Nature:
3,4,5-Trifluorotoluene is a colorless liquid with a special aromatic smell at room temperature. It is a combustible substance that reacts violently with oxygen. It has a density of 1.408g/cm³, a boiling point of 111°C and a melting point of -45°C. It is a volatile solvent, insoluble in water, soluble in organic solvents.
Use:
3,4,5-Trifluorotoluene has a high electron density and is widely used as an intermediate in organic synthesis. It can be used to prepare chemicals such as pesticides, pharmaceuticals, dyes and coatings. In addition, it can also be used as a solvent, surfactant and additive in high temperature coatings.
Method:
The preparation method of 3,4,5-Trifluorotoluene is usually obtained by fluorination reaction of toluene. The common method is to use hydrofluoric acid hydrogen fluoride (HF-F) in the presence of hydrofluoric acid (HF), or use a fluorine-containing reagent such as cesium trifluoride (CsF3) or hydrogen fluoride silver difluoride (AgF2) A fluorination reaction is carried out.
Safety Information:
3,4,5-Trifluorotoluene is irritating. Contact with skin and eyes may cause irritation and burns. Inhalation of high concentrations of vapors may cause coughing, shortness of breath, headache and dizziness. It is a combustible substance and should avoid contact with high temperature, open flame and oxygen. During use and storage, appropriate safety measures must be taken, including wearing protective gloves, glasses and protective clothing to ensure good ventilation. In case of misuse or contact, seek medical attention immediately.
