Abstract
High supply of crude pump oil in Indonesia has created many opportunities for downstream industry on palm oil industry. One of alternatives for this downstream palm oil industry is esterification of oleic acid that contained in crude palm oil. The purpose of this research are to make isobutyl oleic by esterification of oleic acid and isobutanol using H-Zeolit as the catalyst, to determine mixing speed and variation composition catalyst that produce highest reaction conversion, to compare physic attributes among the product. In this research, the variation of mixing speed were 150 rpm, 175 rpm, 200 rpm, 225 rpm and 250 rpm and the composition catalyst were 5%, 10%, and 15% of based sample reactant. With fixed variable are reaction temperature 100 oC, time reaction 5 hours and compare between oleic acid and isobutanol 1:6. Catalist H-Zeolit, oleic acid and isobutanol reacted at batch reactor with agitation as long 5 hours. From product analysis showing that mixing speed and composition catalyst affect the product conversion reaction. The best operation condition is at mixing speed is 200 rpm and composition catalyst 15% that produce 56.44% reaction conversion. The physical and chemical properties from the product meet the commercial raw material of plasticizer.
