Alkenyl succinic acid derivatives as metal working agents. Abstract of EP0584711 The present invention relates to salts of alkenylsuccinic acid alkoxyalkyl monoamides of the formula Ia and/or Ib if desired mixed with salts of alkenylsuccinic acid(cas:110-15-6) monoester amines of the formula IIa and/or IIb an/or alkenylsuccinimides of the formula III where R, R, A, R, R, n, m and M<(+)> have the meaning mentioned in the description.

The invention likewise relates to a process for the preparation of salts of alkenylsuccinic acid alkoxyalkyl monoamides of the formula Ia and/or Ib, if desired mixed with salts of alkenylsuccinic acid(cas:110-15-6) monoester amines of the formula IIa, IIb and/or alkenylsuccinimides of the formula III, which is characterised in that alkenylsuccinic anhydrides are reacted with alkoxyalkylamines of the formula IV H2N-(CH2)n-O-(A)m-RIV where R, n, m and A have the meaning mentioned in the description, and this reaction is carried out in the presence of an amount of base equimolar to the alkoxyalkylamines of the formula IV or following the reaction an amount of base equimolar to the alkoxyalkylamines of the formula IV is added.

The invention further relates to water- and/or oil-containing formulations for the working of metals, which contain the abovementioned salts of alkenylsuccinic acid(cas:110-15-6) alkoxyalkyl monoamides of the formula Ia and/or Ib, if desired mixed with salts of alkenylsuccinic acid monoester amines of the formula IIa and/or IIb and/or alkenylsuccinimides of the formula III, and to their use as anticorrosion agents, cooling lubricants and metalworking aids.
