Reactions of isopropyl and of undecyl radicals with meta- and para-substituted toluenes are reported. The results demonstrate that the reactivities of toluenes are due to both benzyl-H abstraction and addition of the alkyl radicals to the aromatic ring. Relative reactivities yield curved Hammett plots, consistent with kinetic data reported by Dutsch and Fischer. Abstractions and ring additions occur with comparable rates, but opposite Hammett slopes. Addition is favored by electron-withdrawing and abstraction by electron-donating substituents. The effects of substituents on the dissociation energies of benzyl C-H bonds are shown to be the major factor influencing reaction rates for benzyl-H abstraction by alkyl radicals.
ONLINE CONTINUOUS FLOW PROCESS FOR THE SYNTHESIS OF ORGANIC PEROXIDES USING HYDROGEN PEROXIDE AS RAW MATERIAL
-
Paragraph 0294, (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.
PROCESS FOR THE PRODUCTION OF DIACYL PEROXIDES
-
Page/Page column 15; 16, (2020/12/30)
Process for the production of a diacyl peroxide involving the reaction of an anhydride with an aldehyde and oxygen, removal of the formed carboxylic acid, production of an anhydride from said carboxylic acid, and recycling of the anhydride within the process.
