The present invention optionally exists as a salt of an alkenylsuccinic acid semi-ester amine of formulas (IIa) and / or (IIb) and / or a mixture with an alkenylsuccinic acid imide of formula (III), A salt of an alkenylsuccinic alkoxyalkyl-half-amide of general formula (la) and / or general formula (lb).n n n n n n n n In the above formula,n n n R 1 , R 2 , A, R 3 , R 4 , n, m and Is as defined herein.n n n In addition, the present invention reacts the alkenylsuccinic anhydride with an alkoxyalkylamine of the general formula (IV), wherein the reaction is carried out in the presence of an equimolar amount of base relative to the alkoxyalkylamine of the general formula (IV), or after the reaction. Salts and / or salts of alkenylsuccinic half-ester amines of the general formulas (IIa) and / or (IIb), if desired, characterized in that they are equimolar to the alkoxyalkylamines of the general formula (IV) A method for preparing a salt of an alkenylsuccinic alkoxyalkyl-half-imide of formulas (Ia) and / or (Ib), which is present as a mixture other than the alkenylsuccinic acid imides of formula (III).n n n n n n n n In the above formula,n n n R 3 , n, m and A are as defined herein.n n n Furthermore, the present invention optionally exists in salts of alkenylsuccinic acid semi-ester amines of formulas (IIa) and / or (IIb) and / or mixtures with alkenylsuccinic acid imides of formula (III). As aqueous and / or oil-containing formulations for metalworking, including salts of alkynalkyl-half-imide of alkenylsuccinic acid of formulas (Ia) and / or (Ib), and as corrosion inhibitors, cooling lubricants and metalworking aids To its use. |
