Synthesis and assessment of Gemini cationic surfactants as inhibitors for corrosion of carbon steel in hydrochloric acid

Novel mono, di, and tetra cationic surfactant molecules were synthesized by quaternization reaction of diamide with cetyl-2-chloroacetate in a 1:1, 1:2, and 1:4. FTIR and 1HNMR revealed the synthetic compounds' chemical structures. Using chemical and electrochemical analysis, synthetic cationic surfactants were tested as corrosion inhibitors for carbon steel in 1. 0 M HCl solutions. The results revealed that the cationic surfactants successfully blocked CSt deposition in the test corrosion medium, with a maximum reduction ratio of 96. 08%.

Fabrication and evaluation of polyurethane cationic surfactants, and their potential on silver nanoparticles stability, surface activity, and biological activity

The cationic polymeric surfactants were tested on a semi-permeable layer to coat or cape Agns. The silver nanoparticles were stable in solution for seven days without aggregation by coating their surfaces, according to the study. The prepared polymeric surfactants with silver nanodispersion demonstrated industrial use against various common G and G bacteria, yeast, and fungi.
