Production
Synthesis
- Timakova process[1]
- Oxidize metallic bismuth preliminarily with atmospheric oxygen
- Purify bismuth from accompanying metals with nitric acid by its precipitation from nitrate solutions in the form of trihydroxo-pentaoxo-hexabismuth (III) trihydrate
- Transform it into bismuth (III) oxide salicylate by treatment with the aqueous solution of salicylic acid.
- Other process sketches include
- Boil an aquaeous mixture of 9.4 g of bismuth oxide and 9.4 g of salicylic acid for 6 hours.
- Combine bismuth hydroxide with salicylic acid at 90°C.
