TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compounds: The caustic metallic base is sodium hydroxide or potassium hydroxide, preferably anhydrous sodium hydroxide.The amount of sodium hydroxide added into the oil is 3-10 g of sodium hydroxide per liter of oil, preferably 4-8 g of sodium hydroxide per liter of oil, more preferably 6.25 g of sodium hydroxide per liter of oil.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The water contained in the oil is evaporated by heating the oil prior to processing.The alcohol is methanol or ethanol.The amount of alcohol added into oil is in volume ratio of 1:8-1:3, preferably 1:5-1:3, more preferably 1:4.The sodium hydroxide and alcohol are mixed together before adding into the oil, such that an alcoholic catalyst (18) is formed. The sodium hydroxide is completely solubilized in the alcohol.Preferred Process: Ether, glycerine or other contaminating triglycerides compounds produced during manufacturing process is removed by allowing the compounds to settle in a settling tank, before draining out glycerine or biofuel from the settling tank.The removal of glycerine or triglyceride compound (22) is repeated to remove further contaminants such as glycerine, ether or triglyceride compounds.The initial catalyzation process is carried out using at least half of the specified amount of alcoholic catalyst, preferably 1/2 to 4/5 of alcoholic catalyst, more preferably 2/3 to 3/4 of alcoholic catalyst, most preferably 2/3 of alcoholic catalyst is added to oil in initial catalyzation process and the remaining 1/3 of alcoholic catalyst is added to secondary refining process.The alcoholic catalyst is added under pressure using a sparger to ensure sufficient dispersal of alcoholic catalyst through the oil. The mixture after addition of alcoholic catalyst is mixed or stirred for 5-60 minutes, preferably 10-30 minutes, more preferably 20 minutes.The mixing of reaction mixture is performed by heat-stirring in order to accelerate catalyzation.The mixture of biofuel, alcohol and caustic base is heated to 40-110 degrees C, preferably 50-60 degrees C, and then kept at room temperature. The removal of alcohol from mixture of biofuel, alcohol and caustic base is performed by distillation.The mixture of biofuel, alcohol and caustic base is allowed to settle for 0.5-48 hours, preferably 24 hours or more to facilitate removal of glycerine or contaminating triglyceride compounds.The biofuel is washed with water, before and after removing glycerine, ether or triglyceride compounds.The biofuel is washed with water in ratio of 70-30% (v/v), preferably 60-40% (v/v), more preferably 50% or more.The water is bubbled through the biofuel using aeration device such as airstone or any other suitable aeration device.The water si sprayed as a fine mist over the surface of biofuel, and allowed to pass through the biofuel.The pH of biofuel is adjusted to 7 using acidified water, or by adding acetic acid to water.The desired amount of acetic acid is added to the water in order to reduce the pH of water by the same number of pH value less than 7, the pH of biofuel is more than 7. The oil is provided in the form of wax.The oil is an oil or wax obtained from feedstocks chosen from babassu, castor, cottonseed, crabe, linseed, olive, palm, peanut, safflower, high-oleic safflower, sesame, soybeans, canola, corn, sunflower seed, rapeseed, coconut, mango, mustard, palm oil, hemp, algae, oilseeds, vegetable oil, waste vegetable oil, cooking oil, trap grease, animal tallow or fats and any other form of animal or natural plant oil or fats.The oil is fresh or used oil, and the biofuel is a biodiesel.The glycerine or triglyceride compounds are separated from the biofuel and refined, to obtain glycerine or triglyceride compound.
