General Description
3-(Methylthio)-1-propanol is a volatile sulfur flavor compound mainly found in wine and soy sauce.
Synthesis
3268-49-3
505-10-2
An excess of 10% sodium borohydride (NaBH4), a reducing agent, was slowly added to 30 mL of the selected solvent at 0°C to form a suspension. Subsequently, 10 g of 3-methylthiopropionaldehyde (MMP) was slowly added dropwise to the above suspension at a temperature controlled below 20 °C. After the dropwise addition, the reaction mixture was stirred at room temperature for 3 to 12 hours. Upon completion of the reaction, HCl solution was added to the reaction solution for hydrolysis. After hydrolysis, water was removed from the reaction solution by evaporation under reduced pressure. The reaction solution was filtered to remove the sodium chloride generated by hydrolysis and the residue was washed with 10 mL of cold methanol solution to further extract the product 3-methylthiopropanol. Finally, methanol was removed by evaporation of the combined mixed solution and filtrate to give pure 3-methylthiopropanol. Note: The solvent may be selected from dichloromethane (CH2Cl2), dimethylformamide (DMF), methanol, 3-methylthiopropanol (or a solvent mixture thereof with a diluent, referred to as "3-methylthiopropanol"), tetrahydrofuran (THF), or water (H2O), and the concentration of 3-methylthiopropanal (MMP) is 100 percent .
