Process for preparation of wax range linear alpha olefins
Abstract
Abstract AN ETHYLENE GROWTH PROCESS FOR OBTAINING REACTION PRODUCT MIXTURES RICH IN LINEAR C22 TO C200 WAX RANGE OLEFINS, ESPECIALLY LINEAR ALPHA OLEFINS OF THE C20 TO C200 CARBON NUMBER RANGE. AN ETHYLENE OLIGOMERIZATION REACTION IS CONDUCTED IN A NONPOLAR DILUENT IN THE PRESENCE OF AN OLIGOMERIZATION CATALYTIC MIXTURE CONSISTING OF A TRANSITION METAL HALIDE AND AN ORGANO ALUMINUM HALIDE, PREVIOUSLY MODIFIED BY TREATMENT WITH AN ORGANIC PHOSPHITE OR PHOSPHINE COMPOUND TO YIELD SAID WAX RANGE OLEFINS WITHOUT SUBSTANTIAL PRODUCTION OF HIGH MOLECULAR WEIGHT POLYMERS. PRESSURE AND TEMPERATURES ARE SELECTED TO MAINTAIN A MOLAR RATIO OF ETHYLENE TO PRODUCT OLEFINS SUFFICIENT TO MINIMIZE COPOLYMERIZATION OF THE PRODUCT OLEFINS, TEMPERATURES, RANGING GENERALLY UP TO ABOUT 75*C.
