摘要

Production method of new benzylidene amino oxy carboxylic acids and carboxylic acid derivatives, of the general formula: **(See formula)** where R1 is halogen, R2 is a halogen, and may also be hydrogen; R4 is hydrogen or CH3; R5 is a possibly branched alkylene group containing up to 3 carbon atoms; R6 is OH, an alkoxy group containing 8 carbon atoms, a benzyloxy group, NH2, alkyl-amino containing up to 3 carbon atoms, or the radical OR7, where R7 is a metal atom, an ammonium group, a hydroxyethyl group -dimethyl ammonium or a hydroxyethyl diethyl ammonium group, it being understood that when R4 is hydrogen, R6 is an alkoxy group, CHARACTERIZED in that a compound of general formula **(See formula)** where R1 to R4 have the same meanings as in formula I and M is a metal atom, reacts with a compound of general formula **(See formula)** where R5 has the same meaning as in formula I, Hal is a halogen atom and R6'' is OH, NH2, an alkyl-amino group, where the alkyl group contains up to 3 carbon atoms, a benzyloxy group or an alkoxy group containing 1 to 8 carbon atoms, the acids obtained being converted into salts by means of bases, if desired.
