摘　　要： 以V2O5为主要活性组分,硅胶为载体,使用复合型催化剂,以萘的转化率、1,4-萘醌的选择性和萘醌的收率作为考核指标,通过对助催化剂进行筛选,确定SnSO4、硼酸钠等金属盐为主要助催化剂,n(K)∶n(V)=3.17时,硫酸亚锡的质量分数为1.8%,此时1,4-萘醌收率达90%以上,选择性接近100%,碱处理后催化剂对1,4-萘醌的选择性平均提高了15%左右. Using V2O5 as main active component,silica gel as carrier,the cocatalyst selection was carried out by taking the conversion of the naphthalene and the selectivity of 1,4-naphthoquinone as criterion,it was determined that SnSO4,sodium borate was main cocatalyst.Furthermore,the proper quantity of stannous sulfate added in catalyst was determined to be 1.8 % 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 almost 100%.Basification of catalyst made the selectivity of 1,4-naphthoquinone increase by 15% on average.
