摘要

Abstract Vanadium phosphate oxide (VPO) catalysts derived from VOHPO 4· 0.5 H 2 O and VO (H 2 PO 4) 2 precursors showed improved rates in the catalysed liquid phase oxidation of p-cymene. Both catalysts showed high performance with conversions of up to 30% achieved within 3 h with a selectivity towards the tertiary cymene hydroperoxide (TCHP) of 75–80% when compared to lower conversions and poorer TCHP selectivity in the non- ...
