AN IMPROVED METHOD OF SOLIDIFICATION OF PHOSPHORIC ACID BY A MINERAL OR VEGETABLE SUBSTANCE BEING POROUS BODIES
Year: 1885

page_text: I FRANCOIS BARBE of the City of Paris in the Republic of France 15 Rue de
Richelieu, Engineer, do hereby declare the nature of my invention for AN
IMPROVED METHOD OF SOLIDIFICATION OF PHOSPHORIC ACID BY A MINERAL OR
VEGETABLE SUBSTANCE BEING POROUS BODIES to be as follows:-
This invention consists in the preparation of a novel manure, in which hydrated
phosphoric acid, being wholly soluble in water, is solidified by the addition of a
mineral substance, of a porous nature, such for instance as silica or of infusorial
earth which serves for the manufacture of dynamite or an organic substance, such
for instance as saw dust.
This manure is prepared in a very simple manner. The phosphoric acid is
obtained by the ordinary method which consists in decomposing phosphate of lime
by the addition of a somewhat excessive amount of sulphuric acid.
The mixture thus obtained is then suitably lixiviated so as to dissolve the
phosphoric acid, which is then allowed to evaporate until it acquires the consistency
of syrup.
'
The phosphoric acid, while cold is mixed with the porous substance and will
become a valuable manure of which the richness in phosphoric acid will vary
according to the porosity of the mineral or organic matter employed.
The advantages this manure offers to agriculture will be readily understood its
composition is beyond all dispute since, the phosphoric acid it contains is directly
dissolved in water, it being moreover perfectly assimilable.
Again its ingredients are very easily determined I particularly recommend the
manure consisting of a mixture of phosphoric acid and saw-dust, as in this body
the phosphoric element is placed in contact with an organic substance containing
carbon, hydrogen oxygen, as well as a given amount of nitrogen and alkali. Thus
it will be seen that in this manure all the chief elements, capable of promoting
vegetation are contained. The absorbing organic principle may itself, be mixed
with other bodies imparting thereto larger quantities of nitrogen or alkali.

Porous Mineral or Vegetable Bodies for the Manufacture of

I FRANÇOIS BARBE Engineer of 15 Rue Richelieu Paris in the Republic of
France do hereby declare the nature of my invention for AN IMPROVED METHOD OF
SOLIDIFICATION OF PHOSPHORIC ACID BY POROUS MINERAL OR VEGETABLE BODIES
FOR THE MANUFACTURE OF MANURE, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention consists in the preparation of a novel manure in which hydrated
phosphoric acid, being wholly soluble in water is solidified by the addition of a
mineral substance of a porous nature such for instance as silica or of infusorial
earth which serves for the manufacture of dynamite or an organic substance such
for instance as saw-dust.
This manure is prepared in a very simple manner. The phosphoric acid is
obtained by the ordinary method which consists in decomposing phosphate of bone
by the addition of a somewhat excessive amount of sulphuric acid. The mixture
thus obtained is then suitably lixiviated so as to dissolve the phosphoric acid which
is then evaporated until it acquires the consistency of syrup.
The phosphoric acid whilst cold is mixed with the porous substance and will
become a valuable manure of which the richness in phosphoric acid will vary accord-
ing to the porosity of the mineral or organic matter employed. The advantages
this manure offers in agriculture will be readily understood: its composition is
beyond all dispute, since the phosphoric acid it contains is directly dissolved in
water it being moreover perfectly assimilable.
Again its ingredients are very easily determined. I particularly recommend the
manure consisting of a mixture of phosphoric acid and saw-dust as in this body
the phosphoric element is placed in contact with an organic substance containing
carbon, hydrogen, oxygen, as well as a given amount of nitrogen and alkali. Thus
it will be seen that in this manure all the chief elements capable of promoting
vegetation are contained. The absorbing organic principle may itself be mixed
with other bodies imparting thereto larger quantities of nitrogen or alkali.
Having now particularly described and ascertained the nature and particulars
of my said invention and in what manner the same is to be performed I declare
that what I claim is
A novel manure wherein phosphoric acid soluble in water is solidified in com-
bination with or by the addition thereto of porous bodies of either organic or
mineral nature as and for the purpose herein set forth.
