Organic Substances.
We, CARL SCHILL and CHRISTOPH SEILACHER of Stuttgart, in the Empire of
Germany, Manufacturers, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the oxidation of train-oil and of other fats and oils.
Train-oil or other grease when exposed for a large surface, to the atmospheric air,
the oxygen of the latter oxidizes the constituents of the material. In this process, in
case of train-oil, the phonicine is first destroyed and the unpleasant smell thereby
removed. The glycerides are also converted into glyceride-acids and during the
further course of oxidation split up into glycerine and fatty acids.
The mixture of these products of oxidation is capable of forming an emulsion
with water.
In our improved process we disperse the heated grease or oil in the form of spray
in suitable chambers by means of a blast of hot air and cause it to recondense. For
this purpose the train oil is pressed into a reservoir, where it is heated to about
120° Centigrade. From this receptacle the grease flows through a pipe to a suitable
injection-apparatus 4, to which is also connected an air pipe from a receptacle in
which heated air is compressed to 4 or 5 atmospheres. The grease is injected thereby
into a suitable chamber so that it is dispersed as finely as possible. A part of this
grease spray is precipitated in the chamber and gives a refined train-oil, but the
greater part passes as a fine mist through a series of condensing chambers in which
are arranged a series of deflecting plates or other means for causing the vapour to
take a very lengthened and circuitous course.

page_text: As the capacity for oxidation of different oils and fats is not the same, ozonized or
superoxidized air or air mixed with ammonia may be employed if necessary for
dispersing the material, or the greases may be mixed with any oxidizing salts.
The refined oil may be used in the manufacture of leather, of soap, and also in
dyeing as a substitute for tournante-oil.
This process is also applicable to the oxidation of other organic bodies, since the
effect is capable of being considerably increased by ozonizing the oxygen or by use of
a mixture of air with ammonia.

increased by ozonising the oxygen or by the use of a mixture of air and ammonia.

page_text: Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that what we claim is
(1) A process for the oxidation of train-oil and other oils and fats consisting in
dispersing the same in the form of spray together with and by means of hot compressed
air into a suitable chamber or chambers and condensing it therein substantially as
described.
2) The method of oxidizing organic substances by dispersing the same in the form
of spray into suitable chambers by means of and together with hot compressed.air, or
ozonised air, or a mixture of air and ammonia, and recondensing the products.
