Abstract:In order to increase the varieties of our country's perfume, the preparation of dipropyl disulfide with rich fragrance of onion and garlic is studied by the reaction of n-propyl bromide with sodium disulfide. The structure of the product is confirmed by IR and NMR. The reaction is improved in the presence of phase tranfer catalyst tetrabutyl ammonium bromide. The ratio of two reactant and the quantity of the catalyst are examined. The yield is about 82. 0 %.
Keywords:perfume  dipropyl disulfide  phase transfer catalysis
