Equipment of preparation of 1,4-naphthoquinone is scaled up and catalyst is tested with it,the result shows that larger catalyst particles and changing its surface alkalescence can make the selectivity of 1,4-naphthoquinone increases by 15% on average,moreover,the catalyst＇s performance could be improved by change its configuration and perpare porcelain ring catalyst,so it can reduce the effect of scaling-up equipment.
