In this study, hydroxyapatite (HAP) was prepared by using the co-precipitation method and used as a catalyst support material. 25 % KOH loaded HAP catalyst was prepared by wet-impregnation method and basicity of synthesized catalyst was found to be 1.6 mmol/g. Synthesized solid basic catalyst was tested for the soybean oil transesterification with methanol at different reaction temperatures (25-65°C) and different alcohol/oil molar ratios (6/1-15/1) when catalyst amount of 3 wt.% and reaction time of 5 h were kept constant. The chemical structure and purity of the fatty acid methyl esters obtained in this study was verified by the ATR-IR spectroscopy method. Methyl ester yield of 93.3% was obtained by using KOH loaded HAP solid basic catalyst which was found to be very successful catalyst

Bu çalışmada, hidroksiapatit (HAP) katalizör destek malzemesi olarak birlikte çöktürme yöntemine göre hazırlandı. %25 potasyum hidroksit (KOH) HAP destek malzemesine ıslak emdirme yöntemi ile yüklenerek yapının bazikliği 1,6 mmol/g olarak bulundu. Elde edilen katı bazik katalizör soya yağının metanol ile transesterleşme tepkimesinden biyodizel (yağ asidi metil esterleri) üretimi için farklı sıcaklık aralığında (25-65°C) ve farklı alkol/yağ oranında (6/1-15/1) kütlece %3 katalizör miktarında 5 saat süre ile test edildi. Elde edilen soya yağ asidi metil esterlerinin saflığı ve yapısı ATR-IR spektroskopisi doğrulandı. KOH yüklenen HAP bazik katı katalizörü soya yağının transesterleşme tepkimesinde %93,3 metil ester verimi vererek oldukça başarılı bulundu.
