FRIEDRICH POSPIECH,
PATENT OFFICE OF D'RESDEN, GERMANY, ASSIGNOR TO OHEMISCHE FABRIK POTT & 00., OF DRESDEN, GERMANY rnocnss FOR PRODUCING sonvnn'rs AND EMuLsIFYIive Aenn'rs no Drawing. Application filed August 26, 1927, Serial No. 215,764,;nd in Germany February 25, 1926.
Numerous processes have. already been proposed for the production of solvents and emulsifying agents for liquid and solid substances which are themselves insoluble in Water, such as for instance oils, fats, mineral oils, hydrocarbons, waxes and the like.
In addition to the means such as soap and Turkey red oil T which have been used for some time, cyciohexanol or its homologues by themselves'or in combination with hydro: carbons has been converted for instance for this purpose into a form soluble in water by means of soaps. v
It has been found, that particularly good results are obtained, if aromatic or aliphatic alcohols, which are diflicultly soluble or 111-.
soluble in water, are treated, either by themselves or in combination with hydrocarbons, with the alkali salts of aromatic. or hydroaromatic hydrocarbon sulfonic acids or their derivatives as well as also with the corresponding free acids.
Benzyl alcohol and mixtures of benzyl alcohol with ordinary or chlorinated solvent naphtha have proved particularly suitable for the purpose in view.
Benzyl alcohol has a distinctive character as compared with the alcohols of high molecular weight. which are insoluble in water, such as cyclohexanol amyl alcohol terpene alcohols, since it possesses particular technical advantages, which make it "especially suitable for the purpose in question.
The surprising discovery has been made, that it does not affect the frothing capacity of the preparations obtained. It is this fact in particular, which is of pro-eminent importance for cleansing and emulsifying agents; In addition however, benzyl alcohol has the advantage, that it has only a. very slight odor. This fact is also important, because it is particularly desired in the industry to employ products which are as far 1 as possible odorless. as it is difficult to eliminate such odors from the treated textile materials, and inconveniences are thus caused to those dealing therewith.
In this manner productsare obtained,
h which can be used very effectively as solvents and emulsifying agents for fats of all kinds,
Ewamples 1. 15 parts of butyl naphthalene sulphonic acid are dissolved in parts of water, and 28 parts of solvent naphtha are added thereto. The resulting emulsion is converted by means of 8 parts'of normal butyl alcohol into a clear solution,which when mixed with or poured into a considerable amount of water yields finely dispersedv emulsions of the solvent.
2. 25 parts of the sodium salt of isopropylnaphthalene sulphonic acid are dissolved in through several non-homogeneous intermediary stages, a clear'homogeneous liquid is finally obtained, WhlCll when diluted with a considerable amount of water, yields clear solutions of benzyl alcohol, which are not even opalescent. As is well known benzyl alcohol dissolvesvery sparingly in water.

sodium salt of isopropyl-naphthalene sulfonic acid in the proportion of about 14 parts of benzyl alcohol to 25 parts of the sodium salt.
