Solution Overview
Problem
Existing continuous processes for synthesizing organic peroxides face challenges such as long reaction times, scaling-up uncertainties, and inefficient workup processes, leading to unstable product quality and safety risks, as well as high production costs and inefficiencies.
Innovation Solution
An integrated continuous flow production process using hydrogen peroxide, a catalyst, and an oxidation substrate, which integrates oxidation and workup steps within a plug-and-produce reactor, enabling the direct production of organic peroxides like alkyl peroxides, dialkyl peroxides, peroxycarboxylic acids, diacyl peroxides, and peroxydicarbonates, with a production time of less than 6 minutes and simultaneous connection to downstream processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional batch processes are used for organic peroxide synthesis, then flexibility in production is maintained, but production time is long and productivity is low
Solution Approach 1:
The patent combines multiple process steps (oxidation reaction, workup, and purification) into a single integrated continuous flow reactor system. The reactor integrates the oxidation zone where hydrogen peroxide reacts with the substrate, followed by in-situ workup and purification zones, eliminating the need for separate batch processing steps and significantly reducing production time from hours to minutes.
Solution Approach 2:
The patent implements continuous flow processing where reactants are continuously fed into the reactor, the reaction proceeds continuously, and products are continuously extracted and purified. This continuous operation eliminates idle times between batches and maintains constant production flow, achieving production times of less than 6 minutes per batch equivalent output.
2Quantity of substance
If scale-up is performed in traditional processes, then production volume increases, but scaling-up uncertainties arise leading to unstable product quality
Solution Approach 1:
The patent uses continuous flow technology where reaction parameters (temperature, pressure, flow rates, residence time) are precisely controlled and can be independently optimized. By changing flow rates and residence times rather than simply increasing reactor size, the system can scale production volume while maintaining identical reaction conditions and product quality, eliminating traditional scaling-up uncertainties.
3Adaptability or versatility
If organic peroxides are stored and transported, then production flexibility is improved, but safety risks and production costs increase
Solution Approach 1:
The patent extracts the hazardous intermediate organic peroxide from the process by implementing just-in-time continuous production where the peroxide is generated and immediately used in downstream applications without isolation, storage, or transportation. The system produces the peroxide on-demand and feeds it directly to the next process step, eliminating safety risks associated with storing and transporting these sensitive compounds while maintaining production flexibility.
4Productivity
If workup process is separated from oxidation, then process control is simplified, but production time increases and productivity decreases
Solution Approach 1:
The patent merges the oxidation reaction zone with the workup and purification zones within a single continuous flow reactor system. The reactor is designed with distinct but integrated zones: the oxidation zone where hydrogen peroxide reacts with the substrate, followed by the workup zone where products are extracted, and the purification zone. This integration eliminates transfer times between separate units and enables continuous processing, achieving production times of less than 6 minutes.

AI summary
An online continuous flow production process for directly preparing organic peroxides by using hydrogen peroxide as a raw material. This production process uses hydrogen peroxide, catalyst, and an oxidation substrate as a raw material. Substrate will be turned to designated peroxides sequentially through oxidation and workup. This process is performed in a plug-and-produce integrated continuous flow reactor, and the raw materials are continuously fed to the reactor. So, specified peroxide can be continuously obtained at the outlet of the plug-and-produce integrated continuous flow reactor.
