Appeal No. 96-1315
Application 08/293,611
The subject matter on appeal is directed to a method for recovering a C1
chlorocarbon from a gaseous mixture by use of a liquid hydrocarbon having an average
molecular weight within a range of about 142 to 422 at a temperature and pressure where
the C is absorbed in the liquid hydrocarbon.
1
All the claims stand or fall together. Claim 1 is illustrative and reads as follows:
1. A process for recovering a C chlorocarbon from a gaseous mixture, the process
1
comprising: contacting a gaseous mixture comprising a C chlorocarbon and a
1
noncondensible gas with an absorbent comprising a liquid hydrocarbon having an average
molecular weight within a range of about 142 to 422 at a temperature and pressure where
the C chlorocarbon is absorbed in the liquid hydrocarbon thereby separating the C1 1
chlorocarbon from the noncondensible gas.
There are no references relied upon by the examiner.
Claims 1-4 and 6-16 stand rejected under 35 U.S.C.§ 112, first paragraph. It is the
examiner’s position that appellants' specification is enabling only for claims limited to the
liquid hydrocarbon having an average molecular weight of about 272, which is the weight
of the liquid hydrocarbon of examples 1 and 2 in the specification. The examiner states
that “[T]here are no other examples of the use of any other type of liquid hydrocarbon nor
[sic: or] of molecular weights which approach the two outer limits of the ‘range of about 142
to 422'” (original emphasis).
We reverse.
