【Abstract】 1-Ethoxyl 1 butylthiopropane,1 ethoxyl 1 sec butylthiopropane,1 ethoxyl 1 amylthiopropane and 1 ethoxyl 1 furfurylthiopropane were synthesized by the reaction of propanal diethyl acetal with butyl mercaptan,sec butyl mercaptan,amyl mercaptan and furfuryl mercaptan,respectively,in carbon tetrachloride at room temperature for 20 min.The solvent was distilled at reduced pressure except for the synthesis of 1 ethoxy 1 amylthiopropane,where the solvent was distilled at normal pressure.The yields were 40%,23%,37% and 60%,respectively.Mercaptal were not detected in the products except in 1 ethoxyl 1 amylthiopropane.Structures of the four compounds were identified by IR,GC MS, 1HNMR and the analysis of sulfur content.更多还原
