Selective hydrogenation of dimethyl terephthalate to dimethyl 1,4‐cyclohexanedicarboxylate over zeolite‐supported Ru catalysts

The Canadian Journal of Chemical Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 2, 2025

Abstract Dimethyl 1,4‐cyclohexanedicarboxylate (DMCD) is an important chemical product, which widely used in the synthesis of polyester resins, polyamides, and plasticizers. It generally prepared via dimethyl terephthalate (DMT) selective hydrogenation. Herein, zeolite (ZSM‐5‐25/50/100, ZSM‐35, MOR, β)‐supported Ru catalysts were employed for DMT Compared to other zeolites, MOR‐supported showed best performance (DMT conversion: 100%, DMCD selectivity: 81.67% at conditions 180°C, 4 MPa H 2 , 3 h, 2‐propanol as solvent, m(DMT):m(Cat.) = 5:1). After optimizing reaction conditions, conversion selectivity finally reached 100% 95.09%, respectively, 140°C, 6 ethyl acetate 2.5:1. Furthermore, Ru/MOR exhibited good reusability with no significant decrease after 5 cycles. The comprehensively characterized by X‐ray diffraction (XRD), N ‐physisorption, transmission electron microscopy (TEM), ‐TPR, NH temperature‐programmed desorption (NH ‐TPD), photoelectron spectroscopy (XPS), inductively coupled plasma atomic emission spectrometry (ICP‐OES), CO pulse experiment. results indicated that had higher dispersion stronger metal–support interaction. Moreover, greater specific surface area larger pore size, enhancing adsorption efficiency reactants.

Pt AlOOH/C Catalyst for Highly Efficient and Selective Hydrogenation of Nitroarenes

ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(10)

Published: March 1, 2025

Abstract Aromatic amines as important intermediates for chemical production have applications in industry such plastics, rubber processing, herbicides, dyes, and pharmaceuticals. Catalytic hydrogenation of nitroarenes is the main synthetic method producing aromatic amines. This work designs synthesizes a highly efficient selective catalytic catalyst (Pt‐AlOOH/C) using hydrothermal impregnation methods. The Pt‐AlOOH/C catalysts with different loadings (1.0, 0.1, 0.05 wt%) are successfully obtained by changing amount Pt precursor. results show that 1%Pt‐AlOOH/C had best performance, achieving 97.6% conversion 4‐nitroacetophenone 96.0% selectivity to p ‐aminophenone under following reaction conditions 0.5 h, 25 °C, pressure 2.0 MPa. one ─NO 2 also provides excellent activity high being hydrogenated other (for example, 2‐chloronitrobenzene, 2‐bromonitrobenzene, ‐nitrophenol, 1,3‐dinitrobenzene, ‐nitrobenzonitrile) reactions quite mild conditions. characterization nanoparticles dispersion uniformly loaded on AlOOH/C support.
