And palm kernel oil (247 mg KOH gm) (Pearson, 1976). However, this saponification value is within precisely the same array of some edible oils reported by Eromosele and Paschal (2002). Additionally, saponification worth (174.95) of your oil in this investigation is virtually inside the range of (17587) ASTM (2002) specification for oils. In accordance with Pearson (1976), oils with reduce saponification values include higher volume of extended chain fatty acids. Therefore, the value obtained for brebra seed oil contained high quantity of larger fatty acids (because it is presented on Table six, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, 3:298 http:springerpluscontent31Page six ofTable five Brebra oil chemical and physical characteristicsOil mAChR2 Purity & Documentation physicochemical qualities Colour Density at 20 Precise gravity at 20 Kinematic Viscosity at 40 Acid worth pH worth Saponification value Refractive index at 40 Iodine value 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.gI2100 gm mEqKg104.48 six.88 174.chain accounts 92.8 ). The worth of viscosity of brebra oil was 40.49 mm2s (as mentioned above) is identified to become significantly less than the viscosity of cashew nut oil (56 mm2s) (Akinhanmi et al. 2008). For production of biodiesel, therefore, transesterification reaction could be the very best process to reduce the viscosity from the oil. The oil under 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 (47.6 ) by Ohsodi (1992). The acid value in this oil is under the maximum limit (two.0 mg KOHg) of DIN EN ISO 660 and nearly 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 2 three four five Fatty acids Unsaturated FAs Oleic Linoleic Linolenic Arachidonic Eurcic Total Saturated FAs six 7 eight 9 Palmitic Stearic Arachidic Behenic Total C16:0 C18:0 C20:0 C22:0 7.two 1.9 three.three 6.9 19.three C18:1 C18:two C18:3 C20:four C22:1 0.six 48.two 27.7 0.8 three.4 80.7 Carbon number Quantity ( )The low saponification worth and acid worth imply that the oil is more acceptable for biodiesel because the oil acid value for biodiesel, which is significantly less than 1 . The iodine worth of brebra oil was 104.48 gI2100 gm (inside the variety, 100-120 gI2100 gm, of DIN) which is greater 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 one hundred gm palme stearine, 500 gI2100 gm tallow, 600 gI2100 gm lard, (http:dec2.tec.agrar.tu-muenchen.de pflanzoelrkstandarde.html) 44.4 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 particular the other hand, the iodine value of this study was decrease than the array of 11015, 12535, 12540, and 11524 gI2100 gm worth of LTB4 manufacturer rapeseed oil, sunflower oil, soybean oil and corn oil, respectively. The oil in this study is considered drying oil given that drying oils have an iodine value above 100 gI2100 gm (Duel and Tr 1951). The peroxide value of brebra oil was 6.88 mEqKg. It was higher than the peroxide worth of three.1 mEqKg of cash.
