them patentably distinct from claims 1 through 22 (hereinafter, Group I). Accordingly, for
purposes of this appeal, we will consider the issues as they apply to claims 1 and 23,
which are representative of each of the claim groupings. Claims 1 and 23 read as follows:
1. A process for the production of aryl carbonates comprising reacting an aromatic
monohydroxy compound with at least one member selected from the group consisting of
phosgene and chlorocarbonic acid ester of an aromatic monohydroxy compound, at a
temperature of 50 to 350EC in the presence of active carbon as catalyst.
23. A process for the production of aryl carbonates comprising reacting an
aromatic monohydroxy compound with at least one member selected from the group
consisting of phosgene and chlorocarbonic acid ester of an aromatic monohydroxy
compound at, a temperature of 50 to 350EC, in the presence of suspended active carbon
catalyst, said catalyst being present in an amount of 5 to 100% relative to the weight of
said monohydroxy compound.
