Abstract (en)
[origin: US4722812A] Salts of alkenylsuccinic acid monoamides of the formulae <IMAGE> wherein R1 is C6-C22-alkenyl, preferably C9-C18-alkenyl, A is the protonized radical of an amidoamine of the formula II <IMAGE> II R2 is C5-C22-alkyl, preferably C10-C18-alkyl, C5-22-alkenyl or cycloalkyl, preferably C10-C18-alkenyl or cycloalkyl, R3 is a group of the formula <IMAGE> R4 is either a group of the formula -COR2, R5 at the same time being hydrogen, or R4 and R5 at the same time have the same meaning as R3, Y is hydrogen or methyl, n is a number from 0 to 12 and x is a number from 1 to 3. These compounds are suitable as corrosion inhibitors in water-in-oil emulsions, in particular for petroleum and petroleum products.
