PROVISIONAL SPECIFICATION.
A Method of Manufacturing and Regenerating Salts of Peroxide
of Iron.
I, ANDRÉ EUGENE MARIE LUCIEN PAILLARD, of 31 Boulevard Henri IV,
Paris, in the Republic of France, Engineer, do hereby declare the nature of my
invention to be as follows:-
The object of this invention is to provide a method of manufacturing and
regenerating salts of peroxide of iron so that the useful known oxydising qualities
of these salts may be economically employed in such manufactures and industries
where these qualities are applicable.
This invention consists in providing a method which by the use of certain
appropriate apparatus may convert the respective suboxide salt into the peroxide
by the addition of the necessary acid for constitution of the respective peroxide
salt and nitric acid to effect the peroxidation.
The salt of protoxide of iron to be treated and the necessary amount of acid to
complete the constitution of the relative peroxide salt together with a little nitric
acid are blown through or by a steam jet or injector leading into a reservoir where
the vapours and gases are separated from the liquid, the latter being drawn.off by
a syphon and the former returned to an absorber or absorbing chamber connected
with the suction pipe of the injector and provided with orifices with means for
regulating the mixture of air and of the liquid in suitable proportions. The nitric
acid regenerates itself in this apparatus to a certain extent so that only a small
quantity of this acid is added, the presence of nitrous acid in the peroxide salt will
not render it unsuitable for use.
Inasmuch as salts of peroxide of iron and nitric acid convert sulphurous acid into
sulphuric acid sulphurous acid may often be employed with economy in place of
sulphuric acid in this process for the production of persulphate of iron.
The peroxide salts being by their employment for oxydising purposes converted
into protoxide salts may be regenerated from the latter by the same process.
