Abstract
A process for the conversion of at least one olefinic organic compound by disproportionation, proportionation, and/or isomerization, in which an olefin conversion catalyst is exposed to electromagnetic radiation prior to and/or during contact of the organic compound with the catalyst. The catalyst may also be pretreated with ethylene, propylene and/or butene during exposure to radiation or the olefinic compound may be pretreated by contact with magnesium oxide while exposing the magnesium oxide to radiation.
Claims45
In a process for the redistribution of at least one olefinic bond of at least one reactant olefinic organic compound which comprises reacting said at least one reactant olefinic organic compound in the presence of a solid catalyst comprising a compound selected from the group consisting of transition metal oxides, transition metal compounds convertible to oxides by calcination and mixtures thereof deposited on an essentially inert solid support, at a temperature, at a pressure and for a time sufficient to effect said redistribution of at least one olefinic bond, the improvement comprising;
- exposing said solid catalyst to electromagnetic radiation having a wavelength of at least about 1000 A in the presence of at least one olefinic organic compound selected from the group consisting of at least one reactant olefinic organic compound, at least one olefinic organic compound other than a reactant olefinic organic compound and mixtures thereof, said exposing of said solid catalyst to electromagnetic radiation being carried out prior to said reacting of said at least one reactant olefinic organic compound, during said reacting of said at least one reactant olefinic organic compound or both prior to and during said reacting of said at least one reactant olefinic organic compound.
A process for the redistribution of at least one olefinic bond of at least one reactant olefinic organic compound comprising contacting said at least one reactant olefinic organic compound with magnesium oxide, reacting the thus contacted at least one reactant olefinic organic compound with a catalyst active for said redistribution of at least one olefinic bond of at least one reactant olefinic organic compound, at a temperature, at a pressure and for a time sufficient to effect said redistribution of at least one olefinic bond of at least one reactant olefinic organic compound, at least one of said magnesium oxide and said catalyst being exposed to electromagnetic radiation having a wavelength of at least 1000 A in the presence of at least one olefinic organic compound selected from the group consisting of at least one reactant olefinic organic compound, at least one olefinic organic compound other than a reactant olefinic organic compound and mixtures thereof, prior to said contacting and said reacting, during said contacting and said reacting or both prior to and during said contacting and said reacting.
In a process for the isomerization of at least one reactant olefinic organic compound including reacting said at least one reactant olefinic organic compound with a catalyst active for the isomerization of said at least one reactant olefinic organic compound at a temperature, at a pressure and for a time sufficient to effect said isomerization of said at least one reactant olefinic organic compound, the improvement comprising;
- exposing said catalyst to electromagnetic radiation having a wavelength of at least about 1000 A in the presence of at least one olefinic organic compound selected from the group consisting of at least one reactant olefinic organic compound, at least one olefinic organic compound other than a reactant olefinic organic compound, said exposing of said catalyst to electromagnetic radiation being carried out prior to said reacting of said at least one olefinic organic compound, during said reacting of said at least one reactant olefinic organic compound or both prior to and during said reacting of said at least one reactant olefinic organic compound.
