Description

Technical Field

[0001] The utility model relates to the technical field of silicone oil reaction kettles, in particular to a constant temperature tank for organic silicone oil reaction. Background Art

[0002] Silicone oil is generally a colorless, odorless, non-toxic, non-volatile liquid. It has a very small vapor pressure, a high flash point and ignition point, and a low freezing point. With the difference in the number of chain segments n, the molecular weight increases and the viscosity also increases, so silicone oil can have various viscosities. If you want to make low-viscosity silicone oil, you can use acidic clay as a catalyst and perform polymerization at a temperature of 180°C, or use sulfuric acid as a catalyst and perform polymerization at a low temperature. Alkaline catalysts can be used to produce high-viscosity silicone oil or viscous materials.

[0003] In the process of preparing silicone oil compounds, the reaction process of silicone oil needs to be maintained within a suitable temperature range. For example, when preparing low-viscosity silicone oil in a reactor, the reactor needs to be maintained at a higher temperature threshold, while when producing high-viscosity silicone oil, the reactor needs to be maintained in a lower temperature range. However, the external environment often affects the temperature balance inside the reactor, so those skilled in the art hereby propose a thermostatic tank for organic silicone oil reaction.
