Reaction Conditions:

with ammonium hydroxide;cerium(III) nitrate hexahydrate in water at 210; for 3.5 h;Inert atmosphere;

Steps:

5 Example 5
The 50gCe (NO₃)₃· 6H₂O was dissolved in 250 mL of deionized water, 10% aqueous ammonia was added dropwise to the resulting solution at room temperature, and the mixture was stirred dropwise until pH = 10.The precipitate was collected by filtration and deionizedAfter drying at 80 for 8 h, the catalyst was calcined at 400 for 3 h to obtain the ceria catalyst A, which was characterized by XRD and JCPDS (4- 0593). In a stirred reactor, 400 g of myristic acid and catalyst A in an amount of 2% (i.e., 8 g) in mass were charged, and the mixture was heated to 210 ° C in a nitrogen atmosphere, passed through dimethylamine and maintained at 39-43 L / h (Corresponding to 1.0 to 1.1 mol / L per 1 mol of myristic acid), and the total reaction time was 3.5 h.After completion of the reaction, the catalyst was removed by suction filtration to obtain the productOf the acid value was 0.4 and the conversion was 99.8%. The content of the fatty acid amide obtained by distilling off the excess dimethylamine from the product under reduced pressureIs 99% or more.
