## Abstract The structure of the intermediate obtained in the come of the nitrationof 2βfurancarboxaldehyde was investigated by means of ^1^H and ^13^C NMR. It was shown unambiguously that this intermediate is 2βacetoxyβ2βdiacetogymethylβ5βnitroβ2,5βdihydrofuran.
The multicomponent self-diffusion of the polyvinyl alcohol (PVA) cryogels prepared by a freezing-thawing treatment of aqueous and water-DMSO solutions of PVA has been studied with the NMR FT-PGSE method. The temperature dependencies of the self-diffusion coefficients, Ds, for the PVA chains have a m
