| titleOfInvention | Hydrogenation of cyanopropionaldehyde acetal containing cyanopropionaldehyde |
| abstract | PROBLEM TO BE SOLVED: To provide an improved method for catalytic hydrogenation of cyanopropionaldehyde alkyl acetal (CPAA) for producing aminobutyraldehyde alkyl acetal. The method comprises hydrogenating a cyanopropionaldehyde alkyl acetal by contacting the cyanopropionaldehyde alkyl acetal with hydrogen in the presence of a nickel or cobalt catalyst under conditions to reduce the nitrile group to a primary amine. The improvement is to carry out hydrogenation of a cyanopropionitrile dialkyl acetal feedstock containing impurity levels of cyanopropionaldehyde in the presence of ammonia or primary amines and alkali metal hydroxides. is there. |
