| Abstract: | The reaction mechanism of kaolin and hydrochloric acid is connected by many reaction steps in series. In this paper,effects of the amount and concentration of hydrochloric acid,stirrer speed,particle size and reaction temperature on the rate of soaking out of Al 2O 3 are investigated.Operating area of each controlling step in the reaction process is determined.From these,a series of research work such as reaction model,chemical kinetics of the reaction can be carried out. |
