Streszczenie

Complex studies of the intramolecular versus intermolecular hydrogen bond equilibrium and internal rotation of theN,N-diethylamine group in 2-hydroxy-N,N-diethylbenzamide were conducted. The intramolecular versus intermole-cular process in 2-hydroxy-N,N-diethylbenzamide was studied by UV–Vis, NMR, IR and Vapour Pressure Osmometric(VPO) methods as a function of temperature and concentration in non-polar, basic and protic solvents. The unequalpositions of the ethyl groups were analysed and the energy barrier to the re-orientation was defined by the NMRmethod. This paper presents a study into a complicated nature of competitive interaction 2-hydroxy-N,N-diethyl-benzamide with the environment by means of the aforesaid methods. Copyright
