Some Acetophenone Derivatives as Corrosion Inhibitors for Diesel Fuels

Abstract

The corrosion inhibition activities 2.4-dimethylasetophenone semicarbazone (1), 2.4-dimethylacetophenone thiosemicarbazone (2), (E)-3-(2-allyloxy)phenyl)-1-(4-hydroxy-2-methylphenyl)prop-2-en-1-one (3), (E,E)-3-(5-bromo-2-hydroxy­phe­nyl)-1-(4-hydroxy-2-methylphenyl)prop-2-en-1-one th­i­­­­o­se­­mi­car­bazone (4) and 3-hydroxy-3-(2-(2-hydroxy-5-methylphenyl)-2-oxoethyl)indolin-2-one (5) have been studied by weight loss measu­rements for mild steel-3 specimen in diesel fuel. The corrosion rates of the steel-3 are decreased with the increase of the carbazones, chalcone, indolinone con­cen­tra­ti­on, while the inhibition efficiencies are increased.
