Patent ID: 8093414

Claim:
A process for preparing a acylglycinate salt of the formula (II) wherein R 1 is a saturated linear or branched alkyl radical having from 1 to 21 carbon atoms, or a monounsaturated or polyunsaturated linear or branched alkenyl radical having from 2 to 21 carbon atoms and B is a cation derived from a base, and/or the corresponding protonated acylglycine acid, which comprises oxidizing at least one fatty acid monoethanolamide of the formula (I) wherein R 1 is as defined above, with oxygen in the presence of a transition metal catalyst in alkaline medium to form at least one acylglycinate salt of the formula (II) and, in the case of the preparation of the protonated acylglycine acid, additionally reacting the acylglycinate salt or salts of the formula (II) with an acid.
