Abstract
The application provides a method for preparing methyl silicone oil by using organic silicon high ring, which directly prepares the methyl silicone oil by using cheap organic silicon high ring, and reduces the production period and cost of the methyl silicone oil. In the application, semi-continuous feeding is adopted, the viscosity of the processed methyl silicone oil is controllable, the molecular weight distribution is narrow, the product conversion rate is greater than 85%, compared with the traditional process, the reaction process is stable, the utilization rate of the end-capping agent is high, and the amount is less.
