EXCESS VOLUMES OF BINARY-MIXTURES OF TETRALIN WITH N-ALKANES FROM 293.15 TO 313.15 K

Excess volumes V-E for binary mixtures of tetralin with hexane, heptan e, octane, nonane, and decane have been determined from density measur ements at temperatures from 293.15 to 313.15 K. V-E is negative over t he whole composition range and becomes more negative with an increase in temperature. At each temperature, V-E increases as the carbon numbe r of the n-alkane decreases. The cubic expansion coefficients of tetra lin and n-alkanes are also reported.
