    Abstract
    Oktadekilamina (Stearilamina) telah disintesis dengan mereaksikan oktadekil alkohol dengan gas ammonia pada tekanan 100 Psi dan suhu 180oC selama 8 jam menggunakan katalis Pd/C serta variasi penambahan aerosil dengan hasil maksimum 23,44%. Spektrum FT-IR oktadekil amina menunjukkan adanya pita serapan pada 3331,07 cm-1 dan 3163,26 cm-1 yang diberikan oleh regangan (stretching) –NH2 dari amina dan pita serapan 1643,35 cm-1 diberikan oleh tekukan (bending) NH dari amina dan spektrum 1H-NMR oktadekil amina menunjukkan adanya 4 kelompok pergeseran kimia yaitu pada δ ppm (t) menunjukkan proton dari CH2-NH2; δppm (m) menunjukkan proton dari CH2-NH2; δppm (s) menunjukkan proton daqri CH2-CH2-NH2; δ 0,85 ppm (t) menunjukkan protong dari CH3-CH2-CH2-NH2. Data dari kedua spektrum tersebut menunjukkan bahwa senyawa Oktadekil amina telah terbentuk.
     
    Octadecylamine (Stearylamine) has been synthesized from Octadecyl Alcohol with ammonia at a pressure of 100 Psi and the temperature of 180oC for 8 hours using Pd/C catalyst and aerosil amount variation with maximum yield 23,44%. Octadecyl amine FT-IR spectrum shows absorbances at 3331,07 cm-1 dan 3163,26 cm-1 attributed for -NH2 stretching from amine and 1643,35 cm-1 attributed for NH bending from amine and octadecyl amine 1H-NMR spectrum shows 4 groups of chemical shift at δppm (t) attributed to the proton from CH2-NH2; δppm (m) attributed to the proton from CH2-NH2; δppm (s) attributed to the proton from CH2-CH2-NH2; δ 0,85 ppm (t) attributed to the proton from CH3-CH2-CH2-NH2. Both of the FT-IR spectrum and 1H-NMR spectrum indicated that Octadecyl amine has been successfully synthesized.
