Abstract:

The overall objective of this project is the establishment of the relation of the hydrophilic-lipophilic ratios of chelating compounds and selected solvents to the corrosion inhibitory action of these compounds in various solvents. Dechelates of 8-quinolinol containing different substituents were selected as the chelates for the initial investigation of physical properties such as dissociation constants, stability constants, hydrophilic- lipophilic ratios and of their corrosion inhibitory action. The results obtained may also allow one to relate the effect on corrosion inhibition of the molecular structure of these derivatives. In this study the needed derivatives were prepared in high purity and their structure proved by the use of non- equivocal synthetic means. The majority of the compounds are new products derived from 8-quinolinol and containing groups such as alkyl, hydroxy, alkoxy, amine and polyethylenoxy. The new compounds besides being considered as corrosion inhibitors may in some cases be potential additives for liquid fuels as antioxidants and metal deactivators, and will be screened for such possibilities.
