    Abstract
    A medium chain triglyceride ( 1,2-dicapryl-3-oleoyl-glycerol) has been synthesized from glycerol via ketalization, esterification, deketalization, and reesterification reactions, respectively. Glycerol was ketalized with aceton to produce solketal. Solketal was esterified with oleic acid to produce 2,2-dimethyl-4-methyl-oleoyl-1,3-dioxolane. Then this compound was deketalized with 1 N hydrochloric acid to obtain 3-oleoyl-glycerol. This compound was reesterified with caprice acid to give 1, 2-dicapryl-3-oleoyl-glycerol. The compound which produced in each step of reaction was identified by FTIR, 1H-NMR, dan 13C-NMR spectrometers.
     
    Trigliserida rantai sedang 1,2-dikapril-3-ofeil-gliserol telah disintesis dari gliserol berturut-turut melalui reaksi ketalisasi, esterifikasi, deketalisasi dan reesterifikasi. Gliserol diketalisasi dengan aseton untuk menghasilkan solketal. Solketal yang terjadi diesterifikasi dengan asam oleat menghasilkan senyawa 2,2-dimetil 4-metil-oleil-1,3-dioksolan. Selanjutnya senyawa ini dideketalisasi dengan asam klorida 1 N menghasilkan 3-Oleil-gliserol. Kemudian senyawa ini direesterifikasi dengan asam kaprat menghasilkan 1,2-dikapril-3-oleil-gliserol. Senyawa yang terbentuk pada setiap tahap reaksi diidentifikasi dengan spektroskopi FT-IR, 1H-NMR, dan 13C-NMR.
