- the compounds of the present invention have th-e general structure shown in FIG. 1;
- R divalent hydrocarbon or substituted hydrocarbon radical, as described below land exemplified in FIG. 2.
- X a metal, or hydrogen or quaternary ammonium (which, for the purposes of this invention, acts like a metal) or a 'combination thereof.
- Particularly preferred are hydrogen, quaternary ammonium and metals selected from the following groups of the Periodic Table; Ia, Ib, Ha, IIb, IIIa, IIIb, IVa, IVb, Va, Vb, Vla; including such meals as Li, Na, K, Rb, Cs, Ca, Ag, Au, Be, Mg, Ca, Sr, Ba, Ra, Zn, Cd, Hg, B, Al, Sc, Y, La, land the other rare earths, Ac, Ga, In, T1, Ti, Zr, Hf, Ge, Sn, Pb, V, Nb, Ta, Sb, Bi, Cr, Mo, W, Mn, Fe, Ru, Co, Ni, Rh, Pd, Os, and Ir.

- R may be hydrogen, lower alkyl (e.g., ethyl, hexyl) or aryl (e.g. monovalent radicals corresponding to the aryl radicals described in FIG. 2.
- R shown in FIG. 2 are set forth for purposes of elucidation, not restriction.
- the values of m and n described above are on the basis of the integers which will be used to describe a single molecule.
- the invention will involve mixtures of molecules of the general form described above.

- the value of a may be from about 0 to 2000, more preferably from to 400, and most preferably from 2 to 200.
- the present invention relates to a new class of emulsifying agents, their preparation, and processes for their use.
- the compounds of the present invention may be added to immiscible mixtures of water and organic compounds, e.g., equal parts by volume of water and a hydrocarbon and the resulting mixture agitated to form emulsions. This result is all the more surprising as many of the compounds are only very slightly soluble, and some are insoluble, in either phase.
- FIG. 1 shows the general formula of the products of the present invention.
- FIGS. 2 and 3 exemplify some of the possible structures of R groups of the starting materials and products of the present invention.
