Molecular associations in binary mixture of pyridine and N, N-dimethylacetamide in benzene solution using microwave absorption data
نویسندگان
چکیده
The dielectric relaxation time (τ ) of binary mixtures of different molar concentrations of pyridine (C5H5N) and N, Ndimethylacetamide (DMA) in benzene solution has been calculated by using standard microwave techniques and Gopala Krishna's [Trans Farad Soc, 33 (1957) 767.] single frequency (9.875 GHz) concentration variational method at different temperatures (25, 30, 35 and 40°C). It is found that the dielectric relaxation time (τ ) varies non-linearly with the increasing molar concentration of pyridine in the binary mixture of pyridine and DMA. Hence, solute-solvent and solute-solute molecular associations have been proposed.

متن کاملStudy of Volumetric Properties of N,N-Dimethyl Acetamide and 1-Alkanols Binary Mixtures at 298.15 K
In this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing N,N-dimethyl acetamide (DMAc) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 K. The results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. Deviation values of heavy alcohol have more positive and less negative excess...
متن کاملMolecular dynamics simulation of a binary mixture lubricant for use in hard disk interfaces
In Hard Disk Drives (HDD), it is necessary to decrease the Flying Height (FH) between the head and the disk (currently, FH is around 3-5 nm) so as to increase recording densities. Retaining the solid lubricant has become a difficult proposition owing to intermittent contact between the surfaces. ZTMD and Z are used as solid lubricant to lubricate these interfaces. In this paper, the behavior of...
