    Abstract
    The compound of 1,9-nonanediamide can be produced by amidation of azelic acid with urea in 82% yield. That compound was reduced with hydrazine-NaOH to produce 1,9-nonanediamine in 74% yield. Amidation of lactic acid with 1,9nonanediamine without solvent and catalyst, producing 1,9-dilaetocyl nonanediamine in 56% yield. Each step of reaction was characterized by analysis spectroscopy FT-IR and 1H-NMR. The compound of 1,9-dilactocyl nonanadiamine has an HLB value of 3.71, which can be used as a surfactant in dispersion w/o.
     
    Senyawa 1,9-nonanadiamida dapat diperoleh dari reaksi amidasi antara asam azelat dengan urea dengan rendemen 82%, dan selanjutnya senyawa 1,9-nonanadiamida yang dihasilkan dapat direduksi dengan hidrazin-NaOH menjadi 1,9-nonanadiamina dengan rendemen 74%. Asam laktat dapat diamidasi secara langsung dengan 1,9nonanadiamina tanpa pelarut dan katalis menghasilkan 1,9-dilaktosil nonanadiamina dengan rendemen 56%. Hasil reaksi di atas didukung dengan data hasil analisis spektroskopi FT-IR dan 1H-NMR. Senyawa 1,9-dilaktosil nonanadiamina tersebut merupakan suatu surfaktan dalam dispersi w/o yang memiliki harga HLB sebesar 3,71.
