  • Process for the preparation of N,N'-tetrathiodimorpholine
    Patent number: 4663455
    Abstract: There is disclosed a process for the preparation of N,N'-tetrathiodimorpholine wherein an admixture of morpholine and elemental sulfur is oxidized with air or oxygen in the presence of iron salts or iron complexes in combination with zinc compounds such as ZnCl.sub.2 and ZnO to yield N,N'-tetrathiodimorpholine.
    Type: Grant
    Filed: September 4, 1986
    Date of Patent: May 5, 1987
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Angelo Bergomi, Joseph A. Kuczkowski
  • Process for preparing N-polythiodimorpholines
    Patent number: 4656266
    Abstract: This invention relates to a new process for the preparation of N-polythiodimorpholines wherein morpholine and elemental sulfur in an alcohol mixture are oxidized with an alkali metal hypohalite or an alkaline earth metal hypohalite or N-chloromorpholine to yield N-polythiodimorpholines. The process produces N-polythiodimorpholines without the use of corrosive or toxic chemicals and the product is an economical substitute for conventional rubber curatives.
