ONLINE CONTINUOUS FLOW PROCESS FOR THE SYNTHESIS OF ORGANIC PEROXIDES USING HYDROGEN PEROXIDE AS RAW MATERIAL
-
Paragraph 0293, (2020/06/29)
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.
Method for preparing ketone peroxide by ferrite compound as catalyst
-
Paragraph 0030, (2019/01/21)
The invention discloses a method for preparing ketone peroxide by a ferrite compound as a catalyst. The method comprises that ketone and hydrogen peroxide undergo a reaction in the presence of a ferric oxide as a catalyst and the hydrogen peroxide is finally added when the temperature is raised to the reaction temperature. The ferric oxide replaces a titanium-silicon molecular sieve catalyst so that the cost of the catalyst is significantly reduced and the catalyst is easy to recover. The reaction conditions are low, the reaction conversion rate and selectivity are high under mild reaction conditions, the application range is wide, and the method can be used for production of a variety of ketones and its ketone peroxides and has very good application prospects.
Method used for preparing methylethyl ketone peroxide by taking acidic ion exchange resin as catalyst
-
Paragraph 0016, (2016/12/16)
The invention provides a method used for preparing methylethyl ketone peroxide by taking an acidic ion exchange resin as a catalyst. According to the method, butanone and hydrogen peroxide are taken as raw materials, the acidic ion exchange resin is taken as the catalyst, dibutyl phthalate is taken as a diluent, after constant temperature stirring reaction, an obtained mixture is allowed to stand for separation, and an obtained oil phase is methylethyl ketone peroxide. According to the method, the heterogeneous catalyst is adopted, so that the catalyst and the reaction materials can be separated easily, and the catalyst can be recycled for a plurality of times; reaction is stable, the temperature is increased slowly, and reaction is continuous and stable; product active oxygen content is 13%, and economic value is high; application of strong such as sulfuric acid is avoided, so that corrosion on equipment is less, environment pollution is not caused, and environmental benefit is relatively high.
