Identification of chemical composition of biodiesel from Tabernaemontana divaricata seed oil

Abstract

Tabernaemontana divaricata Linn oil was extracted and transesterification was carried out using methanol as the solvent in presence of a catalyst to produce biodiesel. Fatty acid methyl esters in biodiesel prepared from Tabernaemontana divaricata seed oil was analyzed by IR, NMR and GC-MS. The composition of the biodiesel is estimated as 27.0 wt.% methyl palmitate (C16:0), 10.54 wt.% methyl linoleate (C18:2), 56.23 wt.% methyl oleate (C18:1) and 6.20 wt.% methyl stearate (C18:0).
