[Abstract]
3,3,6,6-Tetrabenzyl-1,2,4,5-tetrathiane was prepared in solvent mixture of ether and water using 1,3-diphenyl-2,2-dithiol as raw materials and the yield of this new flavor reached 50.3%. Moreover, the thermal properties of 3,3,6,6-tetrabenzyl-1,2,4,5-tetrathiane were studied by DSC and TG method. The heating temperature ranged from 50 ℃ to 500 ℃ at a rate of 10 ℃/min. The results showed that it should be preserved below 312 ℃ as it can be oxidized over 312 ℃ in air. Besides, this flavor was found to be suitable for soup seasoning rather than barbecue.
