Chemical synthesis method of organic peroxide

The invention discloses a chemical synthesis method of organic peroxide. The chemical synthesis method comprises the following step that a condensation reaction is carried out on metal+para 2-cumene alcohol (m+p DC for short) and tert-butyl hydroperoxide (TBHP for short), so that a meta+para bis-(tert-butyl peroxy isopropyl)benzene (m+p BIPB for short) is obtained. According to the process disclosed by the invention, waste sulfuric acid is converted into a chemical byproduct, so that the pollution pressure of the waste sulfuric acid can be solved, and economic benefits can be obtained. 70% sulfuric acid only with 1%-3% of the total amount of the reaction materials is added in the reaction, and the completion of the synthesis reaction is successfully completed under the action of a 7# accelerator, so that the consumption of the 70% sulfuric acid and 30% NaOH is greatly reduced.
