Excess Viscosities and Volumes of Dimethylsulphoxide + Alcohols at 298.15 K

Abstract

Excess viscosities,  η^E,  and volumes, V^E, of dimethylsuiphoxide + methanol,ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, t-butanol andwater were computed from density data, over the whole range of compositionat 298.15 K.  η^Es are negative over the entire range of compositionfor all systems except water, indicating a negative deviation from Raouit'slaw whereas V^Es are positive indicating an expansion in volume. V^E andη^E data was fitted to polynomial function to get values of various coefficients.
