Synthesis, characterization and corrosion inhibition studies of benzoyl thiourea derivatives / Noor Khadijah Mustafa Kamal
A series of benzoylthiourea compounds, namely JV-phenyl-iV '-benzoylthiourea (Bl) and its methoxy (B2), nitro (B3) and chloro (B4) derivatives were successfully synthesized from the reaction of benxoyl chloride with amine derivatives in acetone reflux. The effectiveness of these compounds as co...
