13 SUMMARY Procedure for obtaining acetic acid derivatives (I) where R4 and R2 are H or groups -CH2-COOH by oxidation of (II) where R and R' are H or groups of -CH2-CH2OH with O2 or a gas that contains it, in the presence of an alkali, demineralized water and Cu-Raney. The reaction is carried out keeping constant a partial pressure of oxygen below 20 Kg/cm? , inside the reactor. The acids (I) obtained as soluble salts, can be isolated and purified by chemical or electrochemical means. Examples of acids (I) are Gly, I.D.A. and N.T.A., useful as nutrients (Gly) and in the synthesis of herbicides (I.D.A. and N.T.A.). Image (II) Image (I)
