Reaction Steps

A 500 mL autoclave of an electromagnetic induction rotary agitation type was charged with 150 g (0.55 mol) of stearyl alcohol and 3 g of the catalyst (G) produced in Preparation Example 6 (2.0% by mass on the basis of the raw alcohol), and then the contents of the autoclave were heated to 220° C. in a hydrogen atmosphere (0 MPaG) while stirring (at 1000 rpm). Then, while flowing ammonia and hydrogen through the autoclave at rates of 19.1 g (1.1 mol)/h and 2.6 L (0.12 mol)/h, respectively, so as to maintain the reaction pressure at a constant value of 2.0 MPaG, the reaction was conducted for 3 h. The resultant reaction product was filtered to remove the catalyst therefrom, and then subjected to gas chromatography to analyze a composition thereof. As a result, it was confirmed that the conversion of the raw alcohol was 96.0%, the selectivity to lauryl amine was 78.1%, the amount of dilauryl amine produced is 13.4%, and the amount of the other by-products produced was 7.6%.
