1279887 Catalyst system OLIN CORP 21 Nov 1969 [21 Nov 1968] 57069/69 Addition to 1245480 Heading B1E [Also in Division C2] A catalyst system comprises either 1(a) at least one heteroaromatic compound having 5 or 6 members in the ring, only nitrogen and carbon in the ring, no more than two nitrogen atoms in the ring and at least two double bonds in the ring, or a derivative of such a compound, (b) at least one noble metal halide or oxide, and (c) at least one halide of a non- noble metal from groups IVa, Va, VIa, VIIa, IIb, IVb and Vb; or 2- a complex of a compound of (a) with a halide of (b) and at least one halide of (c); or 3- a complex of a halide of (b) with a halide of (c) and at least one compound of (a). Many particular aromatic compounds, noble metal halides and non-noble metal halides are specified. Specified noble metals are ruthenium, rhodium, palladium, osmium, iridium, platinium, silver and gold and specified non-noble metals are titanium, zirconium, vanadium, tantalum, chromium, manganese, iron, zinc, mercury, germanium, tin, lead, arsenic, antimony and bismuth. The catalyst system may also contain one or more oxides of metals of groups Va and VIa. The preferred ratio of the aromatic compound to the anion of the noble metal halide and the preferred ratio of the aromatic compound to the anion of the non-noble metal halide is between 0.01:1 and 10:1. The catalyst may be self-supported or deposited on a carrier, those specified being alumina, silica, carbon, barium sulphate, calcium carbonate, asbestos, benitonite, diatomaceous earth and fullers earth. Examples describe (a) Pd Cl 2 with isoquinoline and one of SnCl 4 , GeCl 4 , FeCl 3 , ZrCl 4 , SnCl 2 , SbCl 3 , BiCl 3 , HgCl 2 , ZnCl 2 , PbCl 2 , VCl 3 , TaCl 3 , CrCl 3 , MnCl 2 , MoCl 4 ; (b) PdCl 2 with pyridine and GeCl 4 ; (c) PdCl 4 with pyridine and GeCl 4 or isoquinoline. and SnCl 4 ; (d) RhCl 3 with pyridine and SnCl 2 or isoquinoline and BiCl 3 or CrCl 3 ; (e) PdZnCl 4 with isoquinoline, PdSnCl 4 with 7,8-Benzoquinoline and PdBiCl with 4-phenylyridine. |
