Densities of sodium cyclamate (Na-cycl) in water and (0.1, 0.3, and 0.5) m (glucose/sucrose) have been measured at (298.15, 303.15, 308.15, and 313.15) K. From density values, partial molar volumes (V0Φ), expansion coefficient (E∞), Hepler’s constant (δ2V0Φ/δT2)p, apparent specific volumes (ASV), partial molar volumes of transfer (∆trsV0Φ), doublet (VAB) and triplet (VABB) interaction coefficients have been calculated. An increase in the values of V0Φ and ∆trsV0Φ was observed with increase in the concentration of glucose/sucrose. The positive values of E∞ and V0Φ are due to the strong solute-solvent interactions. The positive values of (δ2V0Φ/δT2)p suggest structure making behaviour of sodium cyclamate in water and in presence of glucose and sucrose. The positive values of (∆trsV0Φ) and VAB may be due to the interactions between hydrophilic group (–OH, C=O, and –O–) of glucose/sucrose and sodium ion of sodium cyclamate. All solutions studied exhibit sweet taste because ASV of all solutions ranges from (0.569 × 10-6) m3×kg-1 to (0.626 × 10-6) m3×kg-1.
