In August 2025, the China National Intellectual Property Administration (CNIPA) granted a patent application titled Synthesis Process of 3H-Heptamethyltrisiloxane, with publication number CN120484007A and filing date in July 2025.
According to the patent abstract, the invention falls within the technical field of siloxane synthesis, specifically relating to the preparation process of 3H-heptamethyltrisiloxane. The process steps are as follows: charge methyldichlorosilane, hexamethyldisiloxane and metal chloride into a reactor, conduct temperature-controlled reaction, and obtain the target product after separation. The invention adopts metal chloride as the catalyst. Via the activation-silicon addition reaction between methyldichlorosilane and hexamethyldisiloxane, controllable insertion of Si-H bonds and recyclable utilization of the catalyst are realized.
The invention eliminates safety hazards such as acid wastewater generation and hydrogen gas evolution existing in conventional processes, lifting production efficiency and operational safety. The Si-Cl bonds of methyldichlorosilane in raw materials undergo rearrangement to form trimethylchlorosilane. As an essential feedstock for manufacturing organosilicon products including hexamethyldisiloxane and MQ silicone resin, trimethylchlorosilane extends the service cycle of Si-Cl bonds in the silicone industry and cuts comprehensive production costs.
