摘要
以二甲亚砜为原料,亚硫酸氢钠为还原剂合成食用香料二甲基硫醚。产物的红外光谱、1~H-核磁共振谱和折光率表明该产物具有预计结构和较高纯度,评香结果表明该产物香气纯正。讨论了以亚硫酸氢钠为还原剂的可能的反应机理。实验结果表明这是一条合成食用香料二甲基硫醚的经济可行的路线。
The edible perfume material methyl-sulfide is prepared from methyl-sulfoxidein the presence of a reducing agent sodium bisulfite. The product is identified by IR spectra. ~1H-NMR and no, which shows the product possesses prospective structure and high purity. Odor-evaluating proves that it has pure odor. This paper also discusses the possible reac-tion mechanism by using sodium sulfite as reducing agent. The experimental resuit makes it clear that it ia an economical, convenient route to synthesis methyl-sulfide.
