Corrosion inhibition of mild steel with schiff base compounds in 1.0 M sulphuric acid solution / Umi Nazira Mohd Shari
Two Schiff base compounds have been synthesized by condensation reaction between 2hydroxybenzaldehyde or 2-hydroxy-3-methoxybenzaldehyde and 1,3-propanediamine in ratio of 2:1. Both Schiff base compounds have been characterized by using basis elemental analysis, FTIR spectroscopy and 1H NMR spectros...
