新的活性最高的阮来铜催化剂的制备,是将60%A1-40%Cu合金用氢氧化钠溶液先在0～10℃消解,继續在90℃消解45分钟。它的活性约为正常阮来镍的70%。它的氢化催化活性的减弱与时间成正比。在5个月后,活性仅减少1/3。在127℃时氢化的相对速率为丁腈1;环己烯5.5;2-戊烯10.7;硝基苯17.1;苯甲醛34;丙烯醇39;丙酮79;苯乙烯252。活化能为
The new most active Nguyen copper catalyst preparation is to 60% A1-40% Cu alloy with sodium hydroxide solution at 0 ~ 10 ° C digestion continued digestion at 90 ° C 45 minutes. Its activity is about 70% of normal Nguyen nickel. Its decrease in hydrogenation catalytic activity is proportional to time. After 5 months, the activity decreased by only 1/3. The relative rates of hydrogenation at 127 ° C were butyronitrile 1; cyclohexene 5.5; 2-pentene 10.7; nitrobenzene 17.1; benzaldehyde 34; allyl alcohol 39; acetone 79; styrene 252. Activation energy is
