| titleOfInvention | Process for the manufacture of ethylene polymers by way of Phillips catalysis |
| abstract | The framework is the production of ethene polymers by Phillips catalysis using (1) a supported catalyst which is loaded with chromium, phosphorus and titanium, and (2) a cocatalyst, (1) having been obtained by (1.1) a with chromium , Phosphorus and titanium-laden catalyst precursor is produced from a silicate carrier, a selected chromium compound, a selected phosphorus compound and a selected titanium compound, and then (1.2) the catalyst precursor is heated in an oxygen-containing gas stream. It is characteristic that one uses (1) one that has been obtained by - first in each case in the type and manner - (1.1) first (1.1.1) from (1.1.1.1) a finely divided one produces a suspension of silicate and (1.1.1.2) an inert organic solvent, (1.1.2) then produces a suspension from (1.1.2.1) a finely divided chromium trioxide and (1.1.2.2) an inert organic solvent, (1.1.3) thereupon (1.1.3.1) the suspension resulting from (1.1.2) is combined with (1.1.3.2) a phosphoric acid or phosphoric acid ester, (1.1.4) then (1.1.4.1) the suspension obtained from (1.1.1) with (1.1.4.2) combines the reaction product obtained from (1.1.3), (1.1.5) then (1.1.5.1) combines the suspension formed in (1.1.4) with (1.1.5.2) a titanium acid ester, (1.1.6 ) finally evaporate the suspension obtained in (1.1.5) to dryness, and then (1.2) second (1.2.1) the one obtained from (1.1) The preliminary product is treated with a nitrogen stream, then (1.2.2) the intermediate product obtained from (1.2.1) is heated in an oxygen-containing gas stream, and finally (1.2.3) the intermediate product obtained from (1.2.2) is treated with a nitrogen stream; and as (2) a lithium alkyl. |
