Intermolecular interactions in orthophosphoric
acid—N,N-dimethylformamide system according to viscometric data
Yu. A. Fadeeva (a), L. E. Shmukler (a), and L. P. Safonovaa (b)
The viscosity of an orthophosphoric acid—N,N-dimethylformamide system was measured in the whole region of compositions at 298—338 K. An excess viscosity of the system was analyzed by the data obtained using different model concepts. Calculations suggested that strong intermolecular interactions and the formation of complexes (H3PO4)2•DMF occur in the system.
