Abstract: Two flavoring agents 1-methylthio-2-propanone and 1-n-butylthio-2-propanone were synthesized by the reaction of sodium hydroxide and chloroacetone with exess amount of methyl mercaptan and butyl mercaptan respectively. The yields was 66.4% and 78.4% in turn (based on the amount of chloroacetone). Structure of the target compounds was identified by means of elemental analysis, FTIR, 1 H NMR and GC-MS date.

Key words: 1-methylthio-2-propanone, 1-n-butylthio-2-propanone, flavoring compounds, synthesis
