Abstract

In the laboratory scale, the effect of the concentration of H2SO4 catalyst (1.25-6.25) (% w/w) and the equivalent mol ratio between lauric acid and glycerol (1:1; 1:2.5; 2.5:1) on the synthesis of α-monolaurin has been studied. The α-monolaurin compound has been synthesized from lauric acid and glycerol was done by batch esterification on the free solvent system. The esterification by using 5% H2SO4 catalyst and equivalent mol ratio between lauric acid and glycerol 1:2.5 produced most monolaurin, and dilaurin in amount of 31.14 and 4.42%, respectively. The monolaurin and dilaurin are identified by thin layer chromatography (TLC), infrared spectrophotometer (FTIR), liquid chromatography-mass spectrometer (LC-MS), and Nuclear Magnetic Resonance (NMR) spectrometer. The spectral data of monolaurin was compared to spectral data of standard α-monolaurin
