Amidasi Asam Pelargonat menjadi Pelargonamida Menggunakan Katalis Nikel

Abstract

Pelargonamide (nonanoamide) has been synthesized by reacting pelargonic acid and ammonia gas at a pressure of 100 psi and the temperature of 1800C for 8 hours using a nickel catalyst with a yield of 81 %. The FT-IR spectrum of pelargonamide shows absorbances at 3359 cm-1 and 3192 cm-1 attributed to stretching -NH2 from amide and absorbances at 1633 cm-1 attributed to bending NH from amide. And its 1H-NMR spectrum shows five chemical shifts at δ 6,11 ppm (s) and δ 5,68 ppm (s) attributed to proton –C(O)NH2; δ 2,18 ppm (t) attributed to proton -CH2-C(O)NH2; δ 1,59 ppm (m) attributed to proton -CH2-CH2-C(O)NH2; δ 1,29 ppm (m) attributed to proton -(CH2)5-CH2-CH2-C(O)NH2; and δ 0,86 ppm (t) attributed to proton CH3-(CH2)5-CH2-CH2-C(O)NH2. Both of FT-IR and 1H-NMR spectra indicates that pelargonamide has been formed.
