What are the synthesis methods and processes of di-tert-butyl peroxide?

Di-tert-butyl peroxide, also known as initiator A and vulcanizing agent dtbp, is a colorless to slightly yellow transparent liquid, insoluble in water, miscible with benzene, toluene, acetone, and other organic solvents, highly oxidized, Flammable, stable at room temperature, insensitive to impact, and one of the stable organic peroxides. At room temperature, its properties remain unchanged for a long time, and its vapor forms an explosive mixture with air.

In traditional kettle production, tert-butanol needs to obtain di-tert-butyl peroxide through a two-step method, that is, mono-tert-butyl peroxide is obtained and then used as a raw material for secondary peroxidation. The reaction mechanism is as follows:

Using tert-butyl alcohol as raw material, it reacts with hydrogen peroxide under the action of sulfuric acid to form tert-butyl hydroperoxide, which then reacts with tert-butyl alcohol. The existing problems are: for safety reasons, the concentration of hydrogen peroxide is low, the reaction time is long, and more waste sulfuric acid wastewater is produced, so the reaction process is difficult to control.
