Introduction
Methylphenylacetic acid. The following is an introduction to the properties, uses, preparation methods and safety information of p-totophenylacetic acid:
Quality:
- Appearance: The common appearance of methylphenylacetic acid is a white crystalline solid.
- Solubility: It is less soluble in water but can be soluble in most organic solvents.
Use:
Method:
- A common preparation method is obtained by transesterification of toluene and sodium carbonate. P-toluene reacts with alcohol, such as ethanol or methanol, to form p-toluene, which is then reacted with sodium carbonate to give methylphenylacetic acid.
Safety Information:
- Methylphenylacetic acid is stable at room temperature and may decompose under high temperatures, fire sources or light, producing toxic substances.
- Appropriate precautions should be taken when handling methamphenylacetic acid, such as wearing protective eyewear, gloves and protective clothing. Avoid inhalation, ingestion, or skin contact to avoid discomfort or injury.
- Methylphenylacetic acid should be stored away from ignition, strong oxidizing agents, and reactive metals in a dry, well-ventilated place.
