Volumetric Properties of aqueous solutions of Arabinose, Xylose and Galactose in presence / absence of Sodium Cyclamate

Sugars can affect our blood glucose (sugar), weight and blood fats. Synthetic sugars (artificial sweetener) provide little or no calories or carbohydrate or do not increase blood sugar. In food and pharmaceutical industries, blends of sweeteners are commonly used to design the food products and pharmaceutical doses, the information regarding type and extent of sweetener-sweetener and sweetener -water interactions and taste quality of the solution required. The aqueous solutions of arabinose, xylose and galactose with and without cyclamate are studied. Densities of solutions of arabinose, xylose and galactose in presence of 0.05, 0.15 and 0.3 m sodium cyclamate have been measured at 298.15K. Partial molar volumes, apparent specific volumes, partial molar volumes of transfer and doublet and triplet interaction parameters have been calculated. The information obtained from these parameters has been used to understand type and extent of sweetener-sweetener and sweetener -water interactions and taste quality of the solution.

Effect of different concentrations of aqueous solutions of sodium cyclamate on sugars (mono and disaccharides) are observed by measuring the densities of (sugar + water) and (sugar + water + sodium cyclamate) systems. Densities of aqueous solutions of D (+) mannose (monosaccharide) and D (+) maltose monohydrate (disaccharide) in (0.05, 0.15, 0.3) mol.kg-1 of sodium cyclamate (Na-Cyclamate) at T = 298.15 K have been measured. From experimental values of densities , Vɸ0( partial molar volumes) ΔtrsVɸ0 (partial molar volumes of transfer) ASV (apparent specific volumes) interaction parameters (𝑉𝐴𝐵) and (𝑉𝐴𝐵𝐵 ) have been determined. The calculated values of various parameters have been used to interpret the results in terms of (D (+) mannose – water), (D (+) mannose –water– Na-cyclamate), (D (+) maltose monohydrate – water) and (D (+) maltose monohydrate – water – Na-cyclamate) interactions in sugar– water – Na-cyclamate and quality of taste sense of solutions.

Specific Volumes

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 ofV0Φand ∆trsV0Φwas observed with increase in the concentration of glucose/sucrose. The positive values ofE∞ andV0Φare due to the strong solute-solvent interactions. The positive values of (δ2V0Φ/δT2)psuggest structure making behaviour of sodium cyclamate in water and in presence of glucose and sucrose. The positive values of (∆trsV0Φ) andVABmay 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-1to (0.626 × 10-6) m3×kg-1.

Densities of aqueous solutions of Ethylene glycol (EG), diethylene glycol (DEG), and triethylene glycol (TEG) were measured at temperatures from 293.15 to 318.15 K and molalities ranging from 0.0488 to 0.5288 mol·kg−1. Volumes of all investigated solutions at a definite temperature were linearly dependent on the solute molality; from this dependence the partial molar volumes at infinite dilution were determined for all solutes. It was found that the partial molar volumes at infinite dilution V-2,0 were concentration independent and slightly increase with increasing temperature. The partial molar volumes at infinite dilution V-2,0 or the limiting apparent molar volumes of ethylene glycols were fitted to a linear equation with the number of oxyethylene groups (n) in the solute molecule. From this equation a constant contribution of the terminal (OH) and the (CH2CH2O) groups to the volumetric properties was obtained. The thermal expansion coefficient (α1,2) for all investigated solutions was calculated at temperatures from 293.15 to 318.15 K. The thermal expansion coefficients for all solutes increase with increasing temperature and molality. Values of (α1,2) were higher than the value of the thermal expansion coefficient of the pure water.

Densities of completely miscible (water + methyldiethanolamine) and (water + ethyldiethanolamine) systems have been measured over the full range of compositions at temperatures from 25 to 80 °C. Results of these measurements have been used in calculating excess molar volumes and partial molar volumes of each component. We have also identified different measures of the thermal expansion of these systems and have calculated some of these derivative quantities. The partial molar volumes and their derivatives with respect to temperature provide a basis for extending our understanding of molecular interactions in these (water + organic) systems. Keywords: diethanolamines, excess molar volumes, partial molar volumes, expansivities, aqueous solutions.
