In a previous study, we have shown that seeds of Ongokea gore (Hua) Pierre, which contain about 55% of oil (also called isano oil), possess interesting sustainable chemical applications .
To the best of our knowledge, there is no report on production of biofuel using isano oil. In this study, O.
Preparation of Ethyl Esters of Isano Oil. Synthesis of ethyl ester of isano oil was carried out by transesterification with sodium ethoxide according to the method of Christie .
The hydrogenated isano oil fatty acid ethyl ester was prepared following similar procedure.
Transesterification process yielded about 80% of Isano oil's FAEE which was attested by a quadruplet at 4.13ppm [sup.1]H NMR, due to methylene hydrogens of the ethyl carbon (C1) neighbors oxygen of the ester (Figure 1(b)).
Vinylic hydrogen atoms located in the region between 4.5 and 6.5 ppm in isano oil's [sup.1]H NMR (Figure 1(a)) disappeared in the [sup.1]H NMR of the hydrogenated product.
gore oil (B100), a biofuel obtained by ethanolic transesterification, B100H, which is a biofuel produced by transesterification of hydrogenated isano oil, and B20, a mixture of 20% B100 and 80% diesel.
