| Abstract | ||
| The amine admixture was separated from the industrial waste paint removal (TURCO USA) which consist 60% ethanol amine and 40% n-methylpyrolidone, the admixture was separated purified then the condensation product of the amine admixture was evaluated as inhibitor for acid cleaning processes. On the otherhand the amine admixture was transferred to its benzoate salt. The product was purified,characterised by IR,NMR, and CHN analysis. The products were evaluated as corrosion inhibitors. Several corrosion evaluation parameters were determined using advanced techniques. The parameters investigated were corrosion rate, polarization potential,% of inhibiting efficiency,…etc. The obtained data showed that the separated amine admixture have great efficiency as corrosion inhibitor for acid cleaning , there is no indication for pitting corrosion were observed even in the presence of low concentrations from the amine admixture. The amine benzoate salt showed remarkable efficiency as corrosion inhibitor as examined by potentiostat under statgnent conditions and at different concentrations representative cures are included | ||
