Effect of stirring speed and reaction time on sunflower biodiesel production [electronic resource].

Includes references.

Biodiesel was produced from sunflower oil using methyl alcohol at a ratio of 22.5% (v/v) to the oil and sodium hydroxide as a catalyst at a ratio 5.5 g per 1 liter oil. The production of biodiesel was carried out under four stirring speeds: 250, 500, 750 and 1000 rpm and for each stirring speed, five reaction times were used: 10, 20, 30, 40 and 50 min. the research concluded to that: 1- the optimum stirring speed for the production of biodiesel from sunflower oil is 750 rpm. 2- the optimum reaction times are 40 and 50 min. 3- the highest biodiesel production is 98% and was obtained at 50 min time of reaction for each of the two speeds of stirring: 500 and 750 rpm and at 10 min time of reaction under the speed 10 rpm. 5- the use of sodium hydroxide as a catalyst for the production of biodiesel from sunflower oil at a concentration of 3.5 g per liter of oil results in an excess soap in the produced biodiesel and a loss of biodiesel in the washing water.
