Claims
- 1. A method for the production of a salt of a fatty hydroxamic acid which comprises admixing a methyl or ethyl ester of a fatty acid having 6-22 carbon atoms with a hydroxylamine salt, an alkali metal hydroxide, water, a C.sub.8 -C.sub.22 alcohol and a cationic or non-ionic surfactant to form an emulsion comprising an aqueous phase and an organic phase and allowing the hydroxylamine salt and the ester of the fatty acid to react whereby a clear microemulsion forms comprising an alkali metal salt of the fatty hydroxamic acid, a sodium salt and the surfactant in the alcohol and water.
- 2. A method according to claim 1 wherein said alcohol is decyl alcohol.
- 3. A method according to claim 1 wherein said hydroxylamine salt is hydroxylamine sulfate.
- 4. A method according to claim 1 wherein said ester of a fatty acid is methyl caprylate.
- 5. A method according to claim 1 wherein said alcohol is dodecyl alcohol.
- 6. A method according to claim 1 wherein the resultant salt of the fatty hydroxamic acid is neutralized with acid to thereby form an organic phase and an aqueous phase and the organic phase is recovered.
