| Thenoyltrifluoroacetone Basic information | |
| Product Name: | Thenoyltrifluoroacetone |
| CAS: | 326-91-0 |
| MF: | C8H5F3O2S |
| MW: | 222.18 |
| EINECS: | 206-316-7 |
| Mol File: | 326-91-0.mol |
| Thenoyltrifluoroaceton Chemical Properties | |
| Melting point | 40-44 °C(lit.) |
| Boiling point | 96-98 °C8 mm Hg(lit.) |
| density | 1.4373 (estimate) |
| Fp | 233 °F |
| storage temp. | 2-8°C |
| solubility | sparingly soluble in water, readily soluble in organic solvents. Distribution ratio between acidic water and benzene is about 40. In alkaline aqueous medium it exists in the enolate form, this being relatively more soluble in water. The equilibrium distribution ratio between benzene and alkaline aqueous medium (about pH 8) is about 1. In alkaline aqueous medium of pH > 9 TTA decomposes to trifluoroacetone and acetylthiophen. |
