m+p+q equals 2n+2 when the compound is saturated and
acyclic, equals 2n when the compound is saturated
and cyclic or is olefinic and acyclic, and equals
2n-2 when the compound is olefinic and cyclic, using
a catalyst of at least one metal selected rom the
group consisting of rhenium, cobalt, nickel,
ruthenium, rhodium, palladium, osmium, iridium and
platinum supported on carbon which is characterized
by said catalyst containing less than about 200 ppm
phosphorus and less than about 200 ppm sulfur.
Applicant presents a second independent claim that
requires an acid washing step. Claim 24 is reproduced below:
24. A process for the catalytic hydrogenolysis
of a cyclic or acyclic compound having the formula
C H F X wherein n is an integer from 1 to 6, m is an
n m p q
integer from 0 to 12, p is an integer from 1 to 13,
q is an integer from 1 to 13 and each X is
independently selected from Cl and Br, provided that
m+p+q equals 2n+2 when the compound is saturated and
acyclic, equals 2n when the compound is saturated
and cyclic or is olefinic and acyclic, and equals
2n-2 when the compound is olefinic and cyclic, using
a catalyst of at least one metal selected rom the
group consisting of rhenium, cobalt, nickel,
ruthenium, rhodium, palladium, osmium, iridium and
platinum supported on carbon characterized by: (1)
treating the carbon with acid; and (2) subsequently
