from CuNi phyllosilicates were synthesized, characterized, and tested
in the selective hydrogenation of adipic acid to 1,6-hexanediol. The
reduction of the CuNi phyllosilicate allows finely dispersed Cu0 and Cu+ on the surface. The reduced Cu36Ni5PS catalyst was found to have a higher turnover frequency
for the selective hydrogenation of adipic acid than the reduced Cu41PS, Cu40Ni1PS, and Cu31Ni10PS catalysts. This catalyst is also effective at hydrogenation
of succinic acid, glutaric acid, butyric acid, pentanoic acid, and
hexanoic acid to their respective alcohols. The higher activity of
the reduced Cu36Ni5PS catalyst is attributed
to a higher oxidation state of Cu cations.
