- the preparation of the compound of the invention will now be described.
- the method comprises a first step in which a mixture is formed comprising a salt, a sol or a suspension of titanium, a compound of element M and a compound of cerium.
- Titanium is generally used in the form of a compound of this element.
- This compound can be a salt.
- This titanium salt is generally chosen from halides, oxyhalides, sulfates, oxysulfates and titanium alkoxides. More particularly, titanium can be used in the form of titanium dioxide in suspension or in the form of a sol.
- Said gel can be obtained by neutralizing a solution of a titanium salt with a base.
- This titanium salt is generally chosen from the salts mentioned above. More particularly, a titanium halide or oxyhalide will be used, preferably titanium oxychloride.
- a titanium halide or oxyhalide will be used, preferably titanium oxychloride.
- titanium dioxide sol can be obtained by thermohydrolysis of a solution of a titanium salt, possibly in the presence of germs of titanium dioxide or one of its hydrates (thermohydrolysis seeded).
- This titanium salt can also be chosen from halides, oxyhalides, sulfates, oxysulfates and titanium alkoxides.
- titanyl sulfate will be used.
- the soil can also be obtained by following the process described in EP-A-335773, the teaching of which is incorporated here.
- This process consists in resuspending in an aqueous liquid medium a titanium dioxide which has been obtained by hydrolysis of a titanium oxychloride in the presence of an acid or a salt of an acid of the citric acid, gluconic acid type. , tartaric acid, aspartic acid.
- the above-mentioned aqueous liquid medium can be acidic or basic.
- the cerium can be present in the compound in the form III + and or IV + , the cerium can be provided in the form of a compound of cerium III + and / or of a compound of cerium IV + .
- the element M and the cerium are generally brought in the form of a salt.
- Water-soluble salts are preferably used.
- Inorganic salts or organic salts can be used.
- inorganic salts there may be mentioned more particularly nitrates.
- cerium it can be used for example in the form of cerium nitrate III + and / or cerium nitrate IV + .
- An aqueous solution of ceric nitrate can for example be obtained by reaction of nitric acid with a hydrated ceric oxide prepared in a conventional manner by reaction of a solution of a cerous salt, for example cerous nitrate, and an ammonia solution in the presence of hydrogen peroxide.
- a ceric nitrate solution obtained according to the electrolytic oxidation process of a cerous nitrate solution as described in document FR-A-2 570 087, and which can constitute an advantageous raw material.
- the aqueous solution of cerium IV salts may have a certain initial free acidity, for example a normality varying between 0.1 and 4 N.
- an initial solution of cerium IV salts actually showing some free acidity as mentioned above, that a solution which will have been previously neutralized in a more or less extensive manner by adding a base, such as for example an ammonia solution or also alkali hydroxides (sodium, potassium, etc. .), but preferably an ammonia solution, so as to limit this acidity.
- a neutralization rate (r) of the initial cerium solution by the following equation:
- ni represents the total number of moles of Ce IV present in the solution after neutralization
- n2 represents the number of moles of OH ions "effectively necessary to neutralize the initial free acidity provided by the aqueous solution of cerium salt IV
- n3 represents the total number of moles of OH ions" provided by the addition of the base.
- organic salts of element M and of cerium As organic salts of element M and of cerium, oxalates and acetates can be mentioned.
- Titanium, element M and cerium are mixed in the proportions corresponding to the stoichiometry of the desired compound.
- the above-mentioned mixing can be carried out by first bringing together the titanium salt, sol or suspension and a compound of element M, then, secondly, by adding to the first mixture thus obtained a compound of cerium. In a second stage of the process, the mixture obtained above is dried.
- the drying is carried out by atomization.
- spray drying is meant spray drying of the mixture in a hot atmosphere (spray-drying).
- the atomization can be carried out by means of any sprayer known per se, for example by a spray nozzle of the sprinkler apple type or the like.
- spraying techniques likely to be used in the present process, reference may be made in particular to the basic work by MASTERS entitled "SPRAY-DRYING" (second edition, 1976, Editions George Godwin - London).
- the gas inlet temperature can be for example between 200 and 220 ° C.
- the gas outlet temperature can be between
- the treating gases are driven in a helical movement and flow in a vortex well.
- the mixture to be dried is injected along a trajectory coincident with the axis of symmetry of the helical trajectories of said gases, which allows the momentum of the gases to be transferred perfectly to the mixture to be treated.
