Abstract
The paper reports the study of the complexation processes in aqueous
solution of α-CD and DMSO. Cyclodextrins (CDs) (sometimes called
cycloamyloses) are cyclic oligosaccharides formed by glucose units
interconnected by α-(1,4) linkages; α-CD is one of three the most common
CDs. It consists of six glucopyranose units. The speed of ultrasonic waves
has been measured by the resonance method on ResoscanTM System apparatus.
Some collateral data, such as density and heat capacity of the system,
have also been measured. On the basis of the experimental data the excess
adiabatic compressibility was determined. The extremes of the excess
adiabatic compressibility function for different mixture compositions
allowed us to establish the composition of molecular complexes formed in
the solution. The obtained results suggest the formation of the α-CD with
DMSO inclusion complexes with chemical stoichiometric ratio value of 1:1.
