Abstract: An on-line method of synthesizing or regenerating catalysts for autothermal oxidation processes, specifically, the oxidation of paraffinic hydrocarbons, for example, ethane, propane, and naphtha, to olefins, for example, ethylene and propylene. The catalyst comprises a Group 8B metal, for example, a platinum group metal and, optionally, a promoter, such as tin, antimony, or copper, on a support, preferably a monolith support. On-line synthesis or regeneration involves co-feeding a volatile Group 8B metal compound and/or a volatile promoter compound with the paraffinic hydrocarbon and oxygen into the oxidation reactor under ignition or autothermal conditions.

Abstract: The instant invention is directed to a process for removing odor from alkylthioethylamine reaction product mixtures having said odor. The process comprises first contacting an alkylthioethanamine reaction product mixture with a neutralizing amount of aqueous alkali metal hydroxide to form an organic phase and an aqueous phase. Next, the organic phase is separated from the aqueous phase. After separation, a sufficient amount of an aqueous hydrohalic acid is added to the organic phase to form an alkylthioethanamine hydrohalide which has reduced odor.
