..., and symmetrical vibration of the O-H bond which is characteristic of glucoside ring. The chromatogram identified seven compounds linked to a functional group with the major constituent being 9-octadecenoic acid methyl ester at a peak of 63.52 %, indicating that fatty acids are the dominant constituents...

... was achieved at varied temperature of 50-60 o C and the catalyst concentration between 0.5-2.0 wt% at constant reaction time of 1 hour 30 minutes after which the mixture was allowed to settle and the methyl ester (biodiesel) was separated from the mixture. The characterization of desert date seed oil methyl...

..., the reaction was heated and stirred on the magnetic heating stirrer for 2 hours at a temperature of 170 °C. The heated mixture was allowed to cool before separating the glycerol from the methyl ester produced on a separating funnel. The methyl ester was heated to remove the remaining methanol that may have...

... impact. They are non-biodegradable and highly toxic, thus leading to high cost of wastes treatment. A benign and biodegradable OBM was formulated from sweet almond seed oil (SASO) using Soxhlet Extraction Method. The SASO base oil was converted to SASO methyl ester through the process...

... Abstract In this research, bio-lubricant was produced from castor oil in two stage processes where methyl ester of the oil was produced by esterification and then transesterified using homogenous catalyst (NaOH). It was then blended with 15w/w% of Sodium Lauryl Sulphate (SLS) to produce bio...
