Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a dimethyl silicone oil reaction kettle. Background Art

[0002] Silicone oil is a polysiloxane with chain structure of different polymerization degree. It is prepared by hydrolyzing dimethyldichlorosilane with water to obtain the primary polycondensation ring body, and then the ring body is cracked and distilled to obtain the low ring body. Then, the ring body, capping agent and catalyst are put together to obtain a mixture of various polymerization degrees. Silicone oil can be obtained by removing low boiling points through vacuum distillation.

Although stirring can be achieved in this way, the mixing effect is not good during the stirring process, thereby affecting the reaction efficiency. Therefore, it is necessary to design a dimethyl silicone oil reactor. Utility Model Content
