Abstract
The goal of this study is to synthesize stanol from palm oil distillate. Sterols as a by product from cooking oil distillation were extracted from a saponification reaction with organic solvent. The isolated sterols were 22-dihydrobrassicasterol (13.7%), stigmasterol (6.27%) and sitosterol (80%). The yield of sterols from palm oil distillate was 82 percent. The sterols were converted to stanols via a hydrogenation reaction by dissolving sterols in isopropyl alcohol in a ratio of 1: 2.5 w/w with 2% palladium on carbon as a catalyst for a period of 1 h at 85-90 °C. These stanols were epiergostanol (13.7%) and stigmastanol (86.27%). The final yield of stanol from sterol was 99.97 percent. Chemical structure of these sterol and stanol compounds were confirmed by infrared spectrometry and gas chromatography with mass spectrometry.
