Description
Organic compound, salt of alkaline metal sodium and organic trichloroacetic acid. Doesn't form water hydrates.
Reaction between hydrocarbonate, carbonate or sodium hydroxide and trichloroacetic acid
Chemical equation:
100.00g of sodium trichloroacetate а 45.32g of sodium hydrocarbonate or 28.59g of sodium carbonate or 21.58g of sodium hydroxide is required.Add acid to the flask, then add small parts of sodium compound with stirring until heating will stop (attention, the solution may boil!) or, if you use carbonate, until carbon dioxide emission will stop.
Notes
It's probable that there is an unknown hydrate which forms from water solution, because crystals erode in the open air within minutes. But there is no information about it in the literature.
For crystal storing use hermetic vessel with wadding moistened with such solution near the crystal. You can use such alternatives as vessel with vaseline or vegetable oil, organic non-hygroscopic solvent (kerosene or liquid paraffin). Also you can use acrylate polymer or another kinds of solidifying plastic.
