Synthesis, stability, and biodegradability studies of a surface‐active amide
Abstract A homolog pure nonionic surfactant, tetra(ethylene glycol) mono‐ n ‐octaneamide, was synthesized. The surfactant was characterized by determining the critical micelle concentration, cloud point, and biodegradation. Hydrolysis catalyzed by an acid, an alkali, a peroxide, and enzymes [peptida...
