摘要： The process and the system are used for carrying out the quench-cooled, vapor-phase polymerization of olefin monomer in a horizontally disposed reactor vessel which comprises contacting olefin monomer, or a mixture of olefin monomers, with a polymerization catalyst system in the presence of hydrogen in the reactor vessel to form a polymer product. The improvement comprises introducing a titanium-containing catalyst component of the catalyst system into the top side of the reactor vessel at a point adjacent to the upstream end of the reactor vessel and introducing a cocatalyst plus modifer component of the catalyst system into the top side of the reactor vessel at a distance, downstream of the point of introduction of the titanium-containing catalyst component, which is equal to 25% of the inside diameter of the reactor vessel.

摘要： An oxidation process in which a metal nitro complex transfers an oxygen atom from the nitro ligand to a substrate; especially such process conducted cyclically or catalytically using molecular oxygen as the oxygen source. Metal nitrosyl complex is formed as a coproduct together with an oxidation product of the substrate. In a cyclic process, nitrosyl ligand of the metal nitrosyl coproduct is reoxidized by molecular oxygen in presence of a monodentate base such as pyridine to nitro ligand; and the nitro complex, thus regenerated, can be used again to oxidize the substrate. In a catalytic process, using an activator such as a Lewis acid with alcohols or divalent palladium with olefins, elemental oxygen maintains a concentration of nitro ligand in the reaction mixture. In particular the metal is a Group VIII metal, especially cobalt and the ligand is saloph or tetraphenylporphyrin.

Preferably the rhodium complex is formed with a bipyridyl ligand attached to polystyrene beads, whereby to assure that rhodium is not carried into the hydrogen peroxide production side of the cell.
