KAJIAN AWAL PENGARUH WAKTU REAKSI DAN RASIO MOLAR ASAM OLEAT DENGAN BUTANOL TERHADAP SIFAT FISIKO KIMIA PLASTISIZER BUTIL OLEAT
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 esearch is
the molar ratio of 1:12, reaction time 12 hours resulted in a conversion
reaction of 76.73%.
