Synthesis of Flavor 3-Methylthiopropionaldehyde Diethyl Acetal

Abstract:

3-Methylthiopropionaldehyde diethyl acetal was synthesized from the reaction of 3-methylthiopropional with ethanol and triethyl orthoformate. The effecting factors including the kinds of catalyst, the mole ratio of raw materials, the amount of catalyst and the reaction time were optimized. The structure of product was characterized by gas chromatography, infrared spectroscopy, mass spectrometry, and nuclear magnetic resonance. Additionally, the mechanism of the reaction was speculated; the odor characteristics were evaluated.
