I HANS RITTER VON DAHMEN of IV Belvedere Gasse No. 3 Vienna, Austria
Chemist do hereby declare the nature of this invention to be as follows:-
My invention has for its object to convert hydrocarbons, such as the heavy
minerals oils, into an oleaginous material which is capable of being converted into.
soaps by any known saponifying process, so as to produce a cheap article of commerce,
and which may also be used with advantage for other purposes such as for dressing.
wool preparatory to the carding and spinning processes.
For this purpose 1 mix in the first instance. with the said hydrocarbons Elain or
Oleic Acid in proportions that may be varied considerably, such as from 10 to 25 per
cent. of the hydrocarbons, and I then subject this mixture to the action of a gas such
as sulphuretted bydrogen whereby a chemical reaction is effected which enables the
compound to be readily acted upon by alkalies for its conversion into saponaceous
material in any known manner.
It is preferable that the compound should be heated to some extent while under the
action of the gas, which may be allowed to act upon it for about an hour.

COMPLETE SPECIFICATION.
An Improved Manufacture of Oleaginous Material from Hydro-
carbons, Applicable for Saponification and other Purposes.
I, HANS RITTER VON DAHMEN of IV Belvedere Gasse No. 3 Vienna, Austria,
Chemist, do hereby declare the nature of this invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the following
statement:-
My invention has for its object to convert hydrocarbons such as the heavy mineral
oils into an oleaginous material which is capable of being converted into soaps by any
known saponifying process, so as to produce a cheap article of commerce, and which
may also be used with advantage for other purposes such as for dressing wool
preparatory to the carding and spinning processes.
For this purpose I mix in the first instance with the said hydrocarbons Elain or
Oleic Acid or fatty acid in proportions that may be varied considerably such as from
10 to 25 per cent of the hydrocarbons, and I then subject this mixture to the action of
a gas such as sulphuretted hydrogen or gas having similar properties whereby a
chemical reaction is effected which enables the compound to be readily acted upon by
alkalies for its conversion into saponaceous material in any known manner.
It is preferable that the compound should be heated to some extent while under the
action of the gas which may be allowed to act upon it for about an hour.
The introduction of sulphuretted hydrogen gas in the oleaginous mixture has for its
object the uniform distribution of the oxygen throughout the mass.
In practically carrying out the manufacture of this compound, I mix from 5 to 15
per cent. or more of a fatty acid with the mineral oil under heating to about 60 °C., and
into this mixture I introduce sulphuretted hydrogen gas in such quantity that the oil
is completely saturated therewith.
The mixture is then neutralized by the addition of from 1 to 5 per cent. calcined
carbonate of soda, and the product is then mixed with any other saponifiable fat and
boiled in the usual manner.

page_text: The reaction resulting from the use of sulphuretted hydrogen is as follows:
Sulphuretted hydrogen, as is well known, is a very powerful reducing agent and
possesses the property of taking up oxygen from soft bodies containing the same as
also from the atinosphere, and, after decomposition to impart the same to bodies, poor.
in oxygen brought in contact therewith. The gas consequently in the present instance'
takes up oxygen from the air as also from the fatty acid, and imparts the same
uniformly to the mixture of mineral oil and fatty acid, whereby a certain degree of
saponification will be effected even with only a small percentage of oxygen, that is to
say, the mixture forms in combination with caustic lye an emulsion of such consistency
that, after well boiling, no oil will separate therefrom again.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is a
:-
1. The process for the production of an oleaginous material capable of being readily
converted into saponaceous matter by means of alkalies, consisting in the admixture
with hydrocarbons, such as the heavy mineral oils, of elain or oleic acid, or fatty acids,
and the subsequent treatment of this mixture with sulphuretted hydrogen, or other
gas having similar properties, substantially as herein described.
2. An oleaginous compound consisting of a hydrocarbon such as the heavy mineral
oils, mixed with clain or oleic acid or fatty acid and treated with sulphuretted hydrogen
or other gas having similar properties, substantially as herein described.
3. A saponaceous material consisting of the oleaginous compound referred to in the
preceding claims, treated with alkalies, substantially as herein described.
