dc.description.abstractFatty acid methyl esters were produced from tobacco seed oil having high free fatty acid (FFA) content (13.02%). The high FFA content of tobacco seed oil was reduced to less than 2% in a 1 h reaction by a two-step process. The first step was acid-catalysed esterification reaction conducted at 50 oC using 1% w/w H2SO4, 18:1 molar ratio methanol with respect to the high FFA tobacco seed oil to produce methyl ester by lowering the acid value. The second step was transesterification of the treated oil obtained using 6:1 methanol to oil ratio. The following catalysts:1%w/w KOH, 2%w/w cocoa pod ash and 2%w/w rice husk ash were employed to produce fatty acids methyl esters at 65oC. The yields for fatty acids methyl esters obtained were 96%, 94.6% and 82% in 2h for KOH, cocoa pod ash and rice husk ash catalysts respectively.en_US
