Abstract
Synthesis of propanol from propanoic acid had been done. Propanol was synthesized via two steps. They are; esterification of propanoic acid and methanol in the presence of the sulfuric acid catalyst with the mole ratio of 4:3 to produce methyl propanoate, and reduction of methyl propanoate with sodium using ethylene glycol as the solvent to yield propanol. Structural characterizations of methyl propanoate and propanol were done using IR, 1H-NMR, and GC spectrometers. The results show that esterification of propanoic acid with methanol produced methyl propanoate in 75% yield. Reduction of methyl propanoate using ethylene glycol as a solvent produced propanol in yield of 77%.
