PENGARUH WAKTU REAKSI DAN RASIO MOL ASAM LINOLEAT DENGAN ISOPROPANOL PADA SINTESA PLASTISIZER ISOPROPIL LINOLEAT
ABSTRACT: Diversity of palm
oil product in Indonesia is still limited, therefore it is needed to take an advantage
of the development of downstream product of crude palm oil by esterification reaction.
Esterification reaction is a reaction between carboxylic acid and alcohol to
form ester. One of the emerging downstream product fatty acid alkyl ester is
plasticizer. Plasticizer is an additive compound added to polymer to improve
flexibility and workability. The purpose of this research was conducted to
study the effect of reaction time and mole ratio and identify product of
plasticizers isopropyl linoleic. In this research, plasticizer was synthesized
by esterification of linoleic acid and isopropanol, using activated natural
zeolite catalyst. The process was done with a variation of reaction time (4, 6,
and 8 hours) and mole ratio (1: 6, 1: 9, and 1:12), with reaction temperature
at 80 °C, stirring speed at 200 rpm and 15% of composition of linoleicacid
based catalyst as fixed variables. From the analysis of the results showed that
the esterification reaction time and mole ratio affect the product conversion.
The best operating condition obtained in this research was 4 hours of reaction
time and 1:12 of mole ratio which resulted the conversion of reaction was
67.09%. Characteristics of plasticizer produced fromthis research were
viscosity (at 20 °C) 2.405 to 2.803 mPa.s and Specific Gravity (at 20 °C) from
0.863 to 0.872.
