METODE DISTILASI VAKUM UNTUK PEMBUATAN MINYAK JERUK PURUT DENGAN MENGGUNAKAN AIR SEBAGAI PELARUT (Vacuum Distillation Methode in Producing Lime Oil Using Water as the Solvent)

Abstract

Vacuum Distillation is a process of separation of two kompenen a very high boiling point, motede used is by lowering the surface pressure is lower than 1 atm, also allows for a low boiling point, in the process temperature used to perform distillation need not be too high. Vacuum distillation is operated at a pressure of less than 1 atm in order to, avoid the occurrence of oxidation reactions of components will be separated for the double bond in the compound is not broken. This lab using vacuum distillation. The working principle of this tool is based on the phenomenon of vacuum under 1 atm for lower boiling point solvent that contained lime oil components are not damaged and the time required for distilled lime oil faster. Solvents used were water. Water use is based on reason is more economical. The function of the solvent dissolves the oil component is contained lime then evaporate along with water. After that the mixture between oil and water are separated using a separator funnel. From the results of our analysis that lime oil has a good quality lab. It is seen from the density (0.860 g / ml), the refractive index (1.464), acid number (1,801) and saponification (3.92) in the range of Essential Oil Association. Sucrose content – average 0,208% lime oil.
