Abstract: Five kinds of dehydroabietylamine salicylidene Schiff bases were synthesized by direct condensation reactions, and their structures were identified by IR and 1H NMR. Their corrosion inhibition activity for copper was studied by static state weight loss method. The result indicated that the inhibition rate of Schiff base for copper increased with the increment of the Schiff base concentration, increment of the time of self-assemble film and decrease of corrosion time. Dehydroabietylamine 5,6-dihydroxy-salicylidene showed the best inhibition activity among these Schiff bases.

Key words: dehydroabietylamine, Schiff base, static weight loss method, corrosion inhibition rate
