Abstract: Catalytic amination of isopropanolamine and ammonia to 1,2-propanediamine over Raney Ni with potassium carbonate as the additive was reported. Characterization of N₂ adsorption–desorption and XRD were performed to reveal the textural and structural properties of the catalysts. With the additive of potassium carbonate, the selectivity of 1,2-propanediamine was improved, while the side generation of 2,5-dimethylpiperazine was suppressed. The catalytic reaction parameters were optimized and the yield of 1,2-propanediamine reached 80% under the optimized reaction condition.

Keywords: Isopropanolamine ; 1,2-Propanediamine ; Raney nickel ; Potassium carbonate ; Reductive amination
