摘要：
Excess molar volumes VEm for (1,1,3,3-tetramethylurea + methanol or ethanol or propan-1-ol or butan-1-ol) have been obtained from density measurements at the temperature 298.15 K over the whole mole-fraction range. The excess molar volumes for all the mixtures are negative and decrease in magnitude with an increase of alkyl-chain length of the alkan-1-ol molecule. The VEm values for (1,1,3,3-tetramethylurea + an alkan-1-ol) are compared with those reported for (N,N-dimethylacetamide + an alkan-1-ol). © 1992 Academic Press Limited All rights reserved.
