| Abstract: | Three 1,3-oxathiolane were synthesized by the reaction of mercaptoethanol with 2-butanone,2-pentanone and 2-hexanone under focused microwave irradiation in the presence of p-toluenesulfonic acid as catalyst. The yields were 67.3%, 71.9% and 65.6% respectively. Structures of three flavoring compounds were identified by the data of GC, IR, elemental analysis and GC-MS spectra. The odor characteristics of three flavoring compounds were evaluated. |
