The Effect of PreparationConditions on the Performanceof Hydrogenolysis of Furfurylamine to 5‑Amino-1-Pentanol overPt/ZrO₂ Catalyst

5-Amino-1-pentanol is an important pharmaceutical intermediate used in the synthesis of anti-inflammatory and anticancer drugs. The direct hydrogenolysis of furfurylamine to 5-amino-1-pentanol has the advantages of a simple process route and high atom utilization. In this paper, for Pt/ZrO₂ catalysts, the effects of different Pt loading and calcination temperatures on catalyst activity, selectivity, and surface properties such as Pt nanoparticle size, acidity and alkalinity, and the ratio of Pt⁰/(Pt⁰+Pt²⁺) were investigated. Through the study of the relationship between catalyst preparation conditions, furfurylamine hydrogenolysis reaction performance, and surface properties, it was found that moderate Pt nanoparticle size, higher Pt⁰/(Pt⁰+Pt²⁺) ratio, and more acidic sites favored furfurylamine hydrogenolysis. The higher number of basic sites favors the dispersion of Pt metal. The results of in situ FTIR show that the amino group of furfurylamine is adsorbed on the acidic site of Pt/ZrO₂, and the furan ring is adsorbed on Pt nanoparticles, which is beneficial to the hydrogenolysis of furfurylamine.
