Ge from 1.475 to 1.485 (Duel and Tr 1951). The saponification worth of your oil within this study was 174.95 mg KOH/gm. This was decrease than the values for some frequent oils like castor seed oil (185.83) (Akpan et al. 2007), palm oil (196-205 mgKOH/g), groundnut oil (188-196 mgKOH/g), corn oil (187-196 mgKOH/g) as reported by Akinhanmi et al. (2008), coconut oil (253 mg KOH/gm) and palm kernel oil (247 mg KOH/ gm) (Pearson, 1976). Even so, this saponification value is within the same array of some edible oils reported by Eromosele and Paschal (2002). Additionally, saponification value (174.95) on the oil in this investigation is pretty much within the selection of (17587) ASTM (2002) specification for oils. Based on Pearson (1976), oils with decrease saponification values include high amount of lengthy chain fatty acids. Consequently, the value obtained for brebra seed oil contained higher quantity of greater fatty acids (since it is presented on Table 6, fatty acids 18 carbonAndualem and Gessesse SpringerPlus 2014, 3:298 http://www.springerplus/content/3/1/Page six ofTable five Brebra oil chemical and physical characteristicsOil physicochemical qualities Colour Density at 20 Precise gravity at 20 Kinematic Viscosity at 40 Acid worth pH value Saponification value Refractive index at 40 Iodine worth Peroxide value Ester valueAll values are mean worth of triplicates.Unit Kg/m3 kg/l mm2/s mg KOH/gValues Pale-yellow colour limpid liquid 0.942 0.926 40.59 0.39 6.mg KOH/g174.95 1.gI2/100 gm mEq/Kg104.48 six.88 174.chain accounts 92.eight ). The value of viscosity of brebra oil was 40.49 mm2/s (as described above) is discovered to be significantly less than the viscosity of cashew nut oil (56 mm2/s) (Akinhanmi et al.Clemastine-d5 Autophagy 2008). For production of biodiesel, hence, transesterification reaction could be the greatest system to cut down the viscosity with the oil. The oil below investigation has really low acid value of 0.39 mg KOH/g when compared with cashew nut oil (0. 82 mg KOH/g) (Aremu et al. 2006), refined castor oil (0.869) and crude castor oil (1.148) (Akpan et al. 2007), plukenetia conophoora (11.5 mg KOH/g) as reported by Akintayo and Bayer (2002), aenniseed (47.six ) by Ohsodi (1992). The acid value in this oil is beneath the maximum limit (two.0 mg KOH/g) of DIN EN ISO 660 and nearly within the range 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 2 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:four C22:1 0.6 48.two 27.7 0.eight 3.four 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, which can be much less than 1 .Prodigiosin custom synthesis The iodine value of brebra oil was 104.PMID:23291014 48 gI2/100 gm (inside the variety, 100-120 gI2/100 gm, of DIN) which is greater than the array of 774 gI2/100 gm olive oil, 80 gI2/ 100 gm coconut oil, 128 gI2/100 gm palm kernel, 4458 gI2/100 gm palm oil, 855 palme oleine, 205 gI2/ 100 gm palme stearine, 500 gI2/100 gm tallow, 600 gI2/100 gm lard, (http://dec2.tec.agrar.tu-muenchen.de/ pflanzoel/rkstandarde.html) 44.four gI2/100 gm cashew nut oil (Aremu et al. 2006), 38.1 gI2/100 gm citrullus vulgaris (Achinewhu 1990), Hausa melon seed oil (38.50 gI2/100 gm) (Oladimeji et al. 2001) and 84.eight gI2/100 gm refined castor oil (Akpan et al. 2007). 1 the other.
