(上接第3期第34页)实施例2在实际工艺条件下,对腐蚀试验试样进行研究,以确定适用于该工艺的结构材料。在实施例1的共沸精馏塔内,将两组腐蚀试样依次放置在塔盘15上,然后取出并检查以确定每种材料的腐蚀速率。每组腐蚀测试试样的结果如下所 (Continued on page 34, page 34) Example 2 In the actual process conditions, corrosion test specimens were studied to determine the structure of materials suitable for the process. In the azeotropic distillation column of Example 1, two sets of corrosion samples were sequentially placed on a tray 15 and then taken out and examined to determine the corrosion rate of each material. The results of each set of corrosion test specimens are as follows
