Recently, significant news emerged from the domestic organosilicon industry—a research team has achieved a breakthrough in the research of the "disproportionation of chlorosilanes to prepare dimethyldichlorosilane," laying a new technological foundation for improving the domestic production rate of high-end organosilicon monomers and reducing production costs.

Dimethyldichlorosilane (DMDCS) is a crucial raw material for the production of silicone rubber, silicone oil, and silicone resin, and its market demand continues to rise. However, traditional production routes suffer from high energy consumption, numerous byproducts, and stringent equipment requirements, consistently representing a technological bottleneck for efficiency improvement in the industry. This research team focused on the disproportionation reaction of chlorosilanes, achieving a significant improvement in the selectivity and yield of dimethyldichlorosilane by optimizing the catalyst system and controlling reaction pressure and temperature.

According to the project leader, the new process utilizes a composite catalyst with high activity and stability, resulting in more efficient redistribution of methyl groups among chlorosilane molecules, reducing byproducts by approximately 20%, and significantly lowering overall energy consumption. More importantly, this technology has already achieved stable operation in a pilot plant, meeting the conditions for industrial-scale expansion.

Industry experts believe that this technological advancement will not only help domestic companies further enhance their competitiveness in the high-end organosilicon materials field, but also provide a scalable process path for large-scale green manufacturing in the future. "The efficient utilization of the chlorosilane system is a crucial link in enhancing the value of the entire organosilicon industry chain, and this achievement is of great significance," said an industry analyst.

As research continues, the team plans to further explore continuous reaction modes and the comprehensive utilization of byproducts to achieve higher levels of low-carbon and energy-saving production. The industry generally expects this technology to be promoted to mainstream organosilicon manufacturers in the next few years, bringing a new round of technological innovation and cost optimization to the industry.
