Patent application for a process for production of effective catalysts for polymerization of unsaturated compounds (in German)
Organic compounds which contain one or more double carbon bonds per molecule frequently display the ability of polymerizing with each other and with other compounds. It is mainly compounds containing peroxide that serve as catalysts for such operations. Examples of recommended substances are hydrogen peroxide, ozone, perbenzoic acid, benzoin peroxide, peroxide-containing ethers, persulfates, etc. It was found that a catalyst of much greater effectiveness in the polymerization of unsaturated compounds can be obtained from one of the previously-known catalysts if the hydrocarbons are processed with lateral-chain substances (e.g., toluene, xylene, ethyl benzene, propyl benzene, diethyl benzene, etc.) in boiling heat with damp air. In this process there develops a small measure of peroxide of previously unknown make-up, which possess outstanding catalytic effectiveness. For production of the catalyst, the aromatics are heated by return-flow cooler and conducted for several hours through an air stream which has been saturated with steam. Oxidation can be undertaken with other substances also; for example, oxygen, ozone, or compounds which give off oxygen. Activation with air, however, is the simplest way and yields the most effective catalyst. Examples of the process are provided.
