【摘要】 以ZnO-Al₂O₃为催化剂,探讨了各种因素对反应结果的影响,提出了适宜的反应条件:ZnO-Al₂O₃催化剂中含Al₂O₃40％,常压,反应温度450—475℃,空速1000—2000小时^-1,氨醛比1.3:1（摩尔比）。异丁腈收率达91％以上。经精制,异丁腈的纯度达98％以上。更多还原

【Abstract】 Factors influencing the results of the reaction were investigated.The suitable reaction conditions were:ZnO-40％ Al₂O₃;atmospheric pressure;reaction temperature,450—475℃;space velosity,1500—2000hr^-1;ammonia/isobutyraldehyde mol ratio,1.3:1.The yield of isobutyronitrile was higher than 91％ under the above conditions. After distillation, the purity of isobutyronitrile was higher than 98％.更多还原
