Technological innovation in long-chain alkyl silicone oil contributes to industrial upgrading

1. New preparation method reduces costs:
Long-chain alkyl silicone oil, as a lubricating oil, mold release agent, etc., is widely used in fields such as textiles and cosmetics. At present, a method for preparing long-chain alkyl silicone oil through thiol double bond reaction has been developed. This method uses vinyl silicone oil and long-chain alkyl mercaptans as raw materials, without the need for platinum catalysis. It solves the problems of high cost of platinum catalysts and platinum residue in products, significantly reducing production costs.

2. Significant advantages in reaction characteristics:
The thiol double bond reaction is a click chemistry reaction, featuring fast reaction rate, high directional selectivity, mild reaction conditions and strong reaction adaptability. The preparation of long-chain alkyl silicone oil by this method can react rapidly under mild conditions, and the product has high purity and better quality.

3. Excellent product performance:
The long-chain alkyl silicone oil prepared by the new method is colorless and transparent, with good thermal stability. It can remain stable at 350℃ and has great potential in mold release agents and lubricating oils. At the same time, it also has good hydrophobicity and safety, and is suitable for fields such as cosmetics and fabric hydrophobic finishing.

4. Promote green development of industries
This new preparation method conforms to the concept of green chemistry, reduces the use of precious metal catalysts, lowers the risk of environmental pollution, provides strong support for the green and sustainable development of the long-chain alkyl silicone oil industry, and is expected to promote further upgrading of related industries.
