Resumo(s)
The possibility of using Annona seed oil as an
added value product, namely as a source of biodiesel, is
explored. Milled Annona seeds were extracted with hexane
at room temperature (72 h) and at solvent boiling point
(6 h). Oil content was found to be 25 and 22.4% respec tively. The oil was characterized in terms of lipid compo sition (HPLC–APCI–MS and 13C NMR), resistance to
oxidation and acidity index. FAME composition was
determined by GC–MS and five major peaks were identi fied. Production of biodiesel from Annona’s seed oil was
achieved by base-catalyzed transesterification. Density,
viscosity, refraction coefficient, acid value, cold filter
plugging point, cloud point and oxidation stability were
measured. The iodine value and the ‘‘apparent cetane
number’’ were calculated. Density, viscosity, acid value,
iodine value, cold filter plugging point and cloud point
were within EN14214 specifications and the calculated
‘‘apparent cetane number’’ was also indicative of a suitable
product.
