Introduction
O-trifluoromethylbenzoic acid is an organic compound. The following is an introduction to its properties, uses, manufacturing methods and safety information:
Quality:
- Appearance: O-trifluoromethylbenzoic acid is a white crystal or crystalline powder.
- Solubility: It is soluble in organic solvents such as ethanol and ethers, but insoluble in water.
- Stability: It is stable at room temperature, but can be dangerous when exposed to heat or strong oxidizing agents.
Use:
- O-trifluoromethylbenzoic acid is often used as an important intermediate in organic synthesis.
- It can also be used as a photosensitizer, photopolymerizer, and initiator for polymerization reactions.
Method:
- The preparation of o-trifluoromethylbenzoic acid usually starts from o-cresol. Ph-benzophenol is reacted with trifluorocarboxylic anhydride to form o-trifluoromethylbenzoyl fluoride. Then, the resulting o-trifluoromethylbenzoyl fluoride is reacted with the lye to form o-trifluoromethylbenzoic acid.
Safety Information:
- O-trifluoromethylbenzoic acid should be stored in a dry, cool, well-ventilated place.
- Wear appropriate protective gear, including eyeglasses, gloves, and a face shield.
- Avoid inhalation, ingestion, or skin contact, and wash immediately in case of accidental contact.
- It can be harmful to the environment, care needs to be taken to properly handle and dispose of waste.
