Properties and stability

1. Chemical properties: When heated with alkali, the ether bond is easily broken. When heated to 130°C with hydrogen iodide, it decomposes to generate methyl iodide and phenol. When heated with aluminum trichloride and aluminum tribromide, it decomposes into halomethane and phenoxide. Heated to 380~400℃, it decomposes into phenol and ethylene. Dissolve anisole in cold concentrated sulfuric acid, and add aromatic sulfinic acid. A substitution reaction occurs at the para position of the aromatic ring to generate sulfoxide, which appears blue. This reaction can be used to test aromatic sulfinic acids (Smiles test).

2. Rats were injected subcutaneously with LD50: 4000mg/kg. Repeated contact with human skin can cause degreasing and dehydration of cell tissues and irritate the skin. The production workshop should have good ventilation and the equipment should be sealed. Operators wear protective equipment.

3. Stability[20] Stable

4. Incompatible substances[21] Strong oxidants, strong acids

5. Polymerization hazard[22] No polymerization

Storage method

This product should be sealed and stored in a cool, ventilated place away from light.

Synthesis method

It is prepared by reacting the methylating agent dimethyl sulfate with phenol in an alkaline solution. Mix phenol and sodium hydroxide solution in 10Slowly add dimethyl sulfate. Add to heat and heat to40reflux reaction18h, then let it stand to separate the oil layer, dry it with anhydrous calcium chloride and then reduce and distill it to obtain anisole.


It is obtained by reacting methyl chloride into liquid ammonia of sodium phenolate.
It is obtained by heating phenol and methanol.
It is derived from the reaction of phenol and dimethyl sulfate in the presence of sodium hydroxide.

Purpose

Solvent. Organic synthesis intermediates.
