A process for the oxydehydrogenation of ethane to ethylene in a reaction system of open series connected stages, includes changing the total water and acetic acid content in the output gaseous stream after at least one stage other than the last stage of the series.

Process for oxydehydrogenation of ethane to ethylene

A process for low temperature oxydehydrogenation of ethane to ethylene uses an improved supported catalyst produced by impregnating the support with the soluble portion of a precursor catalyst solution and then activating the impregnated support. The activated impregnated support provides good selectivity to ethylene and avoids the problems which can arise from impregnation of the support with the soluble and insoluble portions of a precursor catalyst solution.

Process for preparing a supported catalyst for the oxydehydrogenation of

Alkadienols are prepared by reacting a conjugated diolefin, such as butadiene, with water in the presence of palladium or platinum catalyst and in the presence of solvents. The addition of carbon dioxide to the reaction mixture greatly increases the yield of alkadienols. The products can be hydrogenated to saturated alcohols, useful for making plasticizers.
