Abstract

Zanthoxylum bungeanum seed oil,diethylene triamine and benzyl chloride have been used as raw materials,and imidazoline quaternary ammonium salt (H-1) has been synthesized through amidation, cyclization and quartemarization reactions. Combined with H-2,the corrosion inhibiting capacity of H-1 and the combined corrosion inhibitor are evaluated by weight-loss method. The results show that the prepared H-1 in hydrochloride acid series has very good corrosion inhibiting effect on Steel A20. Its corrosion inhibition efficiency reaches 94.6% ~96.2%. The corrosion inhibiting effect of the new corrosion inhibitor which combined H-1 and H-2 in citric acid series reaches 99.5%. Both of them have very good thermal stability.
