Identification of Patchouli–Chemical Properties on Oil Purification by Using Acid-Activated Bentonite

Abstract

This research is aimed at obtaining –oil chemical properties on purification that include solubility in alcohol, total acid, total ester, Fe Content, Patchouli Alcohol Content, Alpha Copaene (C₁₅H₂₄) Content, and purity. The method of research used is Complete Randomized Design (CRD) with factorial design. Two factors has been examined are 1) bentonite activations wit 3 levels; inactivated bentonite, H₂SO₄-activated bentonite, and HCl-activated bentonite; and 2) the number of bentonite applications wit 5 levels : 1%, 2%, 3%, 4%, and 5%. And analysis of oil coloris made by using UV spectropotometer to see clearness or its transmittance percentage. Acid –activated bentonite by number of bentonite given affects ethanol solubility, total acid, total ester, Fe content, Alpha copaene content, and patchouli alcohol content. H₂SO₄ –Activated bentonite by 2% given was indicated as te best result by increasing percentage of transmittance from 69% to 81,550%, ethanol solubility 4,050%, total acid 2,120, total ester 7,975,  Alpha copaene content 0,04%, Patchouli alcohol content 25,02%, and Fe content 5,864 mg/kg.
