<p>Novel quaternary quinolinium compounds are disclosed, being useful as metal corrosion inhibitors. These compounds may be formed by reacting quinoline oligomers with alkylating agents such as benzyl halide, p- -xylenyl dihalide and alkyl sulfates. Examples of the compounds are represented by the formula: <CHEM> wherein n and m are integers, with n being greater than 2 and up to about 200 and m being equal to or greater than 1; R is H or an alkyl group having from 1 to about 20 carbon atoms; R<1> is an alkyl group having 1 to about 20 carbon atoms, X<-> is a chloride, bromide or iodide and Z<-> is an anion selected from BF4<->, SO4 &Ovbar& , ClO4<->, PF6<-> and HSO4<->.</p> |
