Esterifikasi Asam Palmitat Dengan Gliserol Menggunakan Katalis Nades (Natural Deep Eutectic Solvents) Dari Campuran Betain Hidroklorida Dan Sukrosa

ABSTRACT
Monoglycerides (MG) and diglycerides (DG) are a group of synthetic emulsifiers that
can be obtained from the esterification of fatty acids with glycerol using deep eutectic
solvents (DES) as catalysts. DES is a system consisting of a mixture of at least two
components, namely hydrogen bond acceptors (HBA) and hydrogen bond donors
(HBD) which form a eutectic phase with a lower melting point than the constituent
components. This study aims to synthesize and characterize the physical chemical
properties of NADES from a mixture of betaine hydrochloride and sucrose (density,
viscosity, pH, and FT IR) and determine the effect of NADES catalyst through
reaction temperature, catalyst weight on the reaction conversion. NADES is formed
from a mixture of betaine hydrochloride and sucrose at a temperature of 80oC with a
stirring speed of 400 rpm at an HBA / HBD molar ratio of 1/1. The esterification
reaction of palmitic acid with glycerol takes place with a molar ratio of 1/6, stirring
speed of 300 rpm, temperature of 120-180 oC and a catalyst weight of 1-5% based on
palmitic acid. The composition of MG and DG was determined by GC-MS. The
conversion increases with increasing temperature but decreases with the addition of a
catalyst. The highest conversion reaction at 180 oC was using a 1% -weight catalyst,
which was 94.78%. In this condition, DG is obtained with a composition of 25.9% in
the emulsifier product.
Keywords: fatty acids, emulsifier, esterification, conversion reaction, NADES
