Abstract

Estolide 2-ethylhexyl ester synthesized through condensation reaction between ricinoleic acid from castor oil (Ricinus communis) and lauric acid, and then capped with 2-ethylhexyl alcohol. The reaction was continuously conducted under vacuum for 24 hours. Product of 2-ethylhexyl ester was characterized by using Fourier Transform Infrared (FTIR) to determine functional group and Nuclear Magnetic Resonans (NMR) for structure's determination. The presence of ester group at 1738.23 cm-1 wavenumber indicates that the formation of estolide ester has occurred. The vibration peak of C-O at 1174.60 cm-1 and 1117.10 cm-1 support the formation of ester. The presence of CH2 bending indicated the long-chain compound. The ester methine signal at 3.8669 ppm indicated the estolide linkage in the 1H-NMR spectrum while the13C-NMR showed two carbonyl signals at 173.41 ppm for acid and 173.56 ppm for ester.
