Appeal No. 1996-1288
Application No. 08/227,576
This is a decision on an appeal from the refusal of the
examiner to allow claims 2 through 6, 8 through 17, 19, 21
through 25 and 27 through 32 as amended subsequent to the
final rejection. These are all of the claims pending in the2
application.
The subject matter on appeal relates to a process for
removal of sulfonated and unsulfonated organic phosphorous
compounds from a starting solution which is a reaction product
of sulfonation of aryl phosphines by sulfuric acid. The
process comprises extraction of the sulfuric acid with 40 to
90 mol of a principal amine which is sparingly soluble or
insoluble in water. This appealed subject matter is
adequately illustrated by independent claim 28 which reads as
follows:
28. A process for removal of sulfonated and unsulfonated
organic phosphorus compounds from a starting solution which is
a reaction product of sulfonation of aryl phosphines by
sulfuric acid, which process comprises extraction of said
sulfuric acid with 40 to 90 mol, per mol of the sulfonic acid
radicals of said sulfonated organic phosphorus compounds
2By an apparently inadvertent oversight, the amendment-
after-final filed March 29, 1995 has not been clerically
entered notwithstanding the entry-authorization of the
examiner in the advisory action mailed April 11, 1995. This
oversight should be corrected upon return of the application
to the jurisdiction of the examiner.
