摘 要:
By using Platycladus orientalis seed oil,diethylene triamine and benzyl chloride as raw materials,imidazoline corrosion inhibitor C(ICI) was synthesized through the reactions of amidation,cyclization and quartemarization.The structures of intermediates were elucidated by IR.Anti-corrision rate was determined by weight-loss method and the potentiodynamic polarization curve method.The resultant ICI exhibited good corrosion inhibition property for steel A20 in the medium of 5% hydrochloric acid.The optimal reaction conditions were obtained from orthogonal experiment:the cyclization reaction time:3.5 h,the molar ratio of P.orientalis seed oil to diethylene triamine:1∶3,and the mass fraction of xylene:25% of total raw material.ICI was found to be an anodic type inhibitor.
