Abstract: METHOD FOR THE PRODUCTION OF SUBSTITUTED 4-CYANOBUTYRIC ACIDS OF THE GENERAL FORMULA:

HOOC-C(-R1)(-R2)-CH2-CH2-CN

IN WHICH R1, AND R2 EITHER SIGNIFY ALKYL GROUPS WITH 1-4 C-ATOMS, OR IN WHICH R1 AND R2 TOGETHER WITH THE CARBON ATOM TO WHICH THEY ARE ATTACHED FORM A CARBOCYCLIC RING, BY OXIDATION OF CORRESPONDING SUBSTITUTED 4-CYANOBUTYRIC ALDEHYDES OF THE GENERAL FORMULA:

HCO-C(-R1)(-R2)-CH2-CH2-CN

IN WHICH R1 AND R2 HAVE THE MEANING INDICATED ABOVE, IN WHICH THE OXIDATION IS CARRIED OUT WITH HALOGEN IN THE PRESENCE OF WATER.

Abstract: METHOD FOR THE PRODUCTIONOF GLUTARIC ACIDS OF THE GENERAL FORMULA I

HOOC-C(-R1)(-R2)-CH2-CH2-COOH

IN WHICH R1 AND R2 SIGNIFY ALKYL GROUPS WITH 1-4 C-ATOMS, OR IN WHICH R1 AND R2 TOGETHER WITH THE CARBON ATOM TO WHICH THEY ARE ATTACHED CAN FORM A CARBOCYCLIC RING, BY OXIDATION AND SAPONIFICATION OF CYANO ALDEHYDES OF THE GERNERAL FORMULA II

HCO-C(-R1)(-R2)-CH2-CH2-CN

IN WHICH R1 AND R2 HAVE THE MEANING INDICATED ABOVE WHICH OXIDATION IS CARRIED OUT WITH CHLORINE AND/OR BROMINE IN THE PRESENCE OF AT LEAST A STOICHIOMETRICAL AMOUNT OF WATER.
