric acid
Because the esterification process is reversible, and we need the reaction to be one-way, the addition of sulphuric acid as a dehydrating agent stops the water from reacting with the ester to form back into an acid and alcohol. The sulphuric acid also acts as a catalyst for the reaction by protonating the carbonyl group oxygen, thus making the carbonyl group more electrophilic
