4,4,4-Trifluoro-1-phenylbutane-1,3-dione

1. product basic information table

nature of 2.

Benzoyltrifluoroacetone (BTA) is an important β-diketone fluorine-containing organic compound, which can be regarded as a derivative of acetylacetone. The hydrogen atom on the methyl group is replaced by a strongly electron-withdrawing trifluoromethyl group (CFL3). This compound exists in an enol-keto tautomeric equilibrium in solution and exists predominantly in the enol form. Due to the strong electron withdrawing effect of trifluoromethyl, the acidity (pKa ≈ 6.35,25°C) of BTA is significantly stronger than that of ordinary β-diketones, which makes it exhibit excellent chelating ability in metal ion coordination and extraction. The introduction of aromatic ring increases the molecular conjugation system, reduces the energy level, and expands its application potential in the field of photophysics.

This product has a melting point of 38-40°C, a boiling point of 224°C, and a low melting point solid state at room temperature. Soluble in ethanol, ether, chloroform and other organic solvents, 95% ethanol solubility ≥ 25 mg/mL; slightly soluble in water (0.24g/L,25°C). It has good thermal and chemical stability, but may react in the presence of strong oxidants.

3. uses

metal ion extraction and separation: As an efficient chelating extractant, it is widely used in solvent extraction, separation and purification of hafnium, zirconium and other rare metals, lanthanides and actinides.

Lithium resource extraction: In the ionic liquid (ILs) system, BTA can efficiently extract lithium ions from alkaline solutions (such as salt lake brine) without adding synergistic extractants (such as TOPO), with high selectivity and high reverse extraction rate, is an important direction of green lithium extraction technology.

Organic synthesis intermediates: an important building block for the synthesis of fluorine-containing medicines, pesticides and fine chemicals, especially in the preparation of fluorine-containing pyridine ketones herbicides and fluorine-containing quinoline compounds.

Luminescence and optical materials: As ligands of rare earth complexes (such as europium and terbium complexes), it is used to prepare high-performance fluorescent probes, OLED light-emitting layer materials and optical sensors.

Analytical chemical reagent: used as an analytical reagent for the spectrometric determination of heavy metal ions.

4. safety information

GHS Classification: Non-hazardous substances or mixtures (some sources are labeled as irritants). The dangerous goods symbol is Xi (irritant) and the hazard category code is R36/37/38, indicating that the product is irritant to the eyes, respiratory system and skin. Safety instructions are S24/25, I .e. avoid contact with skin and eyes.

Fire-fighting measures: water mist, alcohol-resistant foam, dry powder or carbon dioxide can be used to extinguish the fire. Hazardous gases such as carbon oxides and hydrogen fluoride may be produced during combustion, and firefighters should wear self-contained breathing apparatus.

Incompatible substances: strong oxidants.

Operation attention: suitable exhaust equipment should be provided in the place where dust is generated; avoid dust generation and inhalation of steam; operators should be specially trained and strictly abide by the operation procedures.

Storage conditions: sealed in a cool, dry, ventilated place, away from strong oxidants and fire sources.

Personal protection: wear protective glasses and protective gloves; if dust protection is required, it is recommended to use N95 (US) or P1 (EN 143) dust mask.

First aid measures:

inhalation: move the patient to fresh air and perform artificial respiration if necessary;

skin contact: rinse with soap and plenty of water;

eye contact: Flush with water for at least 15 minutes;
