Abstract
This invention discloses a method for preparing tert-butyl benzoate peroxide using a microchannel reactor, comprising the following steps: adding liquid alkali to tert-butyl hydroperoxide, allowing it to stand and separate into layers, and obtaining the lower sodium salt; passing the obtained sodium salt into the microchannel reactor, simultaneously passing benzoyl chloride into the microchannel reactor for mixing and reaction; passing the material emanating from the microchannel reactor into an RTB reactor for incubation and reaction to obtain crude tert-butyl benzoate peroxide; purifying the crude tert-butyl benzoate peroxide to obtain tert-butyl benzoate peroxide. This invention employs continuous feeding and achieves the synthesis reaction through a microchannel reactor, reducing the reaction time from several hours to tens of seconds to several minutes, significantly improving reaction efficiency. The entire reaction process in the microchannel reactor used in this invention is a continuous reaction, which is safe and environmentally friendly, has high production efficiency, requires a small equipment footprint, is simple to operate, reduces manual operation, and lowers production costs.
