Abstract: Disodium bicyclo[2.2.1]-heptane-2,3-dicarboxylate is synthesized from norbornene dicarboxylic andydride by neutralization hydrolysis and catalytic hydrogenation. By studying the effects of catalyst type, the amount of catalyst, reaction temperature and hydrogen pressure on the yield and purity of disodium bicyclo[2.2.1]-heptane-2,3-dicarboxylate, the suitable reaction conditions are obtained. The results show that the expensive catalyst of Pd/C can be replaced by inexpensive Renay Ni . The suitable reaction temperature is 60℃ and the suitable reaction pressure is 5MPa. The results of infrared spectrum analysis and nuclear magnetic resonance analysis are identical with the structural features of disodium bicyclo[2.2.1]-heptane-2,3-dicarboxylate.

摘要: 以降冰片烯二酸酐为起始原料, 经水解中和和催化加氢制备了双环[2.2.1]-庚烷-2,3-二羧酸钠。通过研究催化加氢步骤中催化剂种类、催化剂用量、反应温度和反应压力等关键因素对双环[2.2.1]-庚烷-2,3-二羧酸钠的收率和纯度的影响, 获得了适宜的反应条件。实验结果表明:催化剂雷尼镍可代替文献报道的价格昂贵的钯/炭催化剂完成催化加氢反应, 在反应温度为60℃、反应压力为5MPa的条件下进行催化加氢, 双环[2.2.1]-庚烷-2,3-二羧酸钠的收率大于95%;红外光谱及核磁共振分析表明, 所得加氢产物与双环[2.2.1]-庚烷-2,3-二羧酸钠结构特征吻合。
