Process utilizing pi base aromatic modified catalyst for wax production
Abstract
Abstract AN ETHYLENE GROWTH PROCESS FOR OBTAINING REACTION PRODUCT MIXTURES RICH IN LINEAR C22 TO C200 WAX RANG OLEFINS, ESPECIALLY LINEAR ALPHA OLEFINS OF THE C40 TO C100 CARBON NUMBER RANGE. AN ETHYLENE OLIGOMERIZATION REACTION IS CONDUCTED IN A DILUENT IN THE PRESENCE OF AN OLIGMERIZATION CATALYST MIXTURE CONSISTING OF A TRANSITION METAL HALIDE AND AN ORGANOLAUMINUM HALIDE, PREVIOUSLY MODIFIED BY TREATMENT WITH A PI BASE COMPOUND, PARTICULARLY A PIBASE AROMATIC COMPOUND, TO YIELD SAID WAX RANGE WITHOUT SUBSTANTIALY PRODUCTION OF HIGH MOLECULAR WEIGHT POLYMERS. PRESSURES AND TEMPERATURES ARE SELECTED TO MAINTAIN A MOLAR RATIO OF ETHYLENE TO PRODUCTS OLEFINS SUFFICIENT TO MINIMI ZE COPOLYMERIZABLE OF THE PRODUCT OLEFINS.
