| Abstract: | The Mannich base different inhibitor synthesized with formaldehyde（benzaldehyde） ,acetophe none （ acetone）, cyclohexylamine （ divinyl three amine, benzene amine） as the main raw material, the syn thesis conditions for aldehyde ketone amine is 1.5： 1： l ,reaction temperature 90 ℃ ,reaction time is 8 h, pH value of medium is 2. Separation and purification of the synthetic product was confirmed by IR, prod uct groups,using the method of static weight loss and polarization curves of Mannich base synthesis with different monomer inh.ibitor in 15 % hydrochloric acid on the corrosion of steel N80 efficiency. |
