Process for producing linear alpha olefins

Abstract

Abstract WHEREIN P IS PHOSPHORUS AND R, R'' AND R" BEING THE SAME OR DIFFERENT ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, ALKYL, CYCLOALKYL AND ALKOXY CONTAINING FROM 1 TO 20 CARBON ATOMS, IN THE PRESENCE OF A POLAR DILUENT SELECTED FROM THE GROUP CONSISTING OF AROMATIC, HALOGENATED AROMATIC AND HALOGENATED ALIPHATIC COMPOUNDS AT A TEMPERATURE BELOW 75*C. AT PRESSURE SUFFICIENT TO LIQUEFY THE ETHYLENE. R-P(-R'')-R" A PROCESS FOR PREPARING LINEAR ALPHA OLEFINS HAVING AN AVERAGE MOLECULAR WEIGHT RANGING FROM ABOUT 70 TO ABOUT 300 BY POLYMERIZING AN ETHYLENE CONTAINING GAS IN THE PRESENCE OF A HOMOGENEOUS CATALYST FORMED UPON REACTING A TRANSITION METAL HALIDE SELECTED FROM THE GROUP CONSISTING OF TIX4, TIX3OR'' AND TIX3OOCR'' WHEREIN X IS SELECTED FROM THE GROUP CONSISTING OF CHLORINE AND BROMINE AND R'' IS SELECTED FROM THE GROUP CONSISTING OF ALKYL, ALLYL, ARALKYL AND CYCLOALKY WITH AN ALUMINUM ALKYL HALIDE COMPOUND CHARACTERIZED BY THE FORMULA AIRNX3-N WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF ALKYL, ARALKYL AND CYCLOALKY, X IS SELECTED FROM THE GROUP CONSISTING OF CHLORINE, BROMINE AND IODINE AND N IS LESS THAN 2, ALONG WITH FROM 5% TO ABOUT 50 MOL PERCENT BASED ON THE MOLES OF TRANSITION METAL HALIDE PRESENT IN THE CATALYTIC MIXTURE OF A MODIFIER CHARACTERIZED BY THE FORMULA
