摘要

研究表明，从次硝酸铋[Bi6O5(OH)3](NO3)5⋅3H2O 中获得高纯度（杂质金属和硝酸根离子含量低）的次水杨酸铋 BiC7H5O4 是可取的。用氢氧化钠溶液将其转化为氧化物 Bi2O3，然后在 60-85°C 温度下用乳酸-水杨酸溶液将氧化铋转化为亚水杨酸铋 BiC7H5O4。

Preparation of Bismuth Subsalicylate from Bismuth Subnitrate

It was shown that bismuth subsalicylate BiC₇H₅O₄ of high purity (with low contents of impurity metals and nitrate ions) is advisable to obtain from bismuth subnitrate [Bi₆O₅(OH)₃](NO₃)₅⋅3H₂O through converting it into oxide Bi₂O₃ by treating with a solution of sodium hydroxide and then into bismuth subsalicylate BiC₇H₅O₄ by treating bismuth oxide with a lactic acid–salicylic acid solution at a temperature of 60–85°C.
