And palm kernel oil (247 mg KOH gm) (Pearson, 1976). However, this saponification value is inside the identical range of some edible oils reported by Eromosele and Paschal (2002). Additionally, saponification worth (174.95) of your oil in this investigation is just about inside the range of (17587) ASTM (2002) specification for oils. Based on Pearson (1976), oils with decrease saponification values include high volume of long chain fatty acids. Hence, the value obtained for brebra seed oil contained higher quantity of greater fatty acids (because it is presented on Table 6, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, three:298 http:springerpluscontent31Page 6 ofTable 5 Brebra oil chemical and physical characteristicsOil physicochemical qualities Colour Density at 20 Specific gravity at 20 Kinematic Viscosity at 40 Acid value pH value Saponification value Refractive index at 40 Iodine worth Peroxide worth Ester valueAll values are mean value of triplicates.Unit Kgm3 kgl mm2s mg KOHgValues Pale-yellow colour limpid liquid 0.942 0.926 40.59 0.39 6.mg KOHg174.95 1.HIV drug gI2100 gm mEqKg104.48 six.88 174.chain accounts 92.8 ). The worth of viscosity of brebra oil was 40.49 mm2s (as ALK7 web mentioned above) is discovered to be 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 very best strategy to decrease the viscosity on the oil. The oil below investigation has quite 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 (11.5 mg KOHg) as reported by Akintayo and Bayer (2002), aenniseed (47.6 ) by Ohsodi (1992). The acid worth within this oil is under the maximum limit (2.0 mg KOHg) of DIN EN ISO 660 and practically within the array of ASTM specification (0.4 – 4.0) of castor oil (ASTM 2002).Table six Fatty acid composition of fatty acid of brebra oil (FAs = fatty acids)No 1 two three 4 5 Fatty acids Unsaturated FAs Oleic Linoleic Linolenic Arachidonic Eurcic Total Saturated FAs 6 7 8 9 Palmitic Stearic Arachidic Behenic Total C16:0 C18:0 C20:0 C22:0 7.2 1.9 3.three 6.9 19.three C18:1 C18:2 C18:three C20:4 C22:1 0.6 48.2 27.7 0.8 three.4 80.7 Carbon quantity Quantity ( )The low saponification value and acid value imply that the oil is much more proper for biodiesel since the oil acid value for biodiesel, that is significantly less than 1 . The iodine value of brebra oil was 104.48 gI2100 gm (within the range, 100-120 gI2100 gm, of DIN) which can be greater than the array 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 84.8 gI2100 gm refined castor oil (Akpan et al. 2007). One the other hand, the iodine value of this study was reduced than the selection 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 given 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 cash.
