【摘要】 以对甲苯磺酸为催化剂,中间体二苄基二硫醇和对二甲氨基苯甲醛为原料,无水乙醇为溶剂,合成了新型香料2,2-二苄基-4,6-二(对二甲氨基)苯基-1,3,5三硫环己烷,产率为71.0%,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(对二甲氨基)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(对二甲氨基)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0.28×10-6~0.39×10-6,在植物油中为13.85×10-6~16.55×10-6。更多还原

【Abstract】 2,2-bibenzyl-4,6-bi(p-)dimethylaminophenyl-1,3,5-trithiane was prepared in solvent ethanol,1,3-diphenyl-2,2-dithiol and dimethylaminobenzaldehyde as raw materials,using p-toluenesulfonic acid as catalyst,the yield of 2,2-bibenzyl-4,6-bi(p-)dimethylaminophenyl-1,3,5-trithiane was 71.0%,and the structure of the product was Characterized by IR,1H NMR and MS.The odour of the product was identified,the result showed that it’s odour is intense onion and garlic fragrance.The threshold of 2,2-bibenzyl-4,6-bi(p-)dimethylaminophenyl-1,3,5-trithiane is 0.28×10-6～0.39×10-6 in water and 13.85×10-6 ～16.55×10-6 in vegetable oil.更多还原
