This research studied the potentials of the seed oil of Hibiscus mutabilis for biodiesel production. The oil was extracted
using a soxhlet extractor and n-hexane as a solvent before being transesterified into biodiesel. The results obtained showed a low
yield of 17.6 ± 0.1 % for the extracted oil. The oil showed a high acid value of 14.02±0.09 mgKOH/g, which indicated high free fatty acid content and the percentage yield of the biodiesel produced was 77.38 ± 0.5%. Fuel properties (color, cloud point, pour point,
sulfur content, kinematic viscosity, and specific gravity) determined showed compliance with American Standard Testing and Material (ASTM) and European standard specifications. The profile of methyl esters showed that unsaturated linoleic acid methylester was dominant. The results suggested that Hibiscus mutabilis seed oil possesses some properties
that were suitable for biodiesel production
