| Abstract: |
| The synthesis process of tert-butyl hydroperoxide（TBHP） was optimized. In the traditional
TBHP synthesis process，the amount of catalyst sulfuric acid was large，resulting in high content of sulfuric
acid in the reaction waste，so the treatment of “three wastes” was difficult. In the new synthesis process，
p-toluenesulfonic acid was used as the catalyst，and the optimum process conditions were determined as
follows：the molar ratio of p-toluenesulfonic acid/tert-butyl alcohol/hydrogen peroxide was 0. 2/1/1. 4，the
reaction temperature was 30～35 ℃，and the reaction time was 3 h. Under the optimized process conditions，
the TBHP yield was high and quality was excellent，and the amount of reaction waste liquid was small，which
simplified the treatment process of the “three wastes” |
