And palm kernel oil (247 mg KOH gm) (Pearson, 1976). However, this saponification worth is within the identical range of some edible oils reported by Eromosele and Paschal (2002). Furthermore, saponification worth (174.95) with the oil within this investigation is nearly within the range of (17587) ASTM (2002) specification for oils. According to Pearson (1976), oils with lower saponification values include high amount of lengthy chain fatty acids. Therefore, the worth obtained for brebra seed oil contained high quantity of higher fatty acids (as it is presented on Table six, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, 3:298 http:HDAC1 custom synthesis springerpluscontent31Page 6 ofTable five Brebra oil chemical and physical characteristicsOil physicochemical traits Colour Density at 20 Particular gravity at 20 Kinematic Viscosity at 40 Acid value pH value Saponification value Refractive index at 40 Iodine value 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 six.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 described above) is discovered to become much less than the viscosity of cashew nut oil (56 mm2s) (Akinhanmi et al. 2008). For production of biodiesel, hence, transesterification reaction will be the greatest technique to reduce the viscosity of the 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 (11.5 mg KOHg) as reported by Akintayo and Bayer (2002), aenniseed (47.six ) by Ohsodi (1992). The acid worth within this oil is under the maximum limit (2.0 mg KOHg) of DIN EN ISO 660 and nearly inside the array of ASTM specification (0.four – 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 five 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.two 1.9 three.3 6.9 19.3 C18:1 C18:two C18:3 C20:4 C22:1 0.6 48.two 27.7 0.8 3.4 80.7 Carbon number Quantity ( )The low saponification value and acid value imply that the oil is additional suitable for biodiesel because the oil acid worth for biodiesel, that is less than 1 . The iodine worth of brebra oil was 104.48 gI2100 gm (inside the range, 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) (HDAC3 Synonyms 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 reduce 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 as drying oil due to the fact drying oils have an iodine worth above 100 gI2100 gm (Duel and Tr 1951). The peroxide value of brebra oil was six.88 mEqKg. It was higher than the peroxide value of 3.1 mEqKg of money.
