2,2-二苄基-4,6-二苯基-1,3,5三硫环己烷的合成及香气研究

Study on the Synthesis of 2,2-Bibenzyl-4,6-Biphenyl-1,3,5-Trithiane and its Odou

摘要:

以对甲苯磺酸为催化剂，中间体二苄基二硫醇和苯甲醛为原料，无水乙醇为溶剂，合成了新型香料2,2-二苄基-4,6-二苯基-1,3,5三硫环己烷，产率为63.0%，用IR，1H NMR和MS证实了目标化合物结构，并对2,2-二苄基-4,6-二苯基-1,3,5三硫环己烷的香气进行了鉴定，结果表明2,2-二苄基-4,6-二苯基-1,3,5三硫环己烷具有浓郁的葱蒜气味，其阈值在水中为0.2210-6~0.3710-6 mol/L,在植物油中为1210-6~15.3310-6 mol/L。

Abstract:

A novel spice, 2,2-bibenzyl-4,6-biphenyl-1,3,5-trithiane, was synthesized using ethanol, 1,3-diphenyl- 2,2-dithiol and FeCl3 as raw materials and p-toluenesulfonic acid as catalyst. The yield of the product was shown to be 63.0% and its structure was characterized by IR, 1H NMR and MS. Besides, the odour of the product was identified, which is similar to onion and garlic fragrance with the thresholds being of 0.2210-6~0.3710-6 mol/L in water and 1210-6~15.3310-6 mol/L in vegetable oil.
