Introduction
M-fluorobenzaldehyde. The following is an introduction to the properties, uses, preparation methods and safety information of m-fluorobenzaldehyde:
Quality:
- Appearance: M-fluorobenzaldehyde is a colorless or yellowish liquid.
- Solubility: Soluble in organic solvents such as ethers, alcohols and ether alcohols.
Use:
- High-efficiency insecticides: M-fluorobenzaldehyde, as an intermediate in organic synthesis, is widely used in the agricultural field to prepare high-efficiency insecticides, such as insecticides CFOFLUOROETHYLENE or other insecticide raw materials.
- Chemical synthesis: M-fluorobenzaldehyde is often used as an intermediate in organic synthesis and can be used to prepare other compounds, such as m-fluorophenyl oxalate and camphor ethanol.
Method:
- There are two main preparation methods for m-fluorobenzaldehyde: fluoride method and fluorination method. Among them, the fluoride method is obtained by reacting m-fluorophenylmagnesium fluoride with formaldehyde; The fluorination method is obtained by hydrolysis of p-toluene and antimony trichloride in a chlorine atmosphere.
Safety Information:
- It is very important that m-fluorobenzaldehyde is a toxic substance and should be operated in well-ventilated conditions and appropriate personal protective equipment should be worn.
- During use or storage, avoid mixing with strong oxidants, alcohols and other substances to avoid dangerous reactions.
