Titanium (III) phosphide is an inorganic chemical compound from the group of phosphides .

Extraction and presentation

Titanium (III) phosphide can be obtained from the elements by pressure synthesis.

{\ displaystyle \ mathrm {Ti + P \ longrightarrow TiP}}

It can also be obtained by reacting monophosphane with titanium (IV) chloride at 750 ° C. Likewise possible is the electrolytic preparation of a nearly stoichiometrically composed titanium (III) phosphide powder at 860 ° C from a solution of 10% titanium dioxide in a mixed melt which, in addition to di- and metaphosphate, also contains sodium chloride and lithium fluoride .

Finely powdered titanium hydride can be converted into phosphides with lower phosphorus contents at 800-1000 ° C with a monophosphine / hydrogen mixture (TiP _0.1-0.6 ).

properties

Titan (III) phosphide is a black-gray, metallic-looking and thermally very stable powder that is not very vulnerable to acids, even when heated. It has a hexagonal crystal structure with the space group P 6 ₃ / mmc (space group no. 194) (a = 3.487 Å , c = 11.65 Å). Template: room group / 194

use

Titanium (III) phosphide is used as a catalyst in organic syntheses.
