Studies On The Synthesis Of N-aromatic Groups-benzyl-phosphoric Acid And Corrosion Inhibition For Metal

This thesis reported the synthesis of three series of twenty - five new aminoalkyl phosphonic acids throngh the reactions of thiazole,thiadiazole,pp'-Diamino-diphenyl-methane and different aromatic aldehyde and phosphorous acid. We found a new kind of reaction which uses a solvent of hexamethy Iphosphoramide. All compounds were identified by element analysis, IR, 1HNMR,31PNMR and GC-MS. The reaction methods and conditions have been analysized too. According to the test of corrosion inhibition properties of target compounds for metal, we discussed the effect of corrosion inhibition on the structure and the composition of compounds concentration and pH of the solution. At last,the composition with Zn salts of inhibition was provided.Target Compounds.
