| titleOfInvention | A kind of high-quality high-boiling silicone oil and preparation method thereof |
| abstract | The invention discloses a high-quality high-boiling silicone oil and a preparation method thereof. The high-boiling organochlorosilane and trimethylchlorosilane are used as raw materials for co-hydrolysis, and the trimethylchlorosilane is used as an end-capping agent under acidic conditions to react The temperature is controlled at 10-50°C for hydrolysis, the dropwise flow rate is controlled at 480-530g/h, the balance is 0.5-2h after the dropwise addition, the acid water is left to stand for layering to remove the acid water, neutralized with a neutralizing agent for 0.5-3h, and the alkali is removed. Water, decolorized with activated carbon, filtered, de-lowed at normal pressure, and gradually heated to 180°C at ‑0.096 MPa to remove low boilers and alkanes to prepare high-quality high-boiling silicone oil. The method has mild reaction conditions and simple reaction process. |
