Abstract

The decomposition of 1,3-diisopropylbenzene dihydroperoxide (DHP) obtained by the catalytic oxidation of 1,3-diisopropylbenzene (DIPB) is known as the main industrial process to produce resorcinol. A new catalyst of highly dispersed Fe in P-doped N-C (Fe-N/P-C) was synthesized using a ligand-assisted method, and was applied for the peroxidation of DIPB. SEM, TEM and HAADF-STEM revealed that Fe is uniformly dispersed on N/P-C. XRD, Raman spectra, N₂ adsorption/desorption, XPS and O₂-TPD showed that doping of P species in N-C leads to form more mesopore and increases the disorder degree, providing more active sites for the activation of tertiary C-H bonds in DIPB. The conversion of DIPB was 97.8 % and the yield of DHP was 67.2 % under mass of Fe-N/P-C to DIPB was 1.0, reaction temperature was 90°C, oxygen flow rate was 100 mL/min, and reaction time was 8 h. The investigation of radical quenching and mass spectrometry suggested that the increased oxidation rate is attributed to the involvement of Fe-N/P-C in both chain initiation and chain propagation.

期刊介绍： Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications. Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
