Title
Oxidation of cyclohexane to adipic acid catalyzed by Mn-doped titanosilicate with hollow structure
Abstract

•Mn-HTS exhibits high selectivity for the oxidation of cyclohexane to adipic acid.•The catalyst can be reused and easily separated from the reaction system.•Using molecular oxygen as oxidant without any initiator and solvent.

One-step oxidation of cyclohexane to adipic acid (AA) was carried out at 413 K over manganese-doped titanium silicalite with hollow structure (HTS) using oxygen as oxidant without any initiator or solvent. The catalyst exhibited high conversion (13.4%) and reasonable product (AA) selectivity (57.5%). Hot-separation and catalyst-recycle tests proved that the catalyst acted as a heterogeneous one and it could be reused four times without losing its activity. The synthesized materials were characterized by N2 adsorption–desorption isotherm, FT-IR, UV–vis and XPS techniques.
