Synthesis of propyl propanoic had been done. Propyl propanoic was synthesized via esterification of propanoic acid and 1-propanol in the presence of sulfuric acid catalyst with mole ratios of 4:3 to produce propyl propanoic. Structural characterization of products was done by means of IR, 1H-NMR, GC and GC-MS spectrometers. Esterification of propanoic acid with 1-propanol produced propyl propanoate in 72% yield.
