Michael E Ford, John N Armor: One step production of low salt vinylamine polymers. Air Products and Chemicals, Mark L Rodgers, William F Marsh, February 13, 1996: US05491199 (5 worldwide citation)

Salt-free poly(vinylamine) and vinylamine copolymers are formed by heating N-vinylformamide or N-vinylformamide copolymers to a temperature from about 50.degree. to 225.degree. C. in an aqueous medium in the presence of a catalyst comprising a transition metal which is a member of either the first t ...

John N Armor: Direct oximation of ketones using gallia catalysts. Allied Chemical Corporation, Robert A Harman, September 30, 1980: US04225511 (2 worldwide citation)

Ammonia, oxygen e.g., as air, and a ketone react in contact with a gallium oxide catalyst at temperatures such as 50.degree.-500.degree. C., especially such catalyst obtained by heating hydrated gallium nitrate in air at about 350.degree. C. for several hours. The oximes have known utilities, includ ...
