It was observed that when very dilute solutions of hydrogen peroxide were employed for the purpose of destroying pyrogens in aqueous dextran solutions, a marked depolymerization of the polysaccharide molecule occurred. Further study demonstrated this effect to occur over a wide range of temperature, pressure, time, and concentration of hydrogen peroxide. It was therefore possible to use hydrogen peroxide in place of the usual hydrolytic agents, such as acids, for the depolymerization of native dextran to smaller molecular weight fragments suitable for use as a blood plasma extender.

Aqueous Dextran

In this paper, the authors have given information regarding intermolecular interactions of aqueous dextran solution in urea. The behavior of dextran in urea has been examined by the help of ultrasonic interferometer working at frequency 5MHz at different temperatures ranging from 303 K to 323 K in 5K interval. Ultrasonic speed, density, viscosity measurements have been used for the evaluation of thermodynamic parameters like Gibb’s free energy (ΔG) as well as acoustical parameters are acoustic impedance (Z), isentropic compressibility (β), intermolecular free length (Lf ) and relaxation time (τ), etc. The results have been used to throw light on the nature of the interaction among solute and solvent, interpreted in the light of structural rearrangement occurs in the aqueous dextran and urea solution.
