A new corrosion inhibitor for protection of low carbon steel in HCl solution

- The inhibitor is mixed type inhibitor with predominant cathodic control.
- Excellent inhibition efficiency (98%) at 60 °C in 1.0 M HCl medium.
- Powerful protection (99.8% inhibition efficiency) against corrosion after 120 h.
- The adsorption of 2-PTA is more than an electrostatic adsorption.
