ABSTRACT:
The present invention relates to a process for the catalytic amination of 1.degree. and 2.degree. alcohols and diols wherein an amine is reacted with an alcohol or diol in the presence of a non-acidic cationic hydroxyapatite catalyst. A typical reaction includes the amination of ethanol with piperidine to form N-ethylpiperidine. The hydroxyapatite catalyst provides high conversion and selectivity toward the N-alkylated product. Product selectivity can be controlled by adjusting the ratio of cation to phosphorus in the hydroxyapatite catalyst.
