Continuous process breakthroughs overcome bottlenecks, ushering high-hydrogen silicone oil production into the era of low carbon
High-hydrogen silicone oil, due to its high hydrogen content and strong reactivity, enjoys strong demand in the synthesis of high-end materials. However, the traditional production process has long faced issues such as high energy consumption, low yield, and significant environmental pressure. Recently, the mature application of continuous production technology has injected new impetus into the high-hydrogen silicone oil industry, achieving a dual improvement in product quality and green production.

1. Process Innovation: Solving the pain points of traditional production
The traditional solvent-based production of high-hydrogen silicone oil requires the use of concentrated sulfuric acid for polymerization and multiple alkali neutralization and water washing processes. This not only consumes a large amount of water resources but also generates wastewater and by-products, resulting in a product yield of less than 70% and significant fluctuations in hydrogen content. The new continuous production technology uses chlorosilane and methyl hydrogen dichlorosilane as raw materials and achieves efficient conversion of raw materials through a water hydrolysis circulation reaction system. The reaction temperature is controlled at 5°C to 30°C, eliminating the need for high-temperature and high-pressure environments, thereby reducing energy consumption from the source.

2. Circulation Technology: Achieving efficient resource utilization
The core advantage of this process lies in its all-process circulation design. The dilute acid generated from the hydrolysis reaction is not directly discharged but is separated and returned to the hydrolysis system for reuse, significantly reducing acid consumption and wastewater generation; the low-molecular substances separated during the polymerization reaction are also recycled to the initial reaction stage, increasing resource utilization by more than 30% compared to traditional processes. At the same time, a fixed-bed reaction system combined with environmentally friendly catalysts such as acid white earth replaces traditional strong acid catalysts, avoiding the risk of heavy metal residue.

3. Quality Upgrade: Precisely controllable hydrogen content
By optimizing the raw material ratio and reaction parameters, the continuous production process can stably produce high-hydrogen silicone oil with a hydrogen content of 1.56 to 1.60 wt%, with the hydrogen content fluctuation range reduced to ±0.02%, far exceeding the industry average. The refined product has extremely low impurity content and can meet the strict requirements for raw material purity in fields such as semiconductor packaging and high-end silicone rubber synthesis, breaking the bottleneck of high-quality product production.

4. Industrialization Prospects: Low-carbon attribute as core competitiveness
Currently, this process has the conditions for large-scale promotion. Compared to traditional processes, the unit energy consumption is reduced by 40%, production costs decrease by 25%, and the total amount of pollutant emissions is significantly reduced, aligning with the global trend of low-carbon manufacturing. With the tightening of environmental protection policies, continuous production technology with recycling characteristics is expected to become the industry mainstream, promoting the transformation of high-hydrogen silicone oil production capacity towards green and efficient.
