Abstract
Novel dicarboxylic ester-acids resulting from the condensation of an alkenylsuccinic anhydride with an aliphatic hydroxy acid having from 2 to about 18 carbon atoms and amine salts of said ester-acid are useful as rust or corrosion inhibitors in organic compositions.
Claims13
A compound having the following general structure:
- ##STR4## where R is alkenyl having from about 4 to about 24 carbon atoms and R' is C.sub.1 -C.sub.16 alkyl.
A composition comprising a major proportion of a liquid or solid organic material, which normally induces deterioration of metallic surfaces when in contact therewith and a minor amount, sufficient to inhibit said deterioration, of a compound having the following general structure:
- ##STR5## where R is alkenyl of from about 4 to about 24 carbon atoms and R.sup.1 is C.sub.1 -C.sub.16 alkyl.
