And palm kernel oil (247 mg KOH gm) (Pearson, 1976). Nonetheless, this saponification worth is within exactly the same array of some edible oils reported by Eromosele and Paschal (2002). Moreover, saponification value (174.95) in the oil in this investigation is virtually within the array of (17587) ASTM (2002) specification for oils. According to Pearson (1976), oils with decrease saponification values include high quantity of extended chain fatty acids. Consequently, the value obtained for brebra seed oil contained higher quantity of MAO-A list greater fatty acids (as it is presented on Table 6, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, three:298 http:springerpluscontent31Page six ofTable 5 Brebra oil chemical and physical characteristicsOil physicochemical traits Colour Density at 20 Precise gravity at 20 Kinematic viscosity at 40 Acid value pH worth Saponification value Refractive index at 40 Iodine worth Peroxide value Ester valueAll values are imply value 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.gI2100 gm mEqKg104.48 six.88 174.chain accounts 92.8 ). The worth of viscosity of brebra oil was 40.49 mm2s (as talked about above) is identified to become significantly less than the viscosity of cashew nut oil (56 mm2s) (Akinhanmi et al. 2008). For production of biodiesel, hence, transesterification reaction will be the ideal system to lower the viscosity of your oil. The oil below investigation has extremely low acid worth 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.five mg KOHg) as reported by Akintayo and Bayer (2002), aenniseed (47.six ) by Ohsodi (1992). The acid worth within this oil is below the maximum limit (two.0 mg KOHg) of DIN EN ISO 660 and almost within the selection of ASTM specification (0.4 – four.0) of castor oil (ASTM 2002).Table 6 Fatty acid composition of fatty acid of brebra oil (FAs = fatty acids)No 1 2 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 7.2 1.9 three.3 six.9 19.3 C18:1 C18:two C18:three C20:four C22:1 0.6 48.two 27.7 0.eight 3.four 80.7 Carbon quantity Quantity ( )The low saponification worth and acid worth imply that the oil is much more suitable for biodiesel because the oil acid worth for biodiesel, which is significantly less than 1 . The iodine value of brebra oil was 104.48 gI2100 gm (inside the range, ACAT supplier 100-120 gI2100 gm, of DIN) that is higher than the selection of 774 gI2100 gm olive oil, 80 gI2 100 gm 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). One the other hand, the iodine worth of this study was lower than the range of 11015, 12535, 12540, and 11524 gI2100 gm value of rapeseed oil, sunflower oil, soybean oil and corn oil, respectively. The oil in this study is regarded drying oil considering that drying oils have an iodine value above 100 gI2100 gm (Duel and Tr 1951). The peroxide value of brebra oil was six.88 mEqKg. It was greater than the peroxide worth of 3.1 mEqKg of money.
