The main differences between ferrocene and N-methylaniline

Physical Properties:

Ferrocene (dicyclopentadienyliron) can be used: As a scaffold for chiral ligands in asymmetric catalysis.

7.Chemical Parameters:

The main differences between ferrocene and N-methylaniline

1. Application Fields

Ferrocene

Fuel additive: used as a combustion rate catalyst for gasoline or rocket propellants, improving combustion efficiency and replacing toxic tetraethyl lead-5.

In the field of medicine, derivatives are used to treat anemia, tumors, and applied in photodynamic therapy.

Environmental Protection and Materials: Catalytic treatment of pollutants to improve the performance of polymer materials.

N-methylaniline

Pesticide synthesis: used for the production of insecticides and herbicides such as thiamethoxam and methyl herbicide.

Dyes and Chemicals: Used as dye intermediates (such as cationic brilliant red FG) and rubber additives.

Fuel improvement: increase gasoline octane rating, but with limited usage and control of residual 16.

2. Synthesis method

Ferrocene

Chemical synthesis method: Sodium cyclopentadienyl reacts with ferrous chloride to form ferrocene 3; Alternatively, electrolysis can be used to reduce cations through an iron plate electrode and combine them with cyclopentadiene.

Raw materials and conditions: Cyclopentadiene, iron powder or ferrous chloride are required, and the reaction often requires nitrogen protection and high temperature (such as 300 ℃).

N-methylaniline

Aniline methylation: Aniline reacts with methanol over copper zinc chromium catalyst or sulfuric acid catalyst to produce crude product, which is then distilled and purified.

Laboratory synthesis: Using dimethyl sulfate as a methylating agent, product 6 was separated through stepwise acid-base treatment.

3. Raw materials

Ferrocene:

The core raw materials are cyclopentadiene (C ₅ H ₆) and iron sources (such as iron powder and ferrous chloride) 37.

The auxiliary materials include solvents such as tetrahydrofuran and diethylamine.

N-Methylaniline:

The basic raw materials are aniline (C ₆ H ₅ NH ₂) and methylation reagents (such as methanol, dimethyl sulfate).

Catalysts commonly used include copper, zinc, chromium, or phosphorus trichloride.

4. Packaging method

Ferrocene:

Sealed moisture-proof packaging (such as aluminum foil bags or galvanized drums) is usually used to avoid contact with oxidants, and it should be labeled as "flammable solid" 57.

N-Methylaniline:

Commonly used dark glass bottles or plastic drums for packaging, should be stored away from light and labeled as "toxic" to prevent volatilization and oxidation
