| Abstract: | Acidizing corrosion inhibitor of Mannich base was synthesized by Mannich reaction with acetophenone, formaldehyde, diethylamine in water, and benzyltriethyl ammonium chloride （BTAC） as phase-transfer-catalyst（PTC）. The evalution of the corrosion behaviour was studied by using the weightlessness method, through orthogonal experiments. The mole raio of raw material： cinnamalde- hydeacetophenone ： aniline= 3 ： 4 ： 3,temperature：100 ℃ ,time：9 h. BTAC is optimum phase transfer catalysts,dosage is 1.15%. |
