摘　　要：癸酸与氯化亚砜反应后再胺化得癸酰胺,癸酸与氯化亚砜的摩尔比为1∶1.24,此步总收率为89.5%;癸酰胺在不同脱水试剂的作用下,脱水生成癸腈,癸酰胺与脱水试剂的摩尔比为1∶1,得到在三氟甲磺酸酐作用下脱水,最好收率为95%。Capric acid was reacted with thionyl chloride and then ammonified to get capric acid amide,n（capric acid）∶n（thionyl chloride）=1∶1.24,the whole yield was 89.5 %;capric acid amide was dehydrated by different kinds of dehydrating agents to get capric nitrile,n（capric acid amide）∶n（dehydrating agent）=1∶1,the best dehydrating agent was trifluoromethanesulfonic anhydride,the best yield was 95 %.
