摘　　要：采用合成氨厂的氨合成气代替纯氢气使脂肪腈加压催化氢化 ,可一步制得双脂肪烃基仲胺。采用该工艺制得的仲胺产品质量技术指标为 :w(仲胺 ) =92 % ,w(叔胺 ) <3% ,总胺值 =110mgKOH/g ,达到美国Kemanines - 970和日本FarminB62等同类产品水平。Fatty sec-amines can be directly prepared by catalytic h ydrogenation of fatty nitriles,using ammonia synthesis gas instead of pure hydro gen.Major qualities of the sec-amines produced by the new processes were w (sec-amines)=92%,w(tert-amines)<3%,total amines=110 mgKOH/g ,comparable to the similar products prepared by the conventional processes,for e xa mple (USA)Kemanines-970 and (Japan)Farmin B62.Experiment showed that this new pr ocess has many advantages such as simple procedure,save of investment,lower cost,etc.
