Appeal No. 94-3251
Application 08/071,690
The subject matter of the appealed claims relates to a two-
step process for the preparation of an amine. Claim 1, the only
independent claim, is illustrative of the appealed claims and
reads as follows:
1. A process for the preparation of an amine of the formula
CH -NH-CH -R, wherein R is an aliphatic radical having 1 to 3
3 2
carbon atoms, comprising a first reaction of an aldehyde of the
formula R-CHO with an amine of the formula R'-NH , wherein R' is
2
a straight or branched chain aliphatic radical having 6 to 12
carbon atoms, to produce a Schiff base and water of reaction,
removal of said water, and a second reaction of said base with
methylamine and hydrogen in the presence of a hydrogenation
catalyst.
As indicated on page 3 of appellants' brief, the claims
stand or fall together. Accordingly, we will limit our
consideration to claim 1 in considering the examiner's rejection
of the appealed claims.
The reference relied on by the examiner is :
Terada 44-20322 (Japan) September 2, 1969
Claims 1-22 stand rejected under 35 U.S.C. § 103 as
unpatentable over Terada. We have carefully considered
appellants' position as set forth in the appeal brief and the
examiner's position as set forth in his answer, and we have
decided that we will not sustain the rejection.
