Abstract

Palm olein (PO_o) is widely used as edible oil in tropical countries. The lubrication properties and chemical compositions of PO_o being considered to be used as renewable raw material for biolubricant synthesis. PO_o is suitable to be used directly as biolubricant for medium temperature industrial applications. Palm olein has good viscosity index, oxidative stability, flash and fire point as a lubricant source. PO_o contains unsaturated triacylglycerols (TAG): Palmitin-Olein-Olein, POO (33.3 %), Palmitin-Olein-Palmitin, POP (29.6 %), which are very important to produce good lubricant properties. This unsaturated bond is preferable in chemical modification to produce biolubricant. The chemical compositions of PO_o were tested by using high performance liquid chromatography (HPLC) and gas chromatography (GC) techniques.

Abstrak

Minyak sawit olein (PO_o) digunakan secara meluas sebagai minyak masak  bagi negara-negara beriklim tropika. Sifat-sifat pelinciran dan komposisi kimia PO_o dinilai untuk digunakan sebagai bahan mentah dalam sintesis biolubrikan. PO_o sesuai digunakan secara terus sebagai biolubrikan untuk aplikasi industri bersuhu sederhana. Minyak sawit olein adalah baik sebagai sumber lubrikan berdasarkan indeks kelikatan, kestabilan oksidatif, takat kilat dan api. PO_o mengandungi triasilgliserida tak tepu (TAG): POO (33.3 %), POP (29.6 %) iaitu sangat pnting untuk menghasilkan  sifat-sifat lubrikan yang baik. Ikatan tak tepu diperlukan dalam modifikasi kimia untuk menghasilkan biolubrikan. Komposisi kimia PO_o diuji menggunakan teknik kromatografi cecair berprestasi tinggi (HPLC) dan kromatografi gas (GC).
