Title: Process for the preparation of titanium oxide and articles based on titanium oxide.
Inventor: CHOPIN THIERRY
IPC: B01J27/135
Filed: 1995-02-28
Abstract: The present invention relates to a process for the manufacture of articles made of titanium oxide. 
<??>This process consists essentially in manufacturing a titanium oxide capable of being shaped, especially by extrusion, by hydrolysing a titanium compound. According to the invention this hydrolysis is conducted in the presence of at least one compound chosen from the group comprising carboxylic acids containing a hydroxyl and/or amine group, and organic phosphoric acids. The titanium oxide thus obtained can be shaped, for example by extrusion, to yield articles exhibiting good porosity and good mechanical properties permitting use in catalysis, for example.
