Serial No. 414,226. 1929 2 Claims.

The present invention has for an object to provide an improved detergent and an improved process of producing the detergent. In applicants co-pending application for Letters Patent, Serial No. 414,225, filed December 14, 1929, there is described a wetting-out, washing, cleaning and emulsive compound characterized by a combination of alkaline phosphates and sulphonates of organic bodies. As set forth in said application, it has been found that surprising advantages are obtained by combining the alkaline phosphates and the sulphonates of organic bodies and that results havebeen obtained that would not reasonably be expected from the effect of either the phosphates or the sulphonates, when used separately. It has been discovered, in accordance with the present invention, that mixtures of alkaline phosphates and sulphonates of organic bodies provide even better effects because of their wetting-out and emulsifying properties with the results of better washing and cleaning properties, if they are combined on an equal basis with higher molecular alcohols. It is a matter of practical importance that the new mixtures, that is the phosphates together with I the sulphonates and alcohols be heated for some time and raised to a higher temperature, since hereby those chemical processes evidently only take place in the fullest measure which play such a decisive role in bringing about the above mentioned efiects;

If for instance, we prepare a mixture of parts by weight of terpineol and 35 parts of an 80% Turkey-red oil and add to this mixture 50 parts of tri-sodium phosphate we will get after a short time of heating of this mixture a saline product, which is solid when cold, yielding a completely clear solution in water and also possessing a wetting-out power even in very dilute solutions and, as far as the best known wetting-out preparations as met with in the trade are concerned, second to none. The temperature should be such as to provide complete fluidity and should be con- In Germany October 24,

to play others, higher molecular alcohols as for instance butyl alcohol, amyl alcohol, cyclohexanols-or mixtures of higher molecular alcohols and related hydro-carbons and it is up to the technical expert to find and select in each individual case the ingredients best suited for the purposes intended. At all events, the preparations if compounded according to the directions as mentioned may be used in numerous technical instances and may either be applied, always dependent upon their compounded form, in cases of delicate manipulations, as for instance in the textile industry, or on the strength of their low cost of production for the roughest technical purposes as for instance in the production of asphalt or tar emulsions, for street cleaning purposes etc.

.I claim:-

1. A detergent comprising an alcohol of the group consisting of butyl alcohol, amyl alcohol, terpineol and cyclohexanol, material of the group consisting of sulfonic acids and their alkali metal salts, and tri-sodium phosphate the ingredients being combined in a proportion of the order of 15 parts, 35 parts and 50 parts. I

2. The process of producing a detergent which comprises melting together approximately 15 parts of an alcohol of the group consisting of butyl alcohol, amyl alcohol, terpineol and cyclohexanol, 35 parts of Turkey red oil and 50 parts of tri-sodium phosphate.
