Anwendungen & Verwendung
Verwenden
N-ethylacetamide is a suitable nylon model for mechanistic studies of dye fading. N-Ethylacetamide was used to investigate propylene carbonate and a mixture of N-methylformamide and N-ethylacetamide by broadband dielectric and mechanical shear spectroscopy. It was used in determination of reaction products of OH-oxidation of N-methylpyrrolidone under atmospheric conditions.
