To all wlwm it may comm-n;

Be it known that I, Isaac VANDEN Bronx, a citizen of the United States, (residence and post-oflioe address, 51 East Twentyfifth street, Manhattan, New York city, New York,) have invented certain new'and useful Im rovements in the Art of Making Hydrocar on Soaps, of which the following is a specification.

There have heretofore been known and in some forms commercially used soaps containin volatile hydro-carbon oils such as na ht a.

he object of the present invention is to make in a simple and economical manner a better soap of this character and one which shall better retain than heretofore the hydrocarbon oil notwithstanding. its volatile nature.

To these ends I manufacture 'my soap as follows: I procure commercial potash lye, tallow, cocoanut oil or the equivalent, and a comparatively small quantity of pure soap free from acids, such as good castile soap, or in lieu of this last I may make such pure referred form of my invention proceed as ollows: I take say one hundred grams of the pure soap and dissolve it in one kilogram of water, preferably at a temperature of abou 120 Fahrenheit maintaining this tempera are thro bout the rocess. Ithen mix with this so ution w e stirring, ten grams of ammonia of, say, ninety six per cent. s ecific gravity, andinto this I stir gradua y a small constant stream" of kerosene and naphtha in equal parts, or of kere sene and naphtha mixed, as aforesaid, preferably using a hollow stirrer through-which the stream may be introduced until I have incorporated about one hundred kilograms.

The hydrocarbon is preferably passedthrough a heated coil so it reaches a temperature of about 120 before passing into the soap emulsion. For convenience I will call this my hydrocarbon emulsion. I also take, say, thirty kilograms of the tallow and thirty kilograms of the cocoanut oil and melt the same by heat. I introduce in a stream thirty kilograms of potash lye 36 Baum, maintaining ,the heat referably between 120 and 140. To the a ali soa so formed I now add about ten kilograms o the hydrocarbon emulsion, using a hollow stirrer and suificient head or pressure so as to conduct the emulsion down into the mass and stir it a sp ifi ti n or mm m Patented May 31, 1910.

into it adually, allowing the mass to cool. Prefer-filly I employ cooling coils so as to reduce the temperature rapidly and check the evaporation of the hydrocarbon. As the mass cools it breaks up into a lumpy solid mass which is then thereafter preferably ground or further broken up into grannlated form. In this granulated form I box it and ship it. The product so obtained forms excellent and pure hydrocarbon soap of detergent quality and without the presence of adulterants such as are commonly present in the cheaper grades of soaps,

now on the market. The volatile hydrocarbon is incorporated-and held in a manner which, so far as I am aware, is peculiar to this process. I am not able to statewhetber the action of the ammonia is a purely chem ical action upon the soap or a .catalytic action in the process, the relativelysifiall quantity used in proportion to the other bodies present indicating to me the possi bility of the latter.

As it is conceivable that this product may be made by other processes,I claim the productas an article of manufacture, in my copending application-No. 377,507, filed herewith, separately from the process by which it formed, the present application being for the particular process.

What I claim and desire to secure by these Letters Patent is 1. The improvement in the art of making hydrocarbon soaps, which consists in first emulsifying the hydrocarbon with soap and the aid of a relatively minute quantity of ammonia and then gradually stirring it into a heated'mass of' soap and cooling the same.

2. The improvement in the art of making hydrocarbon soaps, which consists in first emulsifying the hydrocarbon with a dilute solution of soap containing a small quantity of ammonia and then gradually stirring it into a heated mass of soap and cooling the siameaand then granulating the-mass so prouce 3. The improvement in the artof making.

step 0 hydrocarbon soaps, comprising the drocarbon into a solution of soa containing approximatel ten parts by weight of soap to one part 0 ammonia water at a temperature a proximating one hundred and twenty egrees Fahrenheit.

5. The improvement in the art of making hydrocarbon soaps, comprising the step of emulsifying a volatile hydrocarbon consisting largely of naphtha by stirring the hydrocarbon into a solution of soap containing approximately ten parts by weight of soap to one part of ammonia water at a temperature approximating one hundred and twenty degrees Fahrenheit and continuing the addition of hydrocarbon until at least one hundred parts thereof for each part of soap are present.

6. The improvement in the art of making hydrocarbon soaps, comprising the step of emulsifying a volatile hydrocarbon consisting largely of naphtha by stirring the hydrocarbon into a solution of soap containing approximatel ten parts by weight of soap to one part 0 ammonia water at a temperature approximating one hundred and twenty degrees Fahrenheit and the subsequent step of stirring and mixing such emulsion gradually into a mass of soap in the liquid state and to an extent not exceeding fifteen percentum of the emulsion relatively to the mass of soap by weight.

7. The improvement in the art of making hydrocarbon soa s, comprising the step of making an emulsion of volatile hydrocarbon with an aqueous solution of approximately ten parts by weight of soap to one hundred parts by weight of water to which has been added approximately one part of ammonia water.

8. The improvement in the art of making hydrocarbon soaps, comprising the step of emulsifying volatile hydrocarbon, consisting largely of naphtha by stirring it into an aqueous soap solution in a substantially neutral or but very slightly alkaline condition and at a temperature of approximately Ione hundred and twenty degrees Fahreneit.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
