Esterifikasi Asam Stearat Dengan Gliserol Menggunakan Katalis Nades (Natural Deep Eutectic Solvent) Dari Betain Hidroklorida Dan Fruktosa

ABSTRACT
An emulsifier or emulsifying agent is a material that can unite two compounds of different
polarities. Mono diacylglyceride (MDAG) is a synthetic emulsifier that can be obtained
from the esterification reaction of fatty acids with glycerol using NADES (Natural Deep
Eutectic Solvent) catalyst. NADES is an environmentally friendly organic solvent made
from a mixture of HBA (Hydrogen Bond Acceptor) and HBD (Hydrogen Bond Donor)
which form a eutectic phase with a melting point is lower than its constituent
components. In this study, NADES was formed using betaine hydrochloride as HBA and
fructose as HBD. This study aims to determine the physical and chemical properties of
NADES (density, viscosity, pH, and FTIR), to determine the effect of reaction temperature
and catalyst weight on the conversion of the esterification reaction. NADES was
prepared with a 1: 2 mole ratio of HBA and HBD at 80oC with a stirring speed of 200
rpm. The esterification reaction was carried out for 3 hours, the mole ratio of stearic
acid: glycerol was 1: 6, with a stirring speed of 400 rpm, temperature variations (120oC,
150oC, and 180oC), and the amount of NADES catalyst (1, 3, 5% by weight of stearic acid
based). The composition of MDAG results from this study was determined based on the
GC-MS test. NADES has a pH of 2.30 with a density of 1.187 cP and a viscosity of 0.218
cP. The conversion reaction increases with increasing temperature and catalyst weight.
In this study, the highest conversion reaction was obtained at the optimum conditions, at
180oC using 5% catalyst weight. GC-MS test results showed the presence of DAG of
11.61%.
Keywords: betain hydrochloride, esterification, FTIR, GC-MS, NADES.
