摘要: Cupreous catalysts prepared by reducing a mixture consisting essentially of copper oxide in combination with certain metal oxides have been discovered to be excellent heterogeneous catalysts for the hydration of nitriles to the corresponding amide....
The relative concentration of metal salt present in a starting mixed salt solution influences the conversion rate associated with a catalyst prepared as taught by this invention when used in the hydrolysis of nitrile to amide in accord with the process of this invention. A presently most preferred...
process for the preparation of amides by enzymatic hydrolysis of nitriles. In order to study the structure-reactivity relationship in the intramolecular catalyzed hydrolysis of amide, a series of aliphatic hydroxyamides was subjected to acid-catalyzed hydrolysis. Paper chromatogram verified that the hydro...

The hydratase/amidase system catalysed the hydrolysis of D,L-aminonitriles into racemic mixtures of amino acids. Strain CH5 is able to produce high concentrations of malonic acid monoamide from malononitrile and malonamide. The other isolate, Alcaligenes sp. (strain I4), can convert high ...

The amidase from Rhodococcus rhodochrous J1, which hydrolyzes an amide to an acid and ammonium, was surprisingly found to catalyze the hydrolytic cleavage of the C-N triple bond in a nitrile to form an acid and ammonium stoichiometrically. The amidase exhibited a Km of 3.26 mM for benzonitrile...
The unusual kinetic parameters for the latter complex are attributed to neighboring-group participation by the amide group.doi:10.1002/chin.198212325BALAHURA, R. JPURCELL, W. LJohn Wiley & Sons, LtdChemischer Informationsdienst
