摘要
4 (4 甲氧基苯基 ) 3 丁烯 2 酮的乙醇溶液在不同的pH值条件下用瑞尼镍催化氢化 ,产物用气相色谱分析 ,研究瑞尼镍的催化选择性与反应介质pH值的关系。实验结果表明 ,在碱性和酸性条件下 ,瑞尼镍的氢化选择性降低 ,在中性条件下 ,瑞尼镍的选择性大于 99%
Methoxyphenyl) 3 buten 2 one is hydrogenated by Raney′s Ni in ethyl alcohol at different pH.The product is analized by GC.The relationship between the catalytic selectivity of Raney′s Ni and the pH of the reaction medium is studied.The results show that the catalytic selectivity of Raney′s Ni at acidic or basic condition is decreased.The catalytic selectivity of Raney′s Ni is more than 99% at pH 7.
