Introduction
Quality:
- Methylbenzene is a colorless liquid with a peculiar aromatic odor.
- Trimethylbenzene is insoluble in water and soluble in organic solvents such as alcohols, ethers and ketone solvents.
Use:
- M-trimethylbenzene is mainly used as a solvent in organic synthesis.
- Used in the preparation of flavors, pigments, dyes and fluorescents.
- For the preparation of inks, cleaners and coatings.
Method:
- Methylbenzene can be prepared from toluene by alkylation. A common method is to react toluene with methane under the conditions of a catalyst and appropriate temperature to form homoxylene.
Safety Information:
- Trimethylbenzene has certain toxicity and irritating effects on the skin and eyes.
- Trimethylbenzene is flammable and should be kept away from open flames and high temperatures. Pay attention to fire prevention measures when storing and using.
- When using x-trimethylbenzene, provide good ventilation conditions and avoid inhalation of its vapors.
