Abstract:: Using V,O, as main active component, silica gel as carrier, the cocatalyst selection was carried outby taking the conversion of the naphthalene and the selectivity of 1 ,4-naphthoquinone as criterion, it was deter.mined that $n$0, , sodium borate was main cocatalyst. Furthermore , the proper quantity of stannous sulfate added in catalyst was determined to be 1.8 96 by mass fraction at the ratio of potass to vanadium of 3. 17 in mole.Reaction based on this catalyst caused 1 ,4-naphthoquinon yield of more than 90% , and its selectivity of almost10096 . Basification of catalyst made the selectivity of 1 ,4-naphthoquinone increase by 15% on average.
