摘要
以高锰酸钾原料经氧化还原反应制备的二氧化锰为催化剂,催化3-氰基吡啶水解生成烟酰胺的反应。该类催化剂具有很高的催化活性和选择性,催化反应最高收率达到了99.57%,且几乎没有烟酸副产物。X-衍射图谱和IR图谱显示了该类催化剂的催化活性与它们的晶体结构及其表面的结合水有关。
The hydration of 3-cyanopyridine to nicotinamide in the presence of manganese dioxide catalyst has been investigated.Manganese dioxide catalyst prepared by redox method using KMnO4 had high activity and selectivity.In this study,the highest yield of this reaction reached 99.57%,almost without by-product nicotinic acid.The IR and X-ray diffraction indicated that the activity of this kind of catalysts was closely related with their crystal structures and the hydrated water of the MnO2 surface.
