Abstract
A method for preparing peroxide, including a step of treating, in a reaction medium, a component having at least one tertiary alcohol grouping with a compound having at least one tertiary hydroperoxide function in the presence of a catalyst, said method being characterized in that the catalyst includes a sulphonic acid and a inorganic acid, the molar ratio between the sulphonic acid and the aforementioned component including at least one tertiary alcohol grouping ranges from 0.05 to 0.8, and the molar ratio between the inorganic acid and the aforementioned component including at least one tertiary alcohol grouping ranges from 0.05 to 0.8. Also, to the peroxide resulting directly from said preparation method.
Claims15
A process for preparing peroxide, comprising a step of placing in contact in a reaction medium a component containing at least one tertiary alcohol group with a compound containing at least one tertiary hydroperoxide function in the presence of a catalyst, wherein:
- the catalyst comprises a sulfonic acid and a mineral acid,
- the mole ratio between the sulfonic acid and said component comprising at least one tertiary alcohol group is between 0.05 and 0.8, and
- the mole ratio between the mineral acid and said component comprising at least one tertiary alcohol group is between 0.05 and 0.8.
