Abstract
Bismuth salts of phosphorylated and/or sulfonated saccharides can be prepared in one reaction vessel from a corresponding metal salt reactant, a water soluble organic acid, and a bismuth substance. For example, a complex salt of bismuth hydroxide sucrose octasulfate can be prepared in high yield and good purity from potassium sucrose octasulfate, trifluoracetic acid, and bismuth hydroxide.
