EMILE ANDREOLI, Journalist, of 18 Somerleyton Road, Brixton S.W. London do
hereby declare the nature of this invention to be as follows
-
The object of this invention is the utilization of ozone for thickening drying oils
and rendering them useful for the paints, varnishes, and spent oils, etc, or for trans-
forming them into thick semi-solid elastic products for the manufacture of oil cloth,
linoleum, lithographic and printing inks, etc
The treatment of oils consists in making them absorb electio-static ozone instead
of submitting them as usually to the oxidation by the air or by the oxidation
produced by the action of certain chemical reagents, such as the metallic oxides,
acetatos, borates, oxalates, oleates or soaps or certain metals in the divided state.
This ozone, in the state of ozonised an or ozonised oxygen is produced as indicited
in my English Patents 17426", 9631", 21794"
When I use oxygen which I ozonise and which I pass through the oil in convenient.
apparatuses, I can recover it partly after the operation in the state of oxygen which
can again he ozomised for further oxidations of oils
This treatment of oils by means of ozone can be applied without distinction to any
system of ordinary oxidation by bubbling of air through the oil or the passage of hot
air over layers of oil, or pulverization of oil in a current of hot air. I can substitute
it for or combine it with metallic oleates or other chemical reagents but in such a
case the quantities of diyers are greatly diminished and it is never necessary to boil
the oils for hours, on the contrary, a gentle heat is sufficient The ozonisation is
preferably pieceded by purification of the oils to precipitate the albuminous,
mucilaginous matters and other similar agents which form round the molecules a kind
of insulating film which stops the oxidation. I may hasten the superoxidation of the

of hydrocarbons or other substances possessing great affinity for oxygen and

Treatment of Drying Oils.
EMILD ANDREOLI, Journalist of 18 Somerleyton Road Brixton S.W London do
hereby declare the nature of this invention and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement.-
The object of this invention is the utilization of ozone for thickening drying oils
and rendering them uselul for the paints, varnishes, and speut oils, etc., or for trans-
forming them into thick semi-solid elastic products for the manufacture of oil cloth,
linolenin, lithographic and printing inks, etc
The treatment of oils consists in making them absorb electrostatic ozone instead of
being as usually submitted to the oxidation by the air or by the oxidation produced
by the action of by certain chemical re-agents, such as metallic oxides, acetates,
borates, oxalates, olente or soaps or certain metals in the divided state.
This ozone, in the state of ozonised air oi ozonised oxygen is produced as indicated
in my English Patents 174261, 9631", 21794 and 21707.
When I use oxygen which I ozomise and which I pass through the oil in closed
apparatuses, I can recover it partly in the state of oxygen which can again be utilised
for further ozonisations
This treatment of oils by means of ozone can be applied without distinction to any
system of ordinary oxidation by bubbling of air through the oil by the passage of hot air
over the layers of oil, or by pulverization of oil in a current of hot air I can substitute
it for, or combine it with metallic olentes or other chemical re-agents, but in such a
case the quantities of dryers are greatly diminished, and it is never necessary to boil
the oils for hours, on the contrary, a gentle heat is sufficient The ozonisation is
always preceded by purification of the oils to precipitate the albuminous, mucila-
ginous, et, matters by means of tannin and other similar agents as such matters form
round the molecules of the oil a hind of insulating film which stops the oxidation.
Ihasten the super oxidation of the oils, their drying power and their transformation
into solid products by the addition of hydrocarbons tho boiling point of which is over
100° C the proportion of 0.25 per cent in weight, or other substances such as
tallow possessing great affinity for oxygen and consequently for ozone which they
absorb, storo and yield to the oil, rendered more fluid and more divided by agitation.
The purification of oil takes place by adding and mixing to the oil a quantity of
tannin iopresenting about 002% in weight.
After a sufficient rest the oil is ready for treatment.
The bleaching and transparence of the oils treated in this manner are the natural
consequences of the oxidation.
I can also pass layers of oil over a series of large glass plates stacked between
pointed grids such as are used in the construction of my ozomisers, as described in my
Patents No. 17426, 13th October 1891, No 9631, May 20th 1892
As soon as the current passes, the oil submitted to the effluvia is strongly ozonised.
By passing several times at a moderate speed over the glass sheets which are slightly
inclined, the oil at the end of this direct treatment is converted into a solidified whito
layer except at the spots opposite points where is left a slight hollow or crater. The
solidified oil is then collected by scraping or otherwise.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim 15.-
In the treatment of oils which I thicken and solidify by superoxidation in the
apparatuses which are usually employed for the oxidation of oils, the use of electro-
static ozone, either alone or in combination with dryers or with hydrocarbons or
substances having great affinity for ozone.
