Shaped polymeric transition metal complex catalysts comprising organosiloxane-diphenylphosphine ligands. |
摘要 |
The invention relates to shaped polymeric complexes of metals from sub-group 8 of the Periodic Table with ligands of an organosiloxane copolycondensate (random, block or mixed) which is optionally crosslinked by means of Si-, Ti-, Zr- and/or Al-containing crosslinking agents. This copolycondensate comprises units <IMAGE> and <IMAGE> where R<1> - R<4> are <IMAGE>, in which R<5> is directly P- or N-bonded C1-C10-alkylene, C5-C8-cycloalkylene or <IMAGE>. The ratio between the number of moles of units (II) and the number of moles of bonded metal atoms is from 1:1 to 1000:1, and the ratio between the units (I) and (II) is preferably from 10:90 to 95:5 mol%. The polymeric complex compounds are in macroscopic form as spherical particles having a diameter of from 0.01 to 3.0 mm, a BET surface area of from >0 to 1000 m<2>/g, a specific pore volume of from 0.01 to 6.5 ml/g and a bulk density of from 50 to 1000 g/l. The invention also relates to a number of preparation processes for the substances according to the invention with specific aftertreatment steps, and the use of the polymeric metal complexes as catalysts in organic chemistry. |
