摘要： 在盐酸介质中,TiCl4水解行为的研究对盐酸法制取钛白[1]的工艺过程是极其重要的,而这方面的一些基础理论研究,至今尚不多见。为此,我们对在盐酸介质中,在二价铁盐存在下的TiCl4水解动力学行为进行了研究,取得了一些结果。

Abstract: The kinetic behavior of hydrolysis of TiCl4 in the solution of hydrochloric acid of ilmenite was studied; the relation between the degree of hydrolysis and concentration of Ti(Ⅳ), temperature of hydrolysis, quantity of seed added and acidic concentration have been found and the following relation dn/dt = 0.lC-1:5· ·n0.6 (at η = 25%) was discovered, where Cis the initial concentration of Ti(Ⅳ), n the quantity of seed added.The calculated value of action energy which was obtained from the relation of temperature and the degree of hydrolysis was 201.9kJmol-1.
