Catalyst of Organic Synthesis of Tetramethylammonium Chloride:
Tetramethylammonium chloride is the phase transfer catalyst in organic synthesis phase with its catalytic activity being stronger than triphenylphosphine and triethylamine.
At room temperature, Tetramethylammonium chloride is a white crystalline powder, and is volatile, irritant, and easy to absorb moisture.
Tetramethylammonium chloride is easily soluble in methanol, soluble in water and hot ethanol but insoluble in ether and chloroform.
Being heated to above 230 °C causes Tetramethylammonium chloride’s decomposition into trimethylamine and methyl chloride.
Electrolytic preparation of tetramethylammonium hydroxide:
Tetramethylammonium hydroxide is a kind of organic base, and has a broad range of application in the field of both industry and scientific research.
In our own country, Tetramethylammonium chloride is mainly used as the catalyst in the synthesis of organic silicon products, such as synthetic silicone oil, silicone rubber, and silicone resin.
Although Tetramethylammonium chloride has a low usage amount, but it can significantly affect both the yield and quality of Tetramethylammonium chloride.
In abroad, Tetramethylammonium chloride is mainly used for polyester-based polymers, textiles, plastics, food, leather, wood processing, electroplating, and some kinds of microorganisms.
Now tetramethylammonium hydroxide has entered the advanced technology areas.
For example, in the field of manufacturing industry of electronic circuit and microscopic sheets production, Tetramethylammonium chloride can be used as the cleaning agent of integrated circuit board as well as the anisotropic corrosive agents of the Si-SiO2 interface in semiconductor microfabrication technique.
With the development of science and technology, the requirements of this type of chemicals are also increasing, posing higher requirements for both the quality and the quantity of the tetramethylammonium hydroxide.
The basic principle of using electrolytic method for preparation of tetramethylammonium hydroxide is that the aqueous solution of tetramethylammonium chloride in the anode compartment of the electrolytic bath, under the action of the electric force, has its chloride ions migrate to the direction of anode until discharge of anode occurs to generate chlorine.
Meanwhile, because of the selective permeability of the ion-exchange membrane, chloride can’t penetrate through the ion-exchange membrane through diffusion.
Instead, only tetramethylammonium ions can selectively penetrate into the cathode compartment through, and be enriched over there.
The water molecule in the electrolyzer cathode chamber is decomposed into hydrogen and hydroxyl ions.
The latter one exactly binds to the tetramethylammonium ions migrated from the anode chamber to generate tetramethylammonium hydroxide.
With the increase of electricity, tetramethylammonium hydroxide concentration continues to improve, finally achieving the desired final concentration of crude.
The anodic electrochemical reaction is:
(CH3) 4NCl → (CH3) 4N ++ Clˉ2Clˉ-2e → Cl2 ↑
The cathodic electrochemical reaction is:
H2O → H + + OHˉ (CH3) 4N ++ OHˉ → (CH3) 4NOH 2H ++ 2e → H2 ↑
The total reaction is:
2 (CH3) 4NCl + 2H2O → 2 (CH3) 4NOH + H2 ↑ + Cl2 ↑
The hydrogen generated during electrolysis is vented with the resulting chlorine absorbed by alkaline solution to generate sodium hypochlorite which is major raw materials for producing bleach.
Therefore, this method of producing tetramethylammonium hydroxide is simple with high purity and causing no environmental pollution.
