Özet:

 

N-acyl amino acids can be used as active surface agents in  the detergents industry, as well as in the pharmaceutical industry and  cosmetics.  Properties of these compounds are superior to those of  fatty acids soaps and they are not toxic to the environment and have  low Kraft points, because of peptide bonds (CO-NH).  Acylation at the  nitrogen atom can be performed with good yields without catalysts, for  strong nucleophilic derivatives.    The synthesis of some derivatives of 4-azasebacic acid, which are  hydrolysis degradation products from N-(b -cianoethyl)-e  -caprolactam, has been described and the N-acylation processes for  these compounds are also presented.  The obtained products have been  characterized using various methods: IR, UV-VIS, 1H-NMR, 13C-NMR,  elemental analysis, TLC, m.p. (Boethius), and in some cases refractive  index.  The most important surfactant properties of these N-acylated  products were investigated using the surface tension method.  The  related thermodynamic parameters were also calculated.
