摘　　要：本文用乙醚酸化萃取法合成产物,用红外、紫外光谱对产物进行表征,确定为目标产物,利用静态挂片失重法对目标产物的缓蚀性能进行分析与研究,结果显示40℃条件下,不同结构比例磷钨钒杂多酸在p H为8.1时3.5%氯化钠溶液中,Dawson型H9[P2W15V3O62]杂多酸缓蚀性能最好。The ethyl ether acidification is used to synthesize the target products,which is determined by IR and UV. The inhibitive corrosion performance of the target product is examined and compared by the static hanging piece and weight loss method. The results show that under the condition as 40℃,PH 8. 1,with content 1200 mg/L,and preserved in the sodium chloride solution,for heteropoly,the inhibitive corrosion performance of Dawson type H9[P2 W15 V3 O62]is the best.
