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.
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.
