Considering biodiesel obtained from other types of WCO [1], the
boiling points at 10 vol%, 50 vol% in this study was 20–30 C lower
but was slightly higher at the boiling point at 90 vol%. This was because of the difference in the chemical properties of the raw materials. The WCO samples used in this study consisted mainly of
saturated short alkyl chain fatty acids (C12 and C14) compared
to other raw used frying oil samples being composed mainly of
oleic (53%) and linoleic (33%).
