Alkenylsuccinic acid derivatives as metalworking auxiliaries The present invention relates to salts of alkenylsuccinic acid alkoxyalkyl-half-amides of the formula Ia and/or Ib Ia Ib if appropriate as a mixture with salts of alkenylsuccinic acid half-ester amines of the formula IIa and/or IIb IIa IIb and/or alkenylsuccinic acid imides of the formula III in which R1, R2, A, R3, R4, n, m and M? have the meaning given in the description. The invention also relates to a process for the preparation of salts of alkenylsuccinic acid alkoxyalkyl-half-amides of the formula Ia and/or Ib, if appropriate as a mixture with salts of alkenylsuccinic acid half-ester amines of the formula IIa and IIb and/or alkenylsuccinic acid imides of the formula III, which comprises reacting alkenylsuccinic acid anhydrides with alkoxyalkylamines of the formula IV H2N-(CH2)n-O-(A)m-R3 IV in which R3, n, m and A have the meaning given in the description, and carrying out this reaction in the presence of an amount of base equimolar to the alkoxyalkylamines of the formula IV, or adding an amount of base equimolar to the alkoxyalkylamines of the formula IV after the reaction. The invention furthermore relates to aqueous and/or oil-containing formulations for working metals, which comprise the abovementioned salts of alkenylsuccinic acid alkoxyalkyl-half-amides of the formula Ia and/or Ib, if appropriate as a mixture with salts of alkenylsuccinic acid half-ester amines of the formula IIa and/or IIb and/or alkenylsuccinic acid imides of the formula III, and their use as anticorrosion agents, cooling lubricants and metalworking auxiliaries.
