Ticl4 hydrolysis
Webb6 juli 2007 · Hydrolysis of TTIP offered a turbid solution which heated up to 60–70 °C for almost 18–20 h (peptization). After peptization process, the volume of the solution decreases to 50 cm 3 and a suspension was produced. Depending on the preparation conditions, the resultant suspension was white-blue or opaque with high viscosity. Webb通过从四氯化钛混合液水解前后主要成分的变化情况、四氯化钛水解反应机理、水解过程控制等方面对TiCl4精制工序的预水解和蒸馏釜底残液水解技术应用进行了分析，确定了TiCl4水解的加水量、加水方式和水解后混合液沉降时间是TiCl4水解工艺过程的关键控制点，并与传统处理工艺进行了比较。
