And palm kernel oil (247 mg KOH gm) (Pearson, 1976). Having said that, this saponification value is within exactly the same array of some edible oils reported by Eromosele and Paschal (2002). Additionally, saponification worth (174.95) with the oil in this investigation is nearly within the array of (17587) ASTM (2002) specification for oils. In accordance with Pearson (1976), oils with reduced saponification values include higher quantity of lengthy chain fatty acids. For that reason, the worth obtained for brebra seed oil contained high quantity of greater fatty acids (since it is presented on Table six, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, three:298 http:springerpluscontent31Page 6 ofTable five Brebra oil chemical and physical characteristicsOil physicochemical traits Colour Density at 20 Specific gravity at 20 Kinematic Viscosity at 40 Acid value pH worth Saponification value Refractive index at 40 Iodine worth Peroxide worth Ester valueAll values are imply worth of triplicates.Unit Kgm3 kgl mm2s mg KOHgValues Pale-yellow colour limpid liquid 0.942 0.926 40.59 0.39 six.mg KOHg174.95 1.gI2100 gm mEqKg104.48 six.88 174.chain accounts 92.8 ). The value of viscosity of brebra oil was 40.49 mm2s (as described above) is found to be significantly less than the viscosity of cashew nut oil (56 mm2s) (Akinhanmi et al. 2008). For production of biodiesel, consequently, transesterification reaction is definitely the very best strategy to cut down the viscosity on the oil. The oil below investigation has really low acid worth of 0.39 mg KOHg when compared with cashew nut oil (0. 82 mg KOHg) (Aremu et al. 2006), refined CK1 review 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 (47.6 ) by Ohsodi (1992). The acid worth in this oil is below the maximum limit (2.0 mg KOHg) of DIN EN ISO 660 and almost inside the array of ASTM specification (0.4 – 4.0) of castor oil (ASTM 2002).Table 6 Fatty acid composition of fatty acid of brebra oil (FAs = fatty acids)No 1 two 3 4 5 Fatty acids Unsaturated FAs Oleic Linoleic Linolenic Arachidonic Eurcic Total Saturated FAs six 7 8 9 Palmitic Stearic Arachidic Behenic Total C16:0 C18:0 C20:0 C22:0 7.2 1.9 three.3 six.9 19.three C18:1 C18:two C18:three C20:four C22:1 0.six 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 extra acceptable for biodiesel since the oil acid worth for biodiesel, that is less than 1 . The iodine value of brebra oil was 104.48 gI2100 gm (inside the range, 100-120 gI2100 gm, of DIN) which is higher than the range of 774 gI2100 gm olive oil, 80 gI2 100 gm coconut oil, 128 gI2100 gm palm kernel, 4458 gI2100 gm palm oil, 855 palme ALDH3 Biological Activity oleine, 205 gI2 one hundred 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 worth of this study was reduce than the selection 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 thought of drying oil considering that drying oils have an iodine worth above 100 gI2100 gm (Duel and Tr 1951). The peroxide worth of brebra oil was six.88 mEqKg. It was higher than the peroxide value of 3.1 mEqKg of money.
