Alkyl Amines are typically made by amination of alcohols or aldehydes. For methyl amines, alumosilicates and zeolites are used as catalysts. By amination of C2-C5 alcohols generally short-chain alkyl amines are produced. Ni- and Co catalysts are used. For C6-C18 amines our copper catalysts or copper chromites are preferred.
Nitrile Hydrogenation
is basically conducted with long-chain nitriles, especially fatty nitriles. Nickel catalysts are used for slurry application. For fixed-bed application we recommend tablets and extrusions of our NiSAT® -series.
Hydrogenation of nitrobenzene to aniline
is carried out either in a slurry process based on nickel catalysts, or in isothermal gas phase processes based on copper catalysts. The silica-based reduced NiSAT®powders exhibit excellent activity for slurry application and good filtration properties. By use of these catalysts dearomatisation and side reactions are minimised.
N-Alkylation
and reductive N-alkylation reactions are performed with our nickel and cobalt catalysts in slurry phase and fixed beds.
