Esterification is the process by which esters are formed when an alcohol reacts with an acid in presence of conc. Sulphuric acid.
R’OH + RCOOH → RCOOR’ + H2O
CH3CH2OH + CH3COOH → CH3COOC2H5 + H2O
Saponification reaction is when ester reacts with NaOH, to form sodium salt of acid and alcohol.
RCOOR’ + NaOH → RCOONa + R’OH
CH3COOC2H5 + NaOH → CH3COONa + C2H5OH
Esters are used in making perfumes, artificial flavouring agents, ice-creams, cold drinks.
Saponification process is used in making soaps.
