Abstract 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 Image Image if appropriate as a mixture with salts of alkenylsuccinic acid half-ester amines of the formula IIa and/or IIb IIa IIb Image Image and/or alkenylsuccinic acid imides of the formula III Image 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 prepara- tion 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 alkoxy- alkylamines 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.
