Sucrose diffusion in aqueous solution

Sucrose diffusion in aqueous solution

The diffusion of sugar in aqueous solution is important both in nature and in technological applications, yet measurements of diffusion coefficients at low water content are scarce. We report directly measured sucrose diffusion coefficients in aqueous solution. Our technique utilises a Raman isotope tracer method to monitor the diffusion of non-deuterated and deuterated sucrose across a boundar...

Molecular Interactions in Binary Mixture of Sucrose in Aqueous NaCl Solution

Density and Ultrasonic velocity Sucrose in 1M NaCl at 298.15K, 303.15K, 308.15K and 313.15K have been measured. Various ultrasonic and solution parameters such as adiabatic compressibility, change and relative change in adiabatic compressibility, acoustic impedance, available volume and free length have been calculated using these data. The present investigation has been used to exploit the pos...

Molecular Mobility of Sucrose in Aqueous Solution Studied by 13C NMR Relaxation

From the tem perature and concentration dependence o f the 13C spin lattice relaxation times o f the 12 carbon atom s o f the sucrose molecule the ro ta tional dynam ics o f the sugar molecules are determ ined. N o indication for conform ational m obility o f the rings is found. The exocyclic hydroxym ethyl groups possess extra m obility. The m odels used for the description are critical­ ly di...
