Abstract: A polyamide is produced by polymerizing at least one of alpha, beta unsaturated carboxylic acid, an ammonium salt of an alpha, beta unsaturated carboxylic acid, an alpha, beta unsaturated nitrile and water, a beta-amino propionic acid or alkyl derivative thereof and an alpha, beta unsaturated amide and ammonia in the presence of a catalyst containing cobalt. Preferred catalysts comprise cobaltous carboxylates and cobaltic salts of the enol of beta-di-ketones.

Abstract: Alkenes and/or alkadienes are oxidized with molecular oxygen in the presence of an antimony catalyst to produce oxole compounds, such as furan, without substantial conversion of the oxole compounds to undesirable products. The catalyst preferably has the formula
A a D b Sbc Pd O x
wherein A is one or more of the following elements:
Fe, Co, Ni, U, Sn, Mn, La, and rare earth elements; and
D is one or more of the following elements:
Ag, Cu, Mo, V, W, Bi, Te, As, Se, Cr, Zr, Pb, Nb, Ti, Zn, Cd, alkaline earth elements and alkali metal elements; and
wherein a is 0 - 10;
bisO-10;
c is 1-10;
d is 0-20; and
x is the number of oxygens required to satisfy the valence requirements of the other elements present.
In a particular embodiment butadiene is converted to furan by contacting it with air in the presence of a catalyst comprising an oxide complex of antimony and phosphorous.
