Appeal No. 95-2331
Application No. 08/127,854
The subject matter on appeal relates to a process for the
production of an alkyl formamide wherein the improvement
comprises utilizing a polyethylene glycol as a solvent and
utilizing an alkali metal or alkaline earth metal alkoxide of
a polyethylene glycol, propylene glycol, polyethylenepropylene
glycol or mixtures thereof as the catalyst. This appealed
subject matter is adequately illustrated by independent claim
1 which reads as follows:
1. In a process for the production of an alkyl
formamide, wherein a gas-containing carbon monoxide is reacted
at elevated temperature and pressure in a reaction zone with a
nitrogen- containing compounds [sic, compound] selected from
the group consisting of ammonia, a primary alkylamine and a
secondary alkylamine, in the presence of a solvent and a
catalyst, the improvement which comprises:
utilizing a polyethylene glycol as a solvent and
utilizing an alkali metal or alkaline earth metal
alkoxide of a polyethylene glycol, polypropylene
glycol, polyethylenepropylene glycol or mixtures
thereof as the catalyst.
