Abstract

Glycerol is one of the important chemicals in industry, especially the pharmaceutical industry, foodstuff, cosmetics, explosives, and others. Glycerol can be obtained by careful evaporation, and then purified by distillation at reduced pressure. Glycerol is soluble both in water and insoluble in eter. Glycerol can be useful for us to synthesis of fat in the body. Glycerol can be obtained from several processes, including the process of refining oil and fat, alcoholysis, enzymatic, hydrolysis and saponification of oils and fats. This experiment aims to determine the best separation process which can be used to obtain glycerol with variations in rotation speed centrifugation. The experimental procedure begins with the process of palm oil hydrolysis using KOH catalyst then glycerol formed is separated using methods sentrifugasii with their speed - respectively 1090, 1375 and 1772 rpm. From the experimental results obtained at the highest glycerol separation process with speed rrpm 1772 as many as 3.5 mL. Separation using centrifugation method when compared with other methods of separation which is the best method. This is because the results obtained are more separation than others.
