Process for preparing olefin disproportionation catalysts

Abstract

Abstract A PROCESS FOR PREPARING A CATALYST WHICH CONSISTS ESSENTIALLY OF CONTACING A CARBENE COMPLEX SELECTED FROM THE GROUP CONSISTING OF COMPLEXES HAVING THE FORMULAS A(M(CO)5COR) AND M(CO)5(COR)R'' WHEREIN A IS A UNIPOSITIVE CATION SLECTED FROM THE GROUP CONSISTING OF LI, NA, K AND CATIONS HAVING THE GENERAL FORMULA J4Q WHEREIN Q IS A GROUP V ELEMENT AND J IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND C1 TO C30 HYDROCARBYL RADICALS, M IS A GROUP VI-B METAL, R AND R'' ARE C1 TO C30 HYDROCARBYL RADICALS, WITH ALY3 OR AN ORGANOMETALLIC HALIDE SELECTED FROM THE GROUP CONSISTING OF COMPOUNDS HAVING THE GENERAL FORMULA R"NDYM WHERE R" IS CHOSEN FROM THE GROUP CONSISTING OF C1 TO C30 HYDROCARBYL RADICALS, D IS A METAL SELECTED FROM THE GROUP CONSISTING OF GROUP II AND GROUP III OF THE PERIODIC TABLE OF THE ELEMENTS, Y IS A HALIDE, AND N IS AN INTERGER OF FROM 1 TO 3 AND M IS AN INTERGER OF FROM 0 TO 3, THEIR TOTAL EQUAL TO THE VALENCE OF D, THE MOLAR RATIO OF ORGANO-METRALLIC HALIDE TO GROUP VI-B METAL BEING FROM ABOUT 0.5:1 AND 50:1, AT A TEMPERATURE OF FROM ABOUT- 100 TO +150*C. AND A PRESSURE OF FROM ABOUT 0.1 TO 1000 ATMOSPHERES, WHEREBY A CATALYST IS FORMED. THE RESULTING CATALYST IS USEFUL FOR DISPROPORTIONATING OLEFINS.
