39635-79-5 - Preparation method
Open Data Verified Data
Add bisphenol S, hydrogen peroxide, water, and chlorobenzene to the reaction kettle, cool with salt water to 10 ℃, and then add bromine dropwise, n (bisphenol S): n (bromine): nn (hydrogen peroxide)=110:214:216. Control the droplet acceleration to ensure that the solution temperature does not exceed 30 ℃. After adding bromine, stir at a constant temperature for 3 hours, raise the temperature to 80 ℃, maintain the temperature for 1 hour, add an appropriate amount of sodium sulfite aqueous solution, neutralize the excess bromine, adjust the pH of the solution to 6, filter, and dry at 80 ℃. Tetrabromobisphenol S.
