Title: | Shear viscosities of the N-methylformamide- and N,N-dimethylformamide-(C-1-C-10) alkan-1-ol solvent systems | Authors: | Garcia, B Alcalde, R Leal, JM Matos López, JS |
UNESCO Clasification: | 220408 Líquidos | Issue Date: | 1997 | Journal: | Journal of the Chemical Society - Faraday Transactions | Abstract: | Viscosities of some N-methylformamide- and N,N-dimethylformamide-(C-1-C-10) alkan-1-ol binary mixtures have been measured at 298.15 K over the whole composition range. The excess viscosities and excess Gibbs energies of activation for viscous flow, compared with values for other amide-alcohol mixed solvents, suggest that the alcohol size does not play a significant role in the mixture behaviour. The alcohol mixtures with aliphatic amides gave heteroaggregates to a greater extent, the lower the self-association of the pure amides. An analysis in terms of solvent solubility parameters gave good agreement with experimental results. | URI: | http://hdl.handle.net/10553/73452 | ISSN: | 0956-5000 | DOI: | 10.1039/a607876a | Source: | Journal Of The Chemical Society-Faraday Transactions [ISSN 0956-5000], v. 93 (6), p. 1115-1118, (Marzo 1997) |
