摘要：

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.
