摘要： The invention relates to a process carried out continuously in one or more reactors connected in series for the preparation of sodium titanate nanotubes and their derivatives obtained by ion exchange and/or thermal treatment, by reacting titanium oxides with sodium hydroxide under suitable hydrothermal conditions to obtain or control the morphology of nanostructural titanates. The reaction mixture is introduced continuously into the reactor at a feed rate that is the same as the rate of discharge of the product. When more than one reactor is used, the material leaving the first reactor is used to feed the next reactor, and a differential of temperature is applied between the reactors in such a way as to obtain in the average, a temperature of between 60° C. and 180° C.

摘要： Process for the preparation of quasi-crystalline boehmite comprising the steps of: (a) preparing an aqueous precursor mixture comprising a water-insoluble aluminum source; (b) decreasing the pH of the precursor mixture of step (a) by at least 2 units; (c) increasing the pH of the mixture of step (b) by at least 2 units, and (d) aging the mixture of step (c) under hydrothermal conditions to form a quasi-crystalline boehmite. This process provides for the hydrothermal preparation of quasi-crystalline boehmites with high peptizability. The invention therefore further relates to quasi-crystalline boehmites with a high peptizability, measured as the Z-average submicron particle size. This Z-average submicron particle size preferably is less than 500 nm, more preferably less than 300 nm, even more preferably less than 200 nm, and most preferably less than 100 nm.
