Abstract:

The present work used bioproduct nanoparticles as a microemulsioned O/W solution system component. The biomaterial used as a corrosive agent was obtained from the Litopenaeusvannamei shimp shell solution. The bioproduct used in this study was derived from the chitin, the second most available polysaccharide in nature. The chitin is biodegradable, abundant, and it is available at low cost. A phase diagram formed by Renex NP 110 (surfactant-S), 1-butan-ol (cosurfactant-C), kerosene (oil phase- OP), and bioproduct water solution (aqueous phase-AP), in a fixed C/S ratio equal to 1. Three points in MES were chosen within the microemulsioned region (Winsor IV). Point 1 with 85% AP, 13.5% C/S, and 1.5% OP; point 2 with 80% AP; 18.5% C/S, and 1.5% OP; and point 3 had 78.5% AP, 20% C/S, and 1.5% OP. Points 1, 2, and 3 were characterized by particle size, surface tension, temperature, and pH to determine the behavior within each point and its interactions. Following the characterization, the points were tested as corrosion inhibitors in AISI 1020 steel in a NaCl 3.5% medium. The inhibition efficiencies found in this study was above 90% and were similar for the 3 points studied. Therefore, the presence of SME bioproduct is an effective tool in combating the corrosion of steel AISI 1020
