And palm kernel oil (247 mg KOH gm) (Pearson, 1976). On the other hand, this saponification value is within exactly the same selection of some edible oils reported by Eromosele and Paschal (2002). Additionally, saponification worth (174.95) in the oil in this investigation is almost within the selection of (17587) ASTM (2002) specification for oils. In line with Pearson (1976), oils with reduce saponification values contain high quantity of long chain fatty acids. Consequently, the worth obtained for brebra seed oil contained higher quantity of higher fatty acids (because it is presented on Table six, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, three:298 http:springerpluscontent31Page 6 ofTable 5 Brebra oil chemical and physical characteristicsOil physicochemical characteristics Colour Density at 20 Specific gravity at 20 Kinematic Viscosity at 40 Acid worth pH worth Saponification worth Refractive index at 40 Iodine value Peroxide value Ester valueAll values are mean worth of triplicates.Unit Kgm3 kgl mm2s mg KOHgValues Pale-yellow color limpid liquid 0.942 0.926 40.59 0.39 6.mg KOHg174.95 1.GLUT2 drug gI2100 gm mEqKg104.48 6.88 174.chain accounts 92.8 ). The value of viscosity of brebra oil was 40.49 mm2s (as talked about above) is located to become less than the viscosity of cashew nut oil (56 mm2s) (Akinhanmi et al. 2008). For production of biodiesel, as a result, transesterification reaction could be the very best strategy to decrease the viscosity with the oil. The oil under investigation has quite low acid value of 0.39 mg KOHg when compared with cashew nut oil (0. 82 mg KOHg) (Aremu et al. 2006), refined castor oil (0.869) and crude castor oil (1.148) (Akpan et al. 2007), plukenetia conophoora (11.5 mg KOHg) as reported by Akintayo and Bayer (2002), aenniseed (47.6 ) by Ohsodi (1992). The acid worth in this oil is beneath the maximum limit (2.0 mg KOHg) of DIN EN ISO 660 and almost inside the selection of ASTM specification (0.four – 4.0) of castor oil (ASTM 2002).Table 6 Fatty acid composition of fatty acid of brebra oil (FAs = fatty acids)No 1 two three four 5 Fatty acids Unsaturated FAs Oleic Linoleic Linolenic Arachidonic Eurcic Total Saturated FAs 6 7 eight 9 Palmitic Stearic Arachidic Behenic Total C16:0 C18:0 C20:0 C22:0 7.two 1.9 3.3 six.9 19.three C18:1 C18:two C18:3 C20:4 C22:1 0.6 48.2 27.7 0.8 3.4 80.7 Carbon number Quantity ( )The low saponification worth and acid value imply that the oil is much more suitable for biodiesel since the oil acid value for biodiesel, which is much less than 1 . The iodine value of brebra oil was 104.48 gI2100 gm (inside the variety, 100-120 gI2100 gm, of DIN) that is greater than the selection of 774 gI2100 gm olive oil, 80 gI2 100 gm CXCR1 Compound coconut oil, 128 gI2100 gm palm kernel, 4458 gI2100 gm palm oil, 855 palme oleine, 205 gI2 100 gm palme stearine, 500 gI2100 gm tallow, 600 gI2100 gm lard, (http:dec2.tec.agrar.tu-muenchen.de pflanzoelrkstandarde.html) 44.four gI2100 gm cashew nut oil (Aremu et al. 2006), 38.1 gI2100 gm citrullus vulgaris (Achinewhu 1990), Hausa melon seed oil (38.50 gI2100 gm) (Oladimeji et al. 2001) and 84.eight gI2100 gm refined castor oil (Akpan et al. 2007). 1 the other hand, the iodine value of this study was lower than the range of 11015, 12535, 12540, and 11524 gI2100 gm worth of rapeseed oil, sunflower oil, soybean oil and corn oil, respectively. The oil within this study is considered drying oil considering that drying oils have an iodine worth above one hundred gI2100 gm (Duel and Tr 1951). The peroxide value of brebra oil was 6.88 mEqKg. It was higher than the peroxide value of 3.1 mEqKg of cash.
