KAJIAN AWAL PENGARUH WAKTU REAKSI DAN RASIO MOLAR ASAM OLEAT DENGAN BUTANOL TERHADAP SIFAT FISIKO KIMIA PLASTISIZER BUTIL OLEAT
Abstract
Vol 7 No 2 ABSTRACT Esterification reaction is a reaction between fatty acids or carboxylic acids with alcohols to esters. Fatty acid (oleic acid) sourced from palm oil. One alternative to increase the economic value of palm oil is oleic acid esterification into oleic butyl known as plasticizers. Plasticizer additives are compounds added to polymers to improve its flexibility and workabilitas. This study aims to study the effect of reaction time and molar ratio of the plasticizer synthesis oleic butyl and identify the plasticizer oleic butyl. In this study, the first step is preparation H-Zeolite catalyst, then synthesis of plasticizer butyl oleic esterification using natural zeolite catalysts were activated to H-zeolites with variables in the reaction time (6, 9 and 12 hours) and the molar ratio of oleic acid and butanol (1: 6, 1: 9 and 1:12) with the permanent variable stirring speed of 200 rpm, 108-112 ° C of temperature and the catalyst were 15% oleic acid-based. From the test results obtained 0.862 specific gravity, viscosity of 8.39 mPa and showed that the specific gravity and viscosity of the resulting plasticizer has commercial plasticizer standard namely 0.862 to 0.928 and from 8.2 to 9.4. Optimal operating conditions obtained in this research is the molar ratio of 1:12, reaction time 12 hours resulted in a conversion reaction of 76.73%.
