Abstract: 1404028 Particulate Zeigler catalyst-wax compositions BADISCHE ANILIN- & SODAFABRIK AG 12 Dec 1972 [13 Dec 1971] 57257/72 Heading C3P A Zeigler catalyst, preferably supported on an inorganic carrier, is obtained in particulate form embedded in a wax by (a) forming a melt at 40‹ to 120‹ C. of a wax melting above 30‹ C. and the Zeigler catalyst, (b) passing the melt continuously, e.g. as a stream of droplets, into a liquefied gas, inert to the catalyst and wax, having a temperature of -30‹ to -200‹C. and in motion at a modified Reynolds number of from 3À4.10 3 to 5À10 4 , and (c) recovering the particulate catalyst composition from the liquid, e.g. by allowing the gas to evaporate. The product has a particle diameter in the range 0À1 to 5 mm. and may be used for polymerization of olefins, e.g. ethylene and propylene, the catalyst being freed from the wax by melting. In examples, waxes used are paraffin wax (m.p. 69‹ to 73‹ C.) or a mixture thereof with a polyvinyl ether wax (m.p. 56‹ C), the liquefied gas is nitrogen at - 196‹ C. or liquefied propane at -78‹ C., and the catalysts are magnesium oxide- or magnesium aluminium oxide-supported mixtures of titanium tetrachloride and aluminium triethyl or diethyl aluminium chloride.
