PROVISIONAL SPECIFICATION,
Improvements in the Manufacture of Saponaceous Products from
Petroleum.
T, CHARLES WEYGANG, of 17, Park Place, Gravesend, in the County of Kent,
Chemist, do hereby declare the nature of this invention to be as follows:-
This invention has for its object certain improvements in or relating to or in
connection with various processes well known in the art for producing miscible
oils but more particularly in that for which Letters Patent have been granted to
me numbered 8025 of 1894 and refers more particularly to the use or combination
with mineral oils of saccharine substances such as sugar, dextrine, or their ana-
logues or equivalents hereinafter all referred to and described as * saccharine
matter."
According to my invention I add saccharine matter so as to mix or combine
with the resultant compound.
For instance 1 make a saturated or strong solution of an alkali, such as caustic
soda, and I dissolve therein saccharine matter to any point up to saturation.
I make a melt of a mineral oil and saponifiable matters, for instance, such as
petroleum and rosin and I gradually add the alkaline solution thereto substan-
tially as described in my said Specifications more particularly that numbered 3025
of 1894, and thus produce a more or less miscible or soluble oil.
In order to render this yet more miscible or soluble I may further add a small
percentage of soap or other fatty matter which is readily saponifiable or soluble
with alkali.
I may also combine further proportions of saccharine matter by mixing the
miscible or soluble oil with water containing such saccharine matter in solution,

My invention comprises the addition of saccharine matter in such manner that
it may mix and combine with the constituents forming the resulting saponaceous
compound.
According to my invention I make a strong or saturated solution of an alkali,
by preference, caustic soda or potash, and I dissolve therein saccharine matter,
employing in most cases, ordinary sugar. I may employ an amount of sugar
which will saturate the solution or any less amount.
I then make a melt, substantially as described in my said earlier specifications,
of a mineral oil and a saponifiable matter, generally petroleum and rosin, and I
introduce the saccharine solution of alkali above described gradually and inter-
mittently substantially in the manner described in the before mentioned speci-
fications with reference to alkaline solutions without saccharine matter.
I thus produce in the first instance a saponaceous mixture, or emulsion, which
is miscible with water and in which the constituents are very thoroughly
combined.
The miscible petroleum oil or mixture thus obtained is useful, among other
purposes, for making siccative oils which form bases for varnishes and vehicles
for paints, and for this purpose I find that the best results are obtained by treat
ing the lighter distillates of mineral oils in the above way and I have obtained
excellent results by using oils having a sp. gr. of between 475 and 820.
In order to produce such siccative oils the miscible oil or emulsion obtained
--as-described-above is treated-with-a-mineral-salt--which-will-neutralize-the-alkali
and impart siccative properties to the resulting product.
Good results are produced by using calcium chloride, calcium sulphate, mag-
nesium sulphate, or salts of the metals, of which I prefer to use sulphate of zinc
_and_the_process_in_this_respect-is-substantially_the_same_as_that_described_in_the_
Specifications No. 3025 and 23995, both of 1894.
If the miscible oil or emulsion is required to be of a more soluble character
as would be necessary for purposes requiring dilution with much water, such as
for the manufacture of soap, insecticides, sheep-dips, disinfecting and cleansing
fluids, and other similar purposes, I add to the miscible oil or emulsion a small
percentage of a good pure soap, or a fatty matter which is readily saponifiable
or soluble with alkali, substantially as described in the herein before mentioned
specifications. It being understood that the proportions of such soap or fatty
matter may vary from 5 to 50 per cent. and more, according to the result the
operator desires to achieve.
At this stage it is generally advantageous to introduce in a gradual manner
a little more water, preferably softened with a small quantity of alkali; and fur-
ther proportions of saccharine matter may be combined with this water.
The proportions of the saccharine matter in the alkaline solution may vary
considerably, as also may the strength of the alkaline solution, and the following
proportions are given as having been found to be good useful working propor-
tions, without in any way indicating the limits within which the proportions
may be varied.
One to three parts by weight of sugar. Eight parts by weight of a solution of a
caustic soda of 35° B. The larger proportion of sugar being the most useful pro-
portion for most purposes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I claim
is: --
.
(1) In the formation of a miscible oil or sauneus mixture from minoval

page_text: oils the use of saccharine matter in combination with an alkali substantially as
described.
(2) A miscible saponaceous product from mineral oils produced by the gradual
action of alkali in combination with saccharine matter substantially as
described.
(3) A more or less soluble product from mineral oils, produced by the gradual
action of alkali in combination with saccharine substances substantially as
described.
(4) In the production of a siccative oil from mineral oil, the employment of
a mixture of an alkali and saccharine substances substantially as and for the pur-
pose hereinbefore described.
(5) The process for producing a miscible solution of mineral oils herein before
described and for the purposes set forth.
