【Abstract】 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%.更多还原
