  • Process for preparing N-alkyl-alkylene-diamines
    Patent number: 4373107
    Abstract: A process for preparing an N-alkylene-diamine by contacting an alkylene diamine with an aliphatic aldehyde in a reaction solvent in the presence of hydrogen under pressure and an platinum group metal, which comprises gradually adding the aliphatic aldehyde to the alkylene diamine. The process according to the present invention provides a high conversion of the alkylene diamine and a high selectivity to the N-alkyl-alkylene-diamine.

  • Selective oxoamination process
    Patent number: 4299985
    Abstract: This invention concerns the synthesis of linear alkyl primary amines from a-olefins via an oxoamination process comprising (a) hydrogen and carbon monoxide addition to olefinic substrates to obtain aldehyde-containing compounds in the presence of ligand-stabilized platinum(II) halide catalysts with Group IVB metal halide cocatalysts, and (b) reductive amination of said aldehydic intermediates in the presence of oxide-supported, nickel catalysts.

  • Production of amines
    Patent number: 4292242
    Abstract: Aminomethylation of olefins which employs a homogeneous catalyst which is a solution in a suitable solvent of mixed ruthenium and iron carbonyls. The overall reaction may be represented as follows: ##STR1## where R.sub.1 and R.sub.2 are hydrogen or essentially hydrocarbon groups. The reaction proceeds by way of an aldehyde intermediate. Accordingly, the starting material may be an aldehyde instead of an olefin.
