Organic silicon silicon powder processing monomer synthesis English

process flow

Introduction

Organic silicon silicon powder is widely ud in electronic, chemical and

other industries due to its excellent properties. The synthesis of organic

silicon silicon powder monomers is a key step in the production of organic

silicon silicon powder. In this article, we will introduce the English process

flow of the synthesis of organic silicon silicon powder monomers.

Process flow

The synthesis of organic silicon silicon powder monomers mainly includes

the following steps:

Step 1: Preparation of raw materials

The raw materials required for the synthesis of organic silicon silicon

powder monomers are dimethyldichlorosilane, methyltrichlorosilane, and

tetramethyldisiloxane. The three materials should be of high purity.

Step 2: Hydrolysis reaction

In a reaction vesl, add dimethyldichlorosilane and methyltrichlorosilane to

anhydrous toluene. Then, slowly add water while stirring the mixture. The

temperature of the reaction should be kept at about 10°C. Stir the mixture for

2 hours and then parate the organic and aqueous layers. The organic layer

is washed with distilled water until the pH value is neutral.

Step 3: Condensation reaction

In a reaction vesl, add the organic layer obtained in step 2 and

tetramethyldisiloxane. The mixture is heated to reflux for 5 hours under the

protection of nitrogen gas. After the reaction is complete, the mixture is

cooled and filtered. The obtained product is then purified by vacuum

distillation.

Step 4: Characterization

The synthesized organic silicon silicon powder monomer is characterized by

Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis

(TGA), and differential scanning calorimetry (DSC). The FTIR spectrum is

ud to identify functional groups, the TGA curve is ud to determine the

thermal stability, and the DSC analysis is ud to determine the melting

point of the product.

Conclusion

In summary, the synthesis of organic silicon silicon powder monomers is a

complex process that requires careful handling of raw materials and preci

temperature control. The English process flow prented in this article

provides a detailed guide on how to synthesize high-quality organic silicon

silicon powder monomers.
