摘      要：The selective oxidation of para-xylene(PX)to terephthalic acid(TPA)has received increasing attention due to the industrial applications of ***,the oxidation of the C(sp^(3))‒H bond of PX is still a main challenge because of the higher bond dissociation ***,an efficient photocatalytic system for the oxidation of PX to TPA was developed by using tetrabutylammonium decatungstate(TBADT)photocatalyst using atmospheric oxygen as oxidant and 365 nm LED light *** resulting TPA product was easily separated from the post-reaction solution through simple filtration treatment with a 93.4%yield in CH3CN(37.5%1 mol L^(‒1) HCl)solvent after 19-h *** the easy separation of TPA and the excellent recycling stability of TBADT,a continuous-flow photoreactor was successfully designed with promising prospect for potential industrial *** studies elucidated that the presence of HCl additive benefits the structural integrity of[W10O32]4−anions and the transition from excited states[W_(10)O_(32)]^(4‒*)to wO active species,leading to enhanced photooxidation performance.
