Triglycollamic Acid Bismuth sodium triglycollamate

Bismuth Oxide Triglycollamic Acid Sodium Carbonate... 

A mixture of 2.33 g of bismuth oxide (BijOa), 3.71 g of anhydrous sodium carbonate, and 7.64 g of triglycollamic acid and 40 cc of water was heated at B0°C on the water bath until all was dissolved. The solution was avaporated on the water bath to a syrup. The syrup was allowed to cool, during which time partial solidification occurred. It was then triturated with 300 cc of alcohol, and the solid anhydrous salt was collected on a filter, washed with alcohol, ground fine, and dried in a vacuum desiccator. This substance has a water solubility at 25°C of 31 S% by weight. It decomposes on heating in the melting point bath.
