Some Pyrazolop Pyrimidinone derivatives was synthesized, Purified, and evaluated as corrosion inhibitorby chemical and electrochemical methods at different inhibitor concentrations and temperatures. The inhibition efficiency for corrosion increased with increase in inhibitor concentration, but decreased with temperature. The obtained polarization curves indicate that these compounds act as mixed-type inhibitors. the adsorption process obeys Langmuir isotherm. Thermodynamic activation parameters were computed and discussed.

Keywords: Pyrazolopyrimidine; Corrosion; Inhibitors; Steel; Weight loss; polarization.
