Claims
- 1. An onium surfactant corresponding to the formula X[(CH.sub.2 CH.sub.2 O).sub.m CH.sub.2 --R--CHR'--Q.sup..sym. A.sup..crclbar. ].sub.n, wherein X is a hydrophobic n-valent radical derived by the removal of n-atoms of active hydrogen from an organic compound and corresponds to the hydrophobic portion of a nonionic surfactant having a hydrophilic-lipophilic-balance of from 1 to about 30 and having the structural formula X[(CH.sub.2 CH.sub.2 O--.sub.m H].sub.n ; m is an integer of at least 1 and is the same in each of the above formulae; R is a divalent aromatic hydrocarbon radical of from 6 to about 14 carbon atoms, the chain length of which can be interrupted by oxygen or sulfur atoms; R' is hydrogen or methyl and is methyl only when R is m- or p-phenylene; Q.sup..sym. is a pyridinium radical; A.sup..crclbar. is a compatible anion; and n is an integer of from 1 to 5 and is the same in each of the formulae.
- 2. The surfactant defined by claim 1 wherein n is an integer of from 1 to 3.
- 3. The surfactant defined by claim 2 wherein n is 1.
- 4. The surfactant defined by claim 1 wherein R is m- or p-phenylene or a divalent radical of diphenyl oxide or diphenyl sulfide.
- 5. The surfactant defined by claim 1 wherein R is m- or p-phenylene.
- 6. The surfactant defined by claim 1 wherein m is an integer of from 1 to about 200.
- 7. The surfactant defined by claim 6 wherein m is an integer of from 4 to about 50.
- 8. The surfactant defined by claim 1 wherein X is a hydrophobic n-valent radical derived by removal of active hydrogen from an aliphatic alcohol, a phenol, an organic carboxylic acid or carboxamide, or a polymer of propylene oxide and/or butylene oxide.
- 9. The surfactant defined by claim 8 wherein said radical is derived by the removal of active hydrogen from alkanols, alkenols, alkylphenols, alkanoic acids or amides of from about 10 to about 24 carbon atoms or polymers of propylene oxide and/or butylene oxide.
- 10. The surfactant defined by claim 9 wherein said radical is derived by the removal of active hydrogen from an alkylphenol.
- 11. The surfactant defined by claim 10 wherein said alkylphenol is nonylphenol.
- 12. The surfactant defined by claim 11 wherein m is an integer of from 1 to about 200; R is a divalent radical of benzene; Q.sup..sym. is a pyridinium radical; A.sup..crclbar. is halide, nitrate, sulfate, bisulfate, methylsulfate, lower alkanoate, benzoate, or tosylate; and n is 1.
