    Abstract: A supported catalyst for the production of carbon monoxide copolymers is obtained by suspending the support in non-polar aprotic solvent, adding a solution of a Group VIIIB, IB or IIB metal complex with bi- or tri-dentate ligand(s) in a polar aprotic solvent, possibly adding non- polar solvent and working up by filtration. A process for the production of linear alternating copolymers of carbon monoxide (CO) and olefinically unsaturated compounds uses an activator compound and a supported heterogeneous catalyst system, which is obtained by: (a) suspension of the support material in a non-polar aprotic liquid (NPAL), (b) controlled addition of a Group VIIIB, IB or IIB metal chelate complex with bi- or tri- dentate ligand(s) as a solution in a polar aprotic liquid, (c) filtration, optionally followed by washing with NPAL and (d) optionally removing liquid residues with inert gas. Alternatively, the mixture obtained from stage (b) may be mixed with NPAL before performing stages (c) and (d) as above. An Independent claim is also included for carbon monoxide copolymers obtained by this process.

    Abstract: THE INVENTION RELATES TO A PROCESS FOR THE PREPARATION OF METHYL FORMATE BY REACTING METHANOL WOTH CARBON MONOXIDE AT A PRESSURE OF FROM 0.5 TO 10 MPA ABS. AND A TEMPERATURE OF FROM 50 TO 150°C IN THE PRESENCE OF A METAL ALKOXIDE AS CATALYST IN A REACTOR, IN WHICH A GAS STREAM IS WITHDRAWN FROM THE REACTOR, ENTRAINED METHYL FORMATE IS REMOVED FROM THIS GAS STREAM BY CONDENSATION, AND ALL OR SOME OF THE REMAINING GAS STREAM IS RETURNED TO THE REACTOR AS CIRCULATING-GAS STREAM AND A MEAN GAS SUPERFICIAL VELOCITY OF FROM 1 TO 20 CM/S IS SET IN AT LEAST ONE REGION OF THE REACTOR IN WHICH THE GAS FLOWS ESSENTIALLY IN ONE DIRECTION.
