    Abstract
    Amination reaction of azelaic acid included with reaction of an amide formation, in used ammonia pressure with Nickel catalysts and occurred on temperature 180 oC for 5 hours. The product of amide compound mixed in a pyrex glass with CaO and Al2O3 and heated at temperature 300 oC for 10 minutes under vacumm condition. A solid product extracted with n – heksan, removed to the autoclave, then mixed with Nickel catalyst, reducted by H2 at 200 psi of pressure and temperature 120 oC for 15 hours. The product was an amine compound with a few nitrile compound. The test method of material have been taken with FT – IR and 1H – NMR spectroscopy, the data showed that transformed of azelaic acid to amide compound, amide compound to nitrile compound, then became a Nonana-1,9-diamine.

Hasil amida ini dicampur dalam gelas pyrex bersama CaO dan Al2O3 dipanaskan pada suhu 300 oC selama 10 menit dalam vakum. Hasil padatan diekstraksi dengan n – heksan, dipindahkan ke dalam autoclave, kemudian dicampur dengan katalis Nikel, direduksi dengan H2 pada tekanan 200 psi pada suhu 120 oC selama 15 jam. Hasil yang diperoleh berupa amina disertai sedikit senyawa nitril. Uji zat hasil dilakukan dengan spekstroskopi FT – IR dan 1H – NMR, data menunjukkan perubahan asam azelat menjadi amida, amida menjadi nitril, kemudian menjadi Nonana-1,9-diamina
