Abstract
The present invention provides a method for the Industrial production of a titanium salt TP, said method comprising the steps of: i. Precipitation of titanic acid from a solution comprising titanium salt TP1; ii. Production of a titanium containing product TP2 from a medium comprising of said titanic acid and an acid; and iii. Thermal conversion of titanium containing product TP3 to a titanium salt TP at temperature higher than 170° C.
Claims31
A method for the industrial production of a titanium salt TP comprising:
- (i) precipitating titanic acid from a solution comprising titanium salt TP1,
- (ii) producing a titanium containing product TP2 from a medium comprising of said titanic acid obtained from step (i) and an acid;
- (iii) converting said titanium containing product TP2 obtained from step (ii) to a titanium containing product TP3 by a method selected from the group consisting of dehydration, acidulation, reduction and combinations thereof;
- and
- (iv) thermally converting said titanium containing product TP3 obtained from step (iii) to a titanium salt TP at temperature higher than 170° C.,
- wherein,
- TP3 is a mixture of at least two titanium salts selected from the group consisting of TiOX2, TiOX, TiX3, TiX2 and a combination thereof;
- wherein X is a halide.
