- Acetone – Anhydrous 99.8% Purity. Our 99.8% acetone is anhydrous with a wide range of uses. Acetone is a colourless, volatile, flammable liquid and is the simplest and smallest ketone. It is miscible with water and serves as an incredibly important solvent in it’s own right and typically used for cleaning laboratories. Acetone is a common building block in organic chemistry.
- Jul 27, 2009 · 250ml of anhydrous acetone was then siphoned off from the top of the jar containing the MgSO4 and acetone, filtered through a coffee filter and was transferred to a smaller mason jar. Approximately 1545mg of fumaric acid can dissolve in 250ml of acetone, so approx. 1.7 grams were added to ensure complete saturation.

This is important because one milliliter of water, just one, will dissolve around two grams of cocaine. If you don't have anhydrous acetone, you'll literally pour your coke down the drain.
anhydrous acetone, starting from a suspension of lyophilized -glucosidase (BG) powders. During the entire process, the lyophilized BG is never in contact with water because the reaction system is kept under dry nitrogen ﬂux. It is demonstrated that solvents that do not dissolve proteins, such as acetone, cause no appreciable denaturation .

2 displacements. In acetone solution, other alkyl halides can be converted to alkyl iodides. a Although we might expect such a reaction to be reversible, using anhydrous acetone as the solvent can drive it forward. Sodium iodide is soluble in this solvent, whereas sodium chloride and sodium bromide are not.
