A continuous flow production process for preparing organic peroxides directly from alcohols or alkanes takes very safe alcohols or alkanes as starting materials, and directly reacts to obtain designated peroxides. The production process is carried out in an integrated continuous flow reactor, and a safe starting source of alcohol or alkane is continuously added at the feed inlet of the integrated continuous flow reactor, and continuously provided with a designated peroxide at the discharge port of the integrated continuous flow reactor.
