室温和低酸度条件下钨酸的制备

Preparation of Tungstic Acid at Room Temperature and Low Acidity

本文提出了一种在室温(~20℃)和低酸度(~1/V)条件下制备钨酸的新方法,讨论了钨酸的生成机理、化学组成和物理性能。

A new method is described for the preparation of tungstic acid at room temperature(~20℃)and low acidily(~1N)with a high yield(~99%)so it possesses industrial meaning.This method uses H_(2)O_(2),as a coordination agent,treact with tungstate forming peroxotungstatc which then is decomposed.Physical proporties of the tungstic acid were studied.
