摘　　要：以 0 .1 mol乙缩醛和 0 .1 mol正丙硫醇为原料 ,35℃下在四氯化碳中反应 ,经红外光谱 ,色谱 ,质谱 ,元素分析以及核磁共振谱检测 ,确证了产物为乙醛正丙硫醇缩醛 .产率为 72 % .产品含量为 99.7% .In the presence of carbon tetrachloride(30 mL). Acetaldehyde(0\^1 mol) was treated with n propylthiol(0\^1 mol) at 35 ℃ for 20 min to yiled 72% acetaldehyde propyl mercaptal. The synthesis of this thioacetal was reported. And the structure of this product was proved by way of IR spectrum, 1HNMR spectrum datum. The crude product thus obtained was distilled to 99\^7%.
