- ONLINE CONTINUOUS FLOW PROCESS FOR THE SYNTHESIS OF ORGANIC PEROXIDES USING HYDROGEN PEROXIDE AS RAW MATERIAL
-
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 ORGANIC PEROXIDES ON SITE
-
The present invention relates to a process for preparing an organic peroxide and the subsequent use thereof in a (co)polymerization reaction, wherein the process comprises the steps (a), b1 (or b2), (c), (d), and (e), said steps being: (a) the reaction of chlorine with carbon monoxide, (b1) the reaction of phosgene formed in step (a) with one or more alcohols in order to prepare chloroformate, (b2) the reaction of phosgene formed in step (a) with one or more organic acids to prepare acid chloride, optionally in the presence of a catalyst suitable to effect the reaction of phosgene with said one or more organic acids, (c) the reaction of chloroformate, acid chloride, or mixture thereof with (in)organic hydroperoxide and base in an aqueous environment, (d) the transfer of organic peroxide formed in step (c) to a polymerization vessel, and (e) the (co)polymerization of monomer in the polymerization vessel in the presence of one or more organic peroxides transferred in step (d), wherein all of steps (a)-(e) are conducted at one site.
