What kind of acid is used to adjust the PH value of high-hydrogen silicone oil?

Silicon oil with high hydrogen content can be adjusted with sulfuric acid.
Silicone oil with high hydrogen content is not afraid of alkali and transition metal ions, and is not afraid of acid. For example, when synthesizing low hydrogen silicone oil from high hydrogen silicone oil and D4 and MM, the catalyst used is concentrated sulfuric acid. In the presence of concentrated sulfuric acid, the hydrogen silicone oil is stable. However, once the hydrogen-containing silicone oil is added with alkaline water, it will decompose immediately and produce a large amount of hydrogen. Therefore, the pH can be adjusted slowly with concentrated sulfuric acid, and finally the salt can be removed by filtration, and the water can be evaporated to obtain pure high-hydrogen silicone oil.
